PS3 Cell

[MikeB]

- More processors on one chip. 8 of which used on the PS3, newer chips sport more processors on a chip.
- Each processor has its own relative large amount of dedicated memory operating at cache-like speeds (fast, efficient) each with its own DMA controller, each SPEs acts as an independent system-on-a-chip of its own. Allowing them to operate far more asynchronously (efficient).
-Very high internal bandwidth, data is moved around a ring amongst the SPEs. Good for streaming.

The design is very modern and innovative. Some non-crucial legacy stuff has been removed from the PPE and even more so with regard to the SPEs (which requires devs at this point to do more manually, but is far more efficient and powerful). So this design requires a lot of redesign regarding legacy software to take advantage of, but doing so yields better results on other multi-processor or multi-core architectures as well but to a lesser extend.
