The Cell setup is excellent for throughput.
- First step of course is to not share main Ram between GPU and CPU like on the 360, separate buses maximise potential (less latency).
- Low latency main RAM, like XDR is crucial for getting the most out of a 8 processor chip like the PS3 Cell chip.
- But most importantly IMO are the SPE's dedicate memory. They function as real system memory, but operates as fast as cache memory. This together with the huge EIB ring bandwidth is what allows the Cell to reach a near linear performance increases when tapping more SPEs.
