The Frequency of Apple A5X in the New iPad Confirmed: Still Running at 1GHz
by Kristian Vättö on March 13, 2012 12:02 PM ESTWhile Apple's new iPad won't be available until Friday, some users have gotten their hands on the new models and done some preliminary benchmarks. A Vietnamese site, tinhte.vn, posted a screenshot of GeekBench running on the new iPad (model iPad3,3) which showed a score of 756 and a 1.00GHz ARMv7 processor. For comparison, the GeekBench score of iPad 2 is 751, which confirms that the GeekBench reading of the frequency is indeed correct.

In a nutshell, the processor in A5X is largely the same as in A5: We are looking at two Cortex-A9 cores running at up to 1.0GHz. Some people were anticipating an increase in the clock speed as A5X is expected to be 32nm while A5 was based on older 45nm process node, but it appears that Apple used all the gains of a smaller process node for better graphics.
The GeekBench screenshot also confirms 1GB of RAM, although that was fairly certain even before the release thanks to leaked screenshots.
The GPU, especially its frequency, is still a mystery but hopefully we will be able to get our hands on the new iPad as soon as possible and start testing.

iPad 3 GLBenchmark results are in. The low level benchmarks shows pretty much a perfect 2x scaling from the iPad 2 in the tests that don't already hit the 60 fps cap, so clock speed appears the same going from SGX543MP2 to SGX543MP4. The MP architecture seems to have very efficient scaling on these theoreticals.
In the game benchmarks, the iPad 3 is ~70% faster than the iPad 2 in Pro 720p and ~55% faster in Egypt 720p so there appears to be a bottleneck somewhere. Seeing the Geekbench results show memory performance hasn't changed, Apple likely retained the existing 2x32-bit LPDDR2-800 setup meaning the iPad 3 is bandwidth constrained. If Apple wanted to focus on the GPU over the CPU, you'd think they would have moved to LPDDR2-1066 to maximize the SGX543MP4 since they need as much GPU performance as possible for the Retina Display.

InterestingSo in the end the A5X is about 2x (Egypt 720p) to 3x (Pro 720p) faster than Tegra 3 for graphics.

I think that's pretty much what is expected in terms of the theoretical raw speedup manufacturers claim and the real world difference developers and users see once everything is put together. Hopefully the iPad 2 GPU had a lot of unused performance so game developers won't be trading increased graphical effects to drive the extra pixels in the iPad 3.archer75 - Tuesday, March 13, 2012 - link
Now let's see that at the native resolution of the ipad 3 display.milli - Tuesday, March 13, 2012 - link
How do you conclude that the chip is 32nm?If you ask me it's still 45nm.

Agreed. It's not clear at all.tipoo - Tuesday, March 13, 2012 - link
I was thinking the same, the CPU is clocked the same and has the same architecture, the post above showed the GPU runs at the same speed, so the only difference on the SoC seems to be moving from the MP2 to the MP4 graphics. If they moved to 32nm, would that really need the new heat spreader? The old one already had an EMI shield over it, so I'm guessing that's what the metal bit is for.Kristian Vättö - Tuesday, March 13, 2012 - link
I didn't state that it's 32nm for sure but that has been our guess.ananduser - Tuesday, March 13, 2012 - link
Dear Kristian,Engadget had posted through one of its readers a similar GeekBench for the Asus TP tablet; score 1900. Would that allow Nvidia to make a presentation slide and state that its SoC is more than twice as faster than Apple's "new" ipad Soc ?
