Here’s some technical information on a possible new cell chip for the PS4. We’ve heard about the Cell 3 chip with 32 SPEs and 2 PPEs, well it seems IBM are due to change all that. The new possible chip now is the design for 32 SPEs and 4 PPEs.
Some features of the new chip:
100% backward compatible
Performance on PPE significantly better
Performance per SPE equal or better
Significantly better on applications that benefit from new instructions
Better inter-SPE latency
More on-chip memory
Better main memory latency and bandwidth
Apparently IBM are aiming for 1 TeraFLOPS of performance with this new chip. To put that into perspective the current Playstation 3 Cell chip is only capable of 204 GigaFLOPS.
The new cell is projected for around 2010/2011, with 2011 rumored to be the year we’ll see a PS4 release…coincidence?
Edit: Since publishing this post the download link to the IBM .pdf is now broken. Sadly it seems the .pdf has disappeared entirely from the site, however i have managed to find a number of screenshots from the relevant pages mentioned above – hope that helps.
