On the 360, there's no distinction between graphical/system memory, it's just a total of 512 MB to be divided as developers prefer. Like on the PC, the PS3 setup is much better (twice the bandwidth). Of course should be noted both types of memory can be accessed by both the GPU and CPU. The PS3's fast XDR Ram has very low latency which is very important to CPUs, especially for the Cell processor. Potentially if needed the GPU can access both types of RAM simultaneously, latency isn't much of an issue for GPUs (the RSX also has relatively large cache) and such an approach would significantly add bandwidth which is more important. |
That's totally off-topic.
