R6XX for Xbox2 (questions for Dave Baumann)?

[Sonic]

How about an R500 with eDRAM?

I think it will have edram but i don't think it will just be an r500.

I'm also thinking 64-96 megs or edram as that should be more than enough for 4-6x fsaa . With 256-512 megs of ram for video 256 megs of system ram shared with the sound chip.

an R500 derivative with eDRAM, yes.

probably one of the most likely possibilities

64 MB of eDRAM? That might be a bit overload considering the transistor count alone, I know the density is a lot tighter but come on.

 

[jvd]

why not . I mean they will be using an old vpu by the time the xbox 2 comes out

If the release date is at the end of 2006, the amount of edram needed might not be that great. The bandwidth from GDDR-4 (Micron and Samsung going with a smaller micron process than .11 nm to fab memory) could potentially yield substantial bandwidth for a console. Dedicating transistors for shader execution instead of bandwidth seems more probable.

of course by reading the psp threads you will know that edram prices drop quicker than standard ram .

So it would make more sense to add more edram than gddr. IT will offer alot better performance too
