Joe, re: "But 8MB of ram in addition to the GPU still ends up with a huge chip, far beyond the budget of low end solution." How big is 8MB of eDRAM? Ace's actually has a news post up on this subject: "NEC's Full-Metal eDRAM Process" aceshardware.com Original source article: eetimes.com NEC plans for about 0.35 micron^2 DRAM cell using a 0.13 micron process. I assume this is for a 1-bit cell so 8MB would be... 1M micron^2 = 1mm^2 8MB = 8M x 8 (bits/byte) x 0.35 micron^2 = 22.4 mm^2. Assuming no math (or technical) errors... yes, 8MB is BIG. I was clearly adrift in considering this for a low-end graphics solution to "save" on traces and chip count at a cost (space and process challenges) which is not yet acceptable for high-end GPU. -PT
