Lol! Lol! I wonder why PC GPU's use GDDR5 Ram??? Maybe MS should send Nvidia and AMD an email telling them to use Esram instead. Lmfao! MS shill talks up his own product while dismissing the competition without a shred of evidence to back it up with!

But eDRAM is best when the programmer know it is there and can fully utilize it. Use of eDRAM in PCs difficult. Even when a developer want to use it they must make code for PCs with or without eDRAM. But eDRAM is perfect for consoles with their standardized hardware.

Modern graphics card use eDRAM to: http://www.theinquirer.net/inquirer/news/2265428/intel-haswell-chips-will-have-onpackage-dram-for-cpu-and-gpu

Even a Sony Lead system architect of the PS4 admits that eDRAM gives a performance boost: http://techon.nikkeibp.co.jp/english/NEWS_EN/20130401/274313/?P=2

It isn't perfect for consoles as theirs only 32MB of it. It then becomes a puzzle to solve and a bottleneck. GDDR5 Ram is the better overall solution!

 

PS2 had embedded ram, 360 has embedded ram, gamecube, wii, wiiu, even psp according to wikipedia. Seems the puzzle has been solved by devs long ago.


Why would you want or need a tiny amount of embedded ram when you can use one unified pool of GDDR5 ram? This is exactly what Mark Cerny is saying. The extra die that MS lost by adding the 32mb ESRam Sony have benefitted from having a far more powerful GPU and a much easier platform to develop for.
