Currently there's a trend discussing the performance of either the PS4 and Xbox One and placing much emphasis on the GPU and memory bandwidth of the systems rather than the CPU performance. This shift of focus to the GPU isn't anything new, particularly to PC gamer's -- indeed it's been steadily happening for some time (a fact both AMD and Nvidia would remind us of at regular opportunity). The GPU's performance has risen tremendously in comparison to that of the CPU, with performance per watt scaling at a much better rate. Both Sony's and Microsoft's respective machines are powered by the AMD Jaguar, which barely breaks over 100GFLOPS of computing power. You could be forgiven for the initial reaction to lay the blame squarely at the feet of the consoles CPU's for being "low power" but even the highest performance CPU's of the PC generally fall at only around the 200GFLOP range. The PS4′s GPU meanwhile puts out almost 2TFLOPS of computing performance and that's slow compared to a gaming PC's where we can already buy GPU's of at least 5TFLOPS+, and with dual GPU's you'll reach 8 to 10TFLOPS of computing performance (single precision of course).
