Finally some interesting mobile device comparisons are emerging with the release of new benchmarks. These are system/platform comparisons, not hardware comparisons except for the inclusive cases where devices use the same OS. We've had those comparisons for a long time though, the interesting part emerging now is regarding platform comparisons. http://anandtech.com/show/6877/the-great-equalizer-part-3/ The new GL bench 2.7 compares all major platforms (3D Mark is not out for iOS yet) and is quite demanding for shader performance. Given its target hardware, it is not designed to benefit devices with high memory bandwidth, which is what the older GPU's tested excel at, but synthetic tests point out their strengths and weaknesses compared to the more modern GPU's in most of the SoC's tested (Nexus 7/Surface RT, tegra 3 based devices, it is basically Nvidia 7000 series tech). Fillrate: iPad4's A6X is a fillrate monster, with the Nexus 10 doing decently. Both of these need high fillrates for the high screen resolution they sport. Intel HD4000 is very close to a 7900GTX while GT420m is in a league of its own. Windows RT takes a hit over Android comparing the Nexus 7 to Surface RT. Lit Triangle throughput: The 7000 series with it's non-unified architecture takes a hit here. The more modern GPU's in the x86 systems catch them up/overtake. Now a less synthetic, more real-world test: Being a mobile orientated test, like mobile games this test does not make use of large, high detail assets and thus doesn't scale so well past a certain threshold of memory bandwidth. The old desktop GPU's don't look so good because of this. The more modern ones on the other hand, do very well. Intel HD4000 is 3 times faster than A6X with GT420m is 6 times faster. We can make some pretty good comparisons with laptops and desktops with these numbers. Even the lowest end modern Ultrabook has 3 times the graphics capability of an iPad4 when taking into account the much larger OS/API overhead on the Windows system. A low end desktop PC with a discreet GPU would be at least 10x that of an iPad4. Consoles on the other hard are a little harder. The PS3 is fairly comparable to the 7900GS or 7800GT being better in some ways and worse in others. However, it has a very low level API, is a completely closed system (optimisations) and has Cell to help it out with vertex processing (6000/7000 series' major weakness). I would have to say that it is at least twice as capable as the iPad4 under the same bandwidth demands. Under higher bandwidth demands, the PS3 would pull further ahead. Next-gen consoles will be 10-20x ahead of iPad4. For tablets, A6X is mighty impressive for a tablet SoC. I look forward to seeing what IMG series 6 'Rogue' will bring. I'm also curious as to what will come from above, in the form of Haswell closing the TDP gap a little more and AMD's Kabini with 4 jaguar cores and GCN GPU. For phones, Qualcomm's S600 is damn impressive. I await tests with the Galaxy S4 as it uses faster memory than the HTC One, it should be close to the iPad4. So S800 with it's Adreno 330 GPU should be very interesting. I hope they include iPhone 5 in the next comparison.
