The Dirty Little Secret About Mobile Benchmarks

Last updated: June 18, 2014

This article has had over 13,000 views. Thanks for reading it.

When I wrote this article over a year ago, most people believed mobile benchmarks were a strong indicator of device performance. Since then a lot has happened: Both Samsung and Intel were caught cheating and some of the most popular benchmarks are no longer used by leading bloggers because they are too easy to game. By now almost every mobile OEM has figured out how to “game” popular benchmarks including 3DMark, AnTuTu, Vellamo 2 and others. Details. The iPhone hasn’t been called out yet, but Apple has been caught cheating on benchmarks before, so there is a high probability they are employing one or more of the techniques described below like driver tricks. Although Samsung and the Galaxy Note 3 have received a bad rap over this, the actual impact on their benchmark results was fairly small, because none of the GPU frequency optimizations that helped the Exynos 5410 scores exist on Snapdragon processors. Even when it comes to the Samsung CPU cheats, this time around the performance deltas were only 0-5%.

11/26/13 Update: 3DMark just delisted mobile devices with suspicious benchmark scores. More info.

The old saying about 'Lies, damned lies, and statistics' couldn't be more true when it comes to benchmarks.

The old saying about ‘Lies, damned lies, and statistics’ couldn’t be more true when it comes to benchmarks.


Mobile benchmarks are supposed to make it easier to compare smartphones and tablets. In theory, the higher the score, the better the performance. You might have heard the iPhone 5 beats the Samsung Galaxy S III in some benchmarks. That’s true. It’s also true the Galaxy S III beats the iPhone 5 in other benchmarks, but what does this really mean? And more importantly, can benchmarks really tell us which phone is better than another?

Why Mobile Benchmarks Are Almost Meaningless

  1. Benchmarks can easily be gamed – Manufacturers want the highest possible benchmark scores and are willing to cheat to get them. Sometimes this is done by optimizing code so it favors a certain benchmark. In this case, the optimization results in a higher benchmark score, but has no impact on real-world performance. Other times, manufacturers cheat by tweaking drivers to ignore certain things, lower the quality to improve performance or offload processing to other areas. The bottom line is that almost all benchmarks can be gamed. Computer graphics card makers found this out a long time ago and there are many well-documented accounts of Nvidia, AMD and Intel cheating to improve their scores.

    Here’s an example of this type of cheating: Samsung created a white list for Exynos 5-based Galaxy S4 phones which allow some of the most popular benchmarking apps to shift into a high-performance mode not available to most applications. These apps run the GPU at 532MHz, while other apps cannot exceed 480MHz. This cheat was confirmed by AnandTech, who is the most respected name in both PC and mobile benchmarking. Samsung claims “the maximum GPU frequency is lowered to 480MHz for certain gaming apps that may cause an overload, when they are used for a prolonged period of time in full-screen mode,” but it doesn’t make sense that S Browser, Gallery, Camera and the Video Player apps can all run with the GPU wide open, but that all games are forced to run at a much lower speed.

    Samsung isn’t the only manufacturer accused of cheating. Back in June Intel shouted at the top of their lungs about the results of an ABI Research report that claimed their Atom processor outperformed ARM chips by Nvidia, Qualcomm and Samsung. This raised quite a few eyebrows and further research showed the Intel processor was not completely executing all of the instructions. After released an updated version of the benchmark, Intel’s scores dropped overnight by 20% to 50%. Was this really cheating? You can decide for yourself — but it’s hard to believe Intel didn’t know their chip was bypassing large portions of the tests AnTuTu was running. It’s also possible to fake benchmark scores as in this example.

    Intel has even gone so far as to create their own suite of benchmarks that they admit favor Intel processors. You won’t find the word “Intel” anywhere on the BenchmarkXPRT website, but if you check the small print on some Intel websites you’ll find they admit “Intel is a sponsor and member of the BenchmarkXPRT Development Community, and was the major developer of the XPRT family of benchmarks.” Intel also says “Software and workloads used in performance tests may have been optimized for performance only on Intel microprocessors.” Bottom line: Intel made these benchmarks to make Intel processors look good and others look bad.

  2. Benchmarks measure performance without considering power consumption – Benchmarks were first created for desktop PCs. These PC were always plugged into the wall, had multiple fans and large heat-sinks to dissipate the massive amounts of power they consumed. The mobile world couldn’t be more different. Your phone is rarely plugged into the wall — even when you are gaming. Your mobile device is also very limited on the amount of heat it can dissipate and battery life drops as heat increases. It doesn’t matter if your mobile device is capable of incredible benchmark scores if your battery dies in only an hour or two. Mobile benchmarks don’t factor in the power needed to achieve a certain level of performance. That’s a huge oversight, because the best chip manufacturers spend incredible amounts of time optimizing power usage. Even though one processor might slightly underperform another in a benchmark, it could be far superior, because it consumed half the power of the other chip. You’d have no way to know this without expensive hardware capable of performing this type of measurements.
  3. Benchmarks rarely predict real-world performance — Many benchmarks favor graphics performance and have little bearing on the things real consumers do with their phones. For example, no one watches hundreds of polygons draw on their screens, but that’s exactly the types of things benchmarks do. Even mobile gamers are unlikely to see increased performance on devices which score higher, because most popular games don’t stress the CPU and GPU the same way benchmarks do. Benchmarks like GLBenchmark 2.5 focus on things like high-level 3D animations. One reviewer recently said, “Apple’s A6 has an edge in polygon performance and that may be important for ultra-high resolution games, but I have yet to see many of those. Most games that I’ve tried on both platforms run in lower resolution with an up-scaling.” For more on this topic, scroll down to the section titled: “Case Study 2: Is the iPhone 5 Really Twice as Fast?”

    This video proves shows that the iPhone 5s is only slightly faster than the iPhone 5 when it comes to real-world tests. For example, The iPhone 5s only starts up only 1 second faster than the iPhone 5 (23 seconds vs. 24 seconds). The iPhone 5s only loads the Reddit.com site 0.1 seconds faster than the iPhone 5. These differences are so small it’s unlikely anyone would even notice them. Would you believe the iPhone 4 shuts down five times faster than the iPhone 5s? It’s true (4 seconds vs. 21.6 seconds).

    Another video shows that even though the iPhone 5s does better on most graphics benchmarks, when it comes to real world things like scrolling a webpage in the Chrome browser, Android devices scroll significantly faster than a iPhone 5s running iOS 7. See for yourself in this video.

  4. The iPhone 5s appears to do well on graphics benchmarks until you realize that Android phones have almost 3x the pixels

  5. Some benchmarks penalize devices with more pixels — Most graphic benchmarks measure performance in terms of frames per second. GFXBench (formerly GLBenchmark) is the most popular graphics benchmark. Apple has dominated in the scores of this benchmark for one simple reason. Apple’s iPhone 4, 4S, 5 and 5s displays all have a fraction of the pixels flagship Android devices have. For example, in the chart above, the iPhone 5s gets a score of 53 fps, while the LG G2 gets a score of 47 fps. Most people would be impressed by the fact that the iPhone 5s got a score that was 12.7% higher than the LG G2, but when you consider the fact the LG G2 is pushing almost 3x the pixels (2073600 pixels vs. 727040 pixels), it’s clear the Adreno 330 GPU in the LG G2 is actually killing the GPU in the iPhone 5s. The GFXBench scores on the 720p Moto X (shown above) are further proof that what I am saying is true. This bias against devices with more pixels isn’t just true with GFXBench, you can see the same behavior with graphics benchmarks like Basemark X shown below (where the Moto X beats the Nexus 4).
  6. More proof that graphics benchmarks favor devices with lower-res displays

  7. Some popular benchmarks are no longer relevantSunSpider is a popular JavaScript benchmark that was designed to compare different browsers. However, according to at least one expert, the data that SunSpider uses is a small enough benchmark that it’s become more of a cache test. That’s one reason why Google came out with their V8 and Octane benchmark suites, both are better JavaScript tests than SunSpider.” According to Google, Octane is based upon a set of well-known web applications and libraries. This means, “a high score in the new benchmark directly translates to better and smoother performance in similar web applications.” Even though it may no longer be relevant as an indicator of Java-script browsing performance, SunSpider is still quoted by many bloggers. SunSpider isn’t the only popular benchmark with issues, this blogger says BrowserMark also has problems.
  8. SunSpider is a good example of a benchmark which may no longer be relevant

    SunSpider is a good example of a benchmark which may no longer be relevant — yet people continue to use it

  9. Benchmark scores are not always repeatable – In theory, you should be able to run the same benchmark on the same phone and get the same results over and over, but this doesn’t always occur. If you run a benchmark immediately after a reboot and then run the same benchmark during heavy use, you’ll get different results. Even if you reboot every time before you benchmark, you’ll still get different scores due to memory allocation, caching, memory fragmentation, OS house-keeping and other factors like throttling.

    Another reason you’ll get different scores on devices running exactly the same mobile processors and operating system is because different devices have different apps running in the background. For example, Nexus devices have far less apps running in the background than a non-Nexus carrier-issued devices. Even after you close all running apps, there are still apps running in the background that you can’t see — yet these apps are consuming system resources and can have an affect on benchmark scores. Some apps run automatically to perform housekeeping for a short period and then close. The number and types of apps vary greatly from phone to phone and platform to platform, so this makes objective testing of one phone against another difficult.

    Benchmark scores sometimes change after you upgrade a device to a new operating system. This makes it difficult to compare two devices running different versions of the same OS. For example, the Samsung Galaxy S III running Android 4.0 gets a Geekbench score of 1560, which the same exact phone running Android 4.1 gets Geekbench score of 1781. That’s a 14% increase. The Android 4.4 OS causes many benchmark scores to increase, but not in all cases. For example, after moving to Android 4.4, Vellamo 2 scores drop significantly on some devices because it can’t make use of some aspects of hardware acceleration due to Google’s changes.

    Perhaps the biggest reason benchmark scores change over time is because they stress the processor increasing its temperature. When the processor temperature reaches a certain level, the device starts to throttle or reduce power. This is one of the reasons scores on benchmarks like AnTuTu change when they are run consecutive times. Other benchmarks have the same problem. In this video, the person testing several phones gets a Quadrant Standard score on the Nexus 4 that is 4569 on the first run and 4826 on a second run (skip to 14:25 to view).

  10. Not all mobile benchmarks are cross-platform — Many mobile benchmarks are Android-only and can’t help you to compare an Android phone to the iPhone 5. Here are just a few popular mobile benchmarks which are not available for iOS and other mobile platforms (e.g. AnTuTu Benchmark, Octane, Neocore, NenaMark, Quadrant Standard and Vellamo).
  11. Mobile benchmarks are not time-tested — Most mobile benchmarks are relatively new and not as mature as the benchmarks which are used to test Macs and PCs. The best computer benchmarks are real world, relevant and produce repeatable scores. There is some encouraging news in this area however — now that 3DMark is available for mobile devices. It would be nice if someone ported other time-tested benchmarks like SPECint to iOS as well.
  12. Existing benchmarks don't accurate measure the impact of memory speed or throughput

    Existing benchmarks don’t accurately measure storage performance on things like video playback

  13. Inaccurate measurement of memory and storage performance — There is evidence that existing mobile benchmarks do not accurate measure the impact of faster memory speeds or storage performance. Examples above and below. MobileBench is supposed to address this issue, but it would be better if there was a reliable benchmark that was not partially created memory suppliers like Samsung.
  14. Existing benchmarks don't accurately measure storage performance on things like video playback

    Existing benchmarks don’t accurate measure the impact of memory speed or throughput

  15. Inaccurate measurement of the heterogenous nature of mobile devices — Only 15% of a mobile processor is the CPU. Modern mobile processors also have DSPs, image processing cores, sensor cores, audio and video decoding cores, and more, but not one of today’s mobile benchmarks can measure any of this. This is a big problem.

Case Study 1: Is the New iPad Air Really 2-5x as Fast As Other iPads?

There have been a lot of articles lately about the benchmark performance of the new iPad Air. The writers of these article truly believe that the iPad Air is dramatically faster than any other iPad, but most real world tests don’t show this to be true. This video compares 5 generations of iPads.

Benchmark tests suggest the iPad Air should be much faster than previous iPads

Benchmark tests suggest the iPad Air should be much faster than previous iPads

Results of side-by-side video comparisons between the iPad Air and other iPads:

  • Test 1 – Start Up – iPad Air started up 5.73 seconds faster than the iPad 1. That’s 23% faster, yet the Geekbench 3 benchmark suggests the iPad Air should be over 500% faster than an iPad 2. I would expect the iPad Air would be more than 23% faster than a product that came out 3 years and 6 months ago. Wouldn’t you?
  • Test 2 – Page load times – The narrator claims the iPad Air’s new MIMO antennas are part of the reason the new iPad Air loads webpages so much faster. First off, MIMO antennas are not new in mobile devices; They were in the Kindle HD two generations ago. Second, apparently Apple’s MIMO implementation isn’t effective, because if you freeze frame the video just before 1:00, you’ll see the iPad 4 clearly loads all of the text on the page before the iPad Air. All of the images on the webpage load on the iPad 4 and the iPad Air at exactly the same time – even though browser-based benchmarks suggest the iPad Air should load web pages much faster.
  • Test 3 – Video Playback – On the video playback test, the iPad Air was no more than 15.3% faster than the iPad 4 (3.65s vs. 4.31s)

Reality: Although most benchmarks suggest the iPad Air should be 2-5x faster than older iPads, at best, the iPad Air is only 15-25% faster than the iPad 4 in real world usage, and is some cases it is no faster.

Final Thoughts

You should never make a purchasing decision based on benchmarks alone. Most popular benchmarks are flawed because they don’t predict real world performance and they don’t take into consideration power consumption. They measure your mobile device in a way that you never use it: running all-out while it’s plugged into the wall. It doesn’t matter how fast your mobile device can operate if your battery only lasts an hour. For the reason top benchmarking bloggers like AnandTech have stopped using the AnTuTu, BenchmarkPi, Linpack and Quadrant benchmarks, but they still continue to propagate the myth that benchmarks are an indicator of real world performance. They claim they use them because they aren’t subjective, but then them mislead their readers about their often meaningless nature.

Some benchmarks do have their place however. Even though they are far from perfect they can be useful if you understand their limitations. However you shouldn’t read too much into them. They are just one indicator, along with product specs and side-by-side real world comparisons between different mobile devices.

Bloggers should spend more time measuring things that actually matter like start-up and shutdown times, Wi-Fi and mobile network speeds in controlled reproducible environments, game responsiveness, app launch times, browser page load times, task switching times, actual power consumption on standardized tasks, touch-panel response times, camera response times, audio playback quality (S/N, distortion, etc.), video frame rates and other things that are related to the ways you use your device.

Although most of today’s mobile benchmarks are flawed, there is some hope for the future. Broadcom, Huawei, OPPO, Samsung Electronics and Spreadtrum recently announced the formation of MobileBench, a new industry consortium formed to provide more effective hardware and system-level performance assessment of mobile devices. They have a proposal for a new benchmark that is supposed to address some of the issues I’ve highlighted above. You can read more about this here.

A Mobile Benchmark Primer

  • 3DMark is one of the most popular computer benchmarks for graphics. It’s also one of the better mobile benchmarks for iOS and Android. Although it calls itself a graphics benchmark, experts like AnandTech say it stresses the CPU more than graphic benchmarks like GFBench. 3DMark is also heavily-threaded, so its Unlimited Physics tests tends to reward quad-core CPUs. ***
  • AndEBench-Pro is a new suite of tests measuring CPU, GPU, memory and storage subsystem performance. It also gauges XML parsing, GUI rendering, image manipulation, data compression, and cryptography tasks embedded in actual workloads. This benchmark is a product of an EEMBC workgroup led by Intel with members from Imagination Technologies and NVIDIA. One of the first benchmarks to be available in Mandarin. This apps is based on AndEBench, which also appears to be rough around the edges and gets only 3 stars in Google Play.
  • Androbench is a good way to measure the storage performance of your Android Devices
  • AnTuTu is a popular benchmark which tests the CPU, memory, graphics and I/O performance. Although AnandTech and Engadget are no longer using AnTuTu, it’s still one of the most popular Android benchmarks.
  • Basemark ES 3.0 measures the graphics performance of OpenGL ES 3.0 enabled devices. ***
  • Basemark X is a good cross-platform graphics benchmark based on the latest Unity 4.0 engine. One of the more demanding graphic benchmarks. ***
  • Basemark OS II is a system-level CPU benchmark designed to measure the overall performance of Android, iOS and Windows mobile devices. ***
  • BenchmarkXPRT – You won’t find the word “Intel” on the BenchmarkXPRT website, but if you check the small print on some Intel websites you’ll find they admit “Intel is a sponsor and member of the BenchmarkXPRT Development Community, and was the major developer of the XPRT family of benchmarks.” Intel also says “Software and workloads used in performance tests may have been optimized for performance only on Intel microprocessors.” Bottom line: Intel made these benchmarks to make Intel processors look good and others look bad. These benchmarks should not be used.
  • BenchmarkPi is one of several benchmarks that measures performance by calculating Pi. This benchmark isn’t recommended because it only tests the CPU and is no longer used by AnandTech.
  • BrowserMark is a cross-platform browser benchmark, but it has some issues that make cross-platform comparisons questionable.
  • CaffeineMark is a series of online tests that measure the speed of Java programs.
  • Certimo is a new rating system for mobile devices that is supposed to accurately reflect consumer experiences. Categories include battery life, browsing, display quality, infotainment, messaging, multimedia, overall and performance. It’s too early to say how good the system is.
  • CFBench is a newer benchmark that specializes in multi-core tests
  • CompuBench is benchmark that tests general-purpose computing on the graphics processing unit (GPGPU). It’s creator says it’s the first professional RenderScript benchmark testing the compute performance of heterogeneous multi-core systems of mobile devices supporting the RenderScript API. ***
  • Dhrystone is an older synthetic computing benchmark program which provides an indication of CPU “integer” performance.
  • The original Geekbench was designed to test the CPU and memory, so it was all about raw performance. Geekbench 3 is crossplatform. It runs on Android, iOS, Max OS, Linux and Windows. It measures both single-core and multi-core performance using tests that are supposed to simulate real-world scenarios. ***
  • GFXBench (formerly GLBenchmark) is one of the most popular GPU benchmarks. The GLBenchmark Egypt HD tests are close to the workload you get on most retail games today. The GLBenchmark T-Rex HD test is more stressful and that’s why you’ll see much lower frame rates. ***
  • Google Octane is another browser benchmark that focuses on JavaScript performance. It effectively replaces V8 because it adds another five tests to the ones already in V8
  • Google V8 is another browser benchmark that includes eight tests focused on JavaScript performance
  • Kraken is a benchmark created by Mozilla that runs in your browser and measures JavaScript performance. According to AnandTech, Kraken is designed to stress more forward-looking algorithms. AnandTech recently introduced Kraken into their browser test suite, because they were worried SunSpider is becoming too much of a browser optimization target.
  • Linpack measures floating point performance of the CPU. Although LinPack is no longer used by AnandTech, it’s still used by Engadget and others. ***
  • MobileBench is a new benchmark that will be released in 2014 that claims to provide more effective hardware and system-level performance assessment
  • MobileXPRT – You won’t find the word “Intel” on the BenchmarkXPRT website, but if you check the small print on some Intel websites you’ll find they admit “Intel is a sponsor and member of the BenchmarkXPRT Development Community, and was the major developer of the XPRT family of benchmarks.” Intel also says “Software and workloads used in performance tests may have been optimized for performance only on Intel microprocessors.” Bottom line: Intel made these benchmarks to make Intel processors look good and others look bad. MobileXPRT should not be used.
  • Pi calculates how long it takes to calculate Pi up to 10 million digits, but it’s not a very useful mobile benchmark because it only measures one thing.
  • Quadrant Standard claims to test CPU, memory, I/O and graphics — but it’s mostly a CPU benchmark.
  • Quadrant Pro claims to test CPU, memory, I/O and graphics — but it’s mostly a CPU benchmark. It’s unclear what you get for $24.99 other than it publishes your results. ***
  • SunSpider is a JavaScript benchmark, which is showing signs of its age
  • WebXPRT – You won’t find the word “Intel” on the BenchmarkXPRT website, but if you check the small print on some Intel websites you’ll find they admit “Intel is a sponsor and member of the BenchmarkXPRT Development Community, and was the major developer of the XPRT family of benchmarks.” Intel also says “Software and workloads used in performance tests may have been optimized for performance only on Intel microprocessors.” Bottom line: Intel made these benchmarks to make Intel processors look good and others look bad. WebXPRT should not be used.
  • Vellamo is the second most popular Android benchmark. It’s known as an HTML5 browser performance test, but the Vellamo 3 also tests determine the efficiency and performance of your CPU. It also has one of the best collections of multi-core benchmarks. It’s worth mentioning that the Vellamo 3 Browser tests include SunSpider, Google’s Octane and 14 more tests. ***
  • *** Indicates benchmarks which are used by top OEMs and chip manufacturers

    Benchmarks like this one suggest the iPhone 5 is twice as fast as the iPhone 4S.

    Case Study 2: Is the iPhone 5 Really Twice as Fast?

    Note: Although this section was written about the iPhone 5, this section applies equally to the iPhone 5s. Like the iPhone 5, experts say the iPhone 5s is twice as fast in some areas — yet most users will notice little if any differences that are related to hardware alone. The biggest differences are related to changes in iOS 7 and the new registers in the A7.

    Apple and most tech writers believe the iPhone 5’s A6 processor is twice as fast as the chip in the iPhone 4S. Benchmarks like the one in the above chart support these claims. This video tests these claims.

    In tests like this one, the iPhone 4S beats the iPhone 5 when benchmarks suggest it should be twice as slow.

    Results of side-by-side comparisons between the iPhone 5 to the iPhone 4S:

    • Opening the Facebook app is faster on the iPhone 4S (skip to 7:49 to see this).
    • The iPhone 4S also recognizes speech much faster, although the iPhone 5 returns the results to a query faster (skip to 8:43 to see this). In a second test, the iPhone 4S once again beats the iPhone 5 in speech recognition and almost ties it in returning the answer to a math problem (skip to 9:01 to see this).
    • App launches times vary, in some cases iPhone 5 wins, in others the iPhone 4S wins.
    • The iPhone 4S beats the iPhone 5 easily when SpeedTest is run (skip to 10:32 to see this).
    • The iPhone 5 does load web pages and games faster than the iPhone 4S, but it’s no where near twice as fast (skip to 12:56 on the video to see this).

    I found a few other comparison videos like this one, which show similar results. As the video says, “Even with games like “Wild Blood” (shown in the video at 5:01) which are optimized for the iPhone 5s screen size, looking closely doesn’t really reveal anything significant in terms of improved detail, highlighting, aliasing or smoother frame-rates.” He goes to say, “the real gains seem to be in the system RAM which does contribute to improved day to day performance of the OS and apps.”

    So the bottom line is: Although benchmarks predict the iPhone 5 should be twice as fast as the iPhone 4S, in the real-world tests, the difference between the two is not that large and partially due to the fact that the iPhone 5 has twice as much memory. In some cases, the iPhone 4S is actually faster, because it has less pixels to display on the screen. The same is true for tests of the iPad 4 which reviewers say “performs at least twice as fast as the iPad 3.” However when it comes to actual game play, the same reviewer says, “I couldn’t detect any difference at all. Slices, parries and stabs against the monstrous rivals in Infinity Blade II were fast and responsive on both iPads. Blasting pirates in Galaxy on Fire HD 2 was a pixel-perfect exercise on the two tablets, even at maximum resolution. And zombie brains from The Walking Dead spattered just as well on the iPad 3 as the iPad 4.”

      hahahaha … so iphone 4s is faster than iphone 5? you should have both device ipad 2 to ipad 3 is a diff story than iphone 4s to iphone 5! ok lets throw the benchmark out!! you can test the power of the both device it the graphics not in the speech recognition is different.. try nova 3 and modern combat 4 on both device iphone 4s is laggish! try the camera… speech recognition is a diffent strory man… try to have a research and go back to school!

      • Listen Einstein, I didn’t say iPhone 4S is faster. Whoever made that video showed it WAS DEFINITELY faster at SOME things. The point was NOT that the 4S was faster, the point was that the benchmarks predicted it should have been MUCH slower and it’s not. No doubt the iPhone 5 kills the 4S on gaming and other stuff but even then it’s not as fast as the benchmarks predict it should be.

      can you please explain why you use just some pictures from anandtech and try hard to make explain ? why you didn’t choose off screen 1080p test and try explain how iphone 5s beat android devices ? cause it’s very hard to believe what you say when you just chose that pictures because just make sense what you saying and ignoring the other facts that you can’t explain or understand , all the test you put it here there is off screen test for it !!!
      in the end you like it or not anandtech who you just say they are best deside it is the BEST

      • You’re missing the entire point of the article. This article has nothing to do about which phone is best. It questions the effectiveness of mobile benchmarks. I include screenshots which support the claims I’m making. The fact that SOME benchmarks favor devices with less pixels is just common sense if you think about it.

        • clevier says:

          i know , but what about when both be tested for the pixels like off screen test ?
          and don’t get me wrong it was really informative post thank you

        • The iPhone 5s does very well of most off-screen tests and it’s clear the GPU in the iPhone 5s is excellent. Whether that makes a difference in real-world apps is the question I’m trying to get people to consider. Thanks for your comments.

    12. TadzioPazur says:

      I completely agree with the author, as the benchmarks are so flawed in trying to reduce a whole lot of parameters to just a few numericals that can then be compared.
      Yet, as editors like to point out, review without quantitative analysis (even if flawed to some extent) is not as useful as one that cover products with some metric measurements.
      Usefulness of some data is beyond doubt (storage size, battery life, LCD brightness/angles, device boot time), others are debatable (amount of RAM, CPU clockspeed, storage read/write speed) while others are completely meaningless (AES raw throughput or Stream TRIAD throughput in mobile devices).

      I’d like to add however, that banning a bunch of benchmarks because device vendors cheated them rendered us depend on benchmarks that we know very little of (*cough* GeekBench *cough*). This is even worse, as the inflation of results of – let’s say linpack – is only possible to a small extent (otherwise one would end up with incorrect computation results), closed-source benchmarks that yield results incompatible with anything outside can provide results that are off by an order of magnitude.

      All in all, I cannot praise the Final Thoughts enough.
