Game engine executable code is usually tiny, why would you need that much CPU memory? It's the textures and audio which usually take much memory. So it makes much more sense for the RSX to take advantage of the XDR Ram than it would be for the Cell to use the GDDR3. Again low latency is important to CPUs. |
Because occlusion culling, animation, and physics is handled by the CPU and it needs full access to every vertex that makes up every polygon in the system; on top of this the CPU has to handle the loading, preloading and streaming of data from the disc.
