[] Apple A5X Die Size Measured: 162.94mm^2, Samsung 45nm LP Confirmed

Contrary to what we thought yesterday based on visual estimation of the A5X die, Chipworks has (presumably) measured the actual die itself: 162.94mm^2. While the A5 was big, this is absolutely huge for a mobile SoC. The table below puts it in perspective.

CPU Specification Comparison CPU Manufacturing Process Cores Transistor Count Die Size Apple A5X 45nm? 2 ? 163mm2 Apple A5 45nm 2 ? 122mm2 Intel Sandy Bridge 4C 32nm 4 995M 216mm2 Intel Sandy Bridge 2C (GT1) 32nm 2 504M 131mm2 Intel Sandy Bridge 2C (GT2) 32nm 2 624M 149mm2 NVIDIA Tegra 3 40nm 4+1 ? ~80mm2 NVIDIA Tegra 2 40nm 2 ? 49mm2

The PowerVR SGX 543MP2 in Apple's A5 takes up just under 30% of the SoC's 122mm^2 die size, or around 36.6mm^2 just for the GPU. Double the number of GPU cores as Apple did with the A5X and you're looking at a final die size of around 160mm^2, which is exactly what Chipworks came up with in their measurement.

Update: Chipworks confirmed the A5X is still built on Samsung's 45nm LP process. You can see a cross-section of the silicon above. According to Chipworks' analysis, the A5X features 9 metal layers.

Note that this is around 2x the size of NVIDIA's Tegra 3. It's no surprise Apple's GPU is faster, it's spending a lot more money than NVIDIA to deliver that performance. From what I hear, NVIDIA's Wayne SoC will finally show what the GPU company is made of. The only issue is that when Wayne shows up, a Rogue based A6 is fairly likely. The mobile GPU wars are going to get very exciting in 2013.
