iPad 2 specs discerned, 900MHz dual-core ARM CPU and PowerVR SGX543MP2 GPU blow away graphical benchmarks

iFixit may have physically uncovered Apple’s latest silicon, but it’s the processor gurus that have discovered what’s truly inside — using software benchmarks, they’ve unearthed the speeds and feeds of the Apple A5. As you’ll no doubt be aware having read our headline above, there actually isn’t a 1GHz CPU at the helm, as AnandTech and IOSnoops report the dual-core ARM chip is dynamically clocked around 900MHz, likely in search of reduced power consumption. Perhaps more interestingly for all you gamers in the audience, the iPad 2 reports that it has a dual-core PowerVR SGX543MP2 GPU on the die as originally foretold — and, spoiler alert — it mops the floor with both the original iPad and the Motorola Xoom . Though the new chip didn’t quite demonstrate 9X the graphical prowess of its predecessor, it rendered 57.6 frames per second in a GLBenchmark test where the (admittedly higher-res) Tegra 2 tablet managed only 26.7fps, and last year’s iPad pulled only 17.6fps. That’s some serious Tai Chi . Hit up our source links to see the difference it can make in games like Infinity Blade . Update: Though it sure sounds like there’s a dual-core ARM Cortex A9 in there, that’s not yet a proven fact — we only know that it’s a dual-core ARM v7 chip which performs relatively similarly in non-graphical tests.
