Larger silicon lets Apple's A5 chip beat Nvidia's Tegra 2, handsomely

The results of the GL Benchmark tests pitting a bunch of GPUs show that Apple’s A5 chip beats Nvidia’s Tegra 2 silicon to the graphics punch. Apple advertises the A5 silicon as being twice as fast than the previous generation with up to ninefold jump in graphics performance. But how was Apple able to beat Nvidia’s graphics wizards at their own game?
Tiernan Ray over at Barron’s has an interesting explanation – Apple’s chip is two and a half times larger than Nvidia’s. More precisely, the A5 measures 122 square millimeters versus 49 square millimeters for the Tegra 2 chip. No matter what people think, size matters. Read on…
