Chipset Exynos 4212 Quad CPU Quad-core 1.4 GHz Cortex-A9 GPU Mali-400MP http://www.gsmarena.com/samsung_i9300_galaxy_s_iii-4238.php http://www.gsmarena.com/samsung_i9300_galaxy_s_iii-4238.php The Mali-400MP is quad-core (x2 from before) http://en.wikipedia.org/wiki/Exynos http://en.wikipedia.org/wiki/Exynos This seems feasible, with similar battery life, as they've shrunk the process to half the area: 45^2 vs 32^2. Its performance per core is comparable the sgx543 of the iPhone/iPad. http://www.arm.com/products/multimedia/mali-graphics-hardware/mali-400-mp.php http://www.arm.com/products/multimedia/mali-graphics-hardwar... vs http://en.wikipedia.org/wiki/PowerVR#Series_5XT http://en.wikipedia.org/wiki/PowerVR#Series_5XT (though depends on the clock actually used) So, this phone's GPU is similar to the "new iPad"3 (quad-core sgx543). (Apple have also done a shrink, but it's only used in the old iPad 2 so far...) I think quad-core CPUs are past the point of diminishing returns (consider the latest Transformer); multi-core are still hard to code for, and they are usually underutilized on desktops. Note: the iPad 4 is likely to have the next in the GPU series (Rogue 6200), which apparently is comparable to the xenos GPU in the xbox360. So, it's leapfrog, jumping x2 as far each year.

Both ARM CPU's and GPU's seem to jump 2x in performance every year, so at least so far, they've been moving faster than Moore's Law. Personally, I'm looking forward to the Exynos 5250 chip, with a dual core 2 Ghz Cortex A15 CPU and a Mali T-604 GPU (new Midgard architecture) that's supposed to be 4x faster than Mali400 (the original in GS2), so probably 2x or faster than the current overclocked Mali400 in GS3 (will also support OpenCL). This chip should appear in some tablets and phones, and maybe even a Chromebook by the end of the year. I'm also looking forward to them pairing Cortex A15 with the ultra-low-power Cortex A7, maybe in a 2+2 core configuration. Samsung mentioned that they might be ready with Cortex A7 by the end of the year, but in general we can expect Cortex A7 to arrive next year. I would prefer this over something like a pure Cortex A15 quad core chip, which should also appear next year. Starting with 2014 we should see the successor of Cortex A15 in dual core version, based on the 64 bit ARMv8 architecture.
