Will we see XDR ram on our video cards?

[zyklon69]

What do you guys think, will ati or nvidia use this ram?

[jAkUp]

XDR is expensive. 768MB-1GB would be quite expensive I suppose.

I doubt we will see XDR unless we are starved for memory bandwidth.

[superklye]

This stuff is still around? There was like this super-hype for about a month about a year ago and then I never heard anything about it again.

I think the ps3 uses it.

I think the ps3 uses it.

yup, The PS3's main ram is 256MB of XDRAM.

yup, The PS3's main ram is 256MB of XDRAM.

But PS3's Video RAM is GDDR3
BTW Ps3's XDR speed is 25.6GB/s (64bit) and
VRAM is 22.4 (128 bit) or less (I don't know if it was downgraded after all)

XDR has a huge bandwidth per pin but it also has big latencies

that's why it's not "ideal" for video,

There is a possibility of Video cards with XDR if the use embedded framebuffer
or big caches for compensating the latencies
So they could take benefit from lower pin count and use that
for multi GPU in on card (but that's only speculation)

I don't see why XDR would be used unless either Nvidia or AMD buys Rambus.
The graphics manufacturers use RAM that meets or exceeds XDR bandwidth with lower latencies. And Rambus has higher licensing costs. What's the benefit?

XDRAM is used for everything in a console, base memory and cache for the video.
