drkohler said: You might rephrase that statement. The point is there is only one address bus to ram, so yes, cpu and gpu "share ram", all of it... This is essentially the point of NextBox using edram memory. The gpu can talk to the edram while somebody else can talk to the main ram, at the same time - different address busses. We will see how developers are actually going to use the edram. For starters, my suspicion is that developers will simply use the edram as a frame buffer and call it a day.. |
Yeap.... I think what I said can be understood in the wrong way.
What I meam is the RSX to use more than 256MB RAM it need to ask to Cell to address and share the RAM... so it need use bus between RSX and Cell and SystemRAM... in PS4 the GPU and CPU have access to all the RAM.
About the eSRAM I think MS will try to make this transparent to developers.
