superchunk said: WHat about a Power7 CPU with its normal cache? |
POWER7 L3 cache is eDRAM.
Each POWER7's core, with its associated cache, have 30mm^2.... I know a console based POWER7 could be smaller because it not need full four double-precision floating point units but an three core is to be bigger then 30mm^2 in 45nm.
The custom CPU on Wii U have to be small with eDRAM to fit in 30mm^2 and have three cores.
Edit - Thinking better a heavly customized tri-core POWER7 with eDRAM can fit in 30mm^2... you have to remove all things the console don't need and so you have a small POWER7... with normal DRAM cache I think is unlikely to reach the 30mm^2 in 45nm.
