He was talking GPU alone... If it wasn't a hack job then why was it so inefficient? For example all the modifications done to it were to hack stuff out to better fit the PS3 (ROPs) and it still has the major hallmark of an AGP interface GPU because the reads to main GPU memory from the CPU are stupidly slow. |
Boy oh boy, why would the Cell need to use the GPU's memory in normal situations? In general it makes no sense as the XDR is faster and provides far lower latencies for the CPU to work with.
Changing a game engine to allow the GPU (big amounts of graphics data) to make use of the XDR memory however can make sense and it can do so at great speed. Actually the RSX can access both types of memory simultaneously, about doubling the potential bandwidth.
