DemoCoder said:But XB360's eDRAM isn't really eDRAM in the sense of the PS/2's eDRAM. It's on an external chip (not embedded on the R500 core) which means its bandwidth is limited from eDRAM's true potential. I've seen conflicting reports, but the true raw bandwidth of XB360's "eDRAM" is more like 32gb/s-64gb/s.
phat said:What? Off-chip eDRAM that's only 10MB in size? When Sony managed to fit 32MB of it onto their GS-32?
And how do you get 256GB/s between two chips without a 2,048-bit wide bus, which would not work between two chips anyway...
GS embedded ram was DRAM, not SRAM.Npl said:PS2 was not eDRam, it was static Ram (just logic, no capacitors - fastes, but needs most space - eg. All CPU L1 caches are static)

There would be need more than 200 Mtransistors to employ a 4 Mb SRAM
