Yes, still CELL can't really access 'local memory'
But why would you do that other than for some developer tests?
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.
d RSX is much slower when it tries to access CELL:s memory when you compare it to X360 architechture
Latency isn't much of an issue for GPUs, bandwidth is the GPU can potentially can take advantage of both XDR and GDDR3 simultaneously to increase bandwidth (of course the CPU in such a situation will have to wait).
ts not really the same
I was referring to devs usually picking the cheapest solution available to them. (Actually it's probably the publisher which sets such requirements)
