xman said: The issue with BOTH is RAM they are both limited to 512gb, thats what really is the limiting factor |
512 MB. And make no mistake,the 360 has 512mb unified architecture + 10mb embedded Dram on the GPU. The ps3 limits the gpu to 256 so it`s more complicated.
Plus,the PS3's bandwidth holds the system back. For example even though the Ps3 can acces memory simultaneously with CPU and GPU at the same time it is significantly slower at doing so than the 360. In the time it takes PS3 CPU and GPU to acces memory once each at the same time, the 360 cpu can access twice and GPU 3 times or vice versa. Even though the 360 has to do it in turn! So thats 2 read and writes to memory for PS3 (1 cpu and 1gpu) and 5 read and writes for 360 (2 cpu and 3 gpu or vice versa) in the same time frame. The bandwidth numbers are available so you can do the math.
