I feel this topic needs its own discussion rather than be buried in next-gen hardware prediction thread. eDRAM has proven invaluable for PS2 and XB360, but does it still have a future? As I see it, the move towards deferred rendering makes eDRAM less useful, so it may be time to drop it. But then I've no idea of the costs between plenty of eDRAM and plenty of main RAM BW.
So, is there a future for eDRAM? How much would be ideal? Should we go with TBDR on a smaller tile, or if we go TBDR couldn't we just use SRAM? Are any other platforms using eDRAM, such as mobiles?
