65nm Cell processor for servers - is it only a matter of time before it shows up in the PS3?
The new PowerXCell 8i is a far more than a process shrink from 90nm to 65nm. IBM currently runs the processor at the same 3.2GHz as before, so that the power consumption can be lower.
- The new design also uses less expensive DDR2 memory instead of the original Rambus XDR memories, allowing for further potential cost savings;
- Total memory capacity is now expandable up to 32GB.
- Expanded double precision floating point support on all eight Cell cores.
- 190 TFlops of double precision throughput, 5x as much as previous Cell
The "QS22" adapter card will be available at the end of May for $9,995 - it has sockets for two PowerXCell 8i's.
IBM is apparently also considering some other Cell products in the future:
- Multi-Chip modules packing two dies into one package
- 16 and 32 cell cores instead of the current 8
Hmm... I wonder how many Cell cores a future PS4 will have?
