D12U will be first Nvidia GPU with GDDR5 support

D12U will be first Nvidia GPU with GDDR5 support

Nvidia won't take DDR5 on until 2009 according to several memory manufacturers - that's about the same time that Larrabee hits the market.

Nvidia hasn’t even launched its D10U product yet and we’re already starting to hear whispers about the company’s next-next-next generation graphics products.

Several memory manufacturers have confirmed that the first Nvidia GPU to feature support for GDDR5 memory will be the D12U part, which is said to be currently scheduled for a late 2009 launch.

Obviously, D12U probably hasn’t even left the drawing board yet, but it’s clear that Nvidia is already in discussions with memory manufacturers about the supply of high-speed GDDR5 memory. We already know that ATI’s next-generation graphics cards support GDDR5, and we’re likely to see the new memory technology used on the RV770XT-based products.

GDDR5 is currently made on a 70nm node, but by the time Nvidia gets around to using it, it’ll be manufactured on a 55nm process – that’s expected to happen at some point during 2009. What’s more, by the end of Q1 2009, memory manufacturers expect to have doubled the density of the technology, meaning higher capacity memory kits will be available for newer graphics cards.

Finally, many memory manufacturers suggest that GDDR5 will be limited to high-end products for the next twelve to eighteen months, by which time the price should have dropped significantly enough for it to be cost-effective at more volume-orientated price points.

Looking forward to what graphics power will be available come the end of 2009? Tell us in the forums.

This news kinda broke way too early for me, but its cool to know. I wonder though if it really is going to be nvidia's first gpu to support gddr5 if thats the case amd will have the market to themselves for awhile.

any numbers on what MHz range GDDR5 has (like 2500MHz - 3300MHz or something)?

edit: I say bring in some XDR2 DRAM and see what that does to graphics performance, running at 8000MHz (yes eight thousand) even if its just a tech demo e-peen thing for the company that tries it.

You do know it is from RAMBUS eh?

According to fudzilla the current G200 already support GDDR5 but it is unclear if it will be implemented, but I am sure some partners will.. :)
Maybe D12U will be GDDR5 and upwards only.. ;)

I think the GDDR5 on the 4870 is supposed to be @ 3217Mhz or something silly like that.

Rambus RAM is too expensive and requires a fat bus on the die which is expensive too.

So, this is the D12U - the GTX 2x0 is the D10U. Either the D11U is the 55nm version of D10U or this is very far off.

ahh, I've got it now. perhaps the ps3 could have been cheaper if they ditched XDR ram then. still, it wold be interesting to see as a tech demo as I said earlier (as in 'this is what we could make if we wanted' like the HD 3850 X3)
