what are the differences between the two consoles?
CPU:
The CPU of Xbox 360 has vector processing power and a dot product instruction. The console also has three general purpose CPU cores and each core has 128 vector registers per hardware thread with a shared 1 MB L2 cache and a dot product instruction. The CPU of Sony Playstation 3 allows an environment where 87.5% work is DSP calculation and 12.5% work is general purpose computing.
GPU:
The GPU of Xbox 360 is more 안전놀이터 powerful than that of Sony playstation 3. The Xbox 360 GPU has larger number of transistors and the total programmable GFLOPs number is almost equal.
