6800 with ddr3 available in feb!

performance compariosn

So how do the two chips compare, performance-wise? Thanks for the info!

Too early to tell probably, but good news nonetheless. I have made a commitment to buy a 9860 (God willing) after the newer nVidia card is released.

No more waiting for the latest + greatest nonsense.

hmmm how much will it cost to upgrade the 6800 go w/ddr1 to ddr3?

nice nice, cuz that 6800 to x800 switch is rediculous-pricewise

at this rate i'm betting those of us on backorder wont get shipped till feb..maybe we'l get switched from geforce to x800 back to the new geforces =/

I expect the 6800Go revision 2 with GDDR3 to be quite a bit faster than the MR X800 in all benchmarks. Early reviewers of the 6800Go revision 1 and the MR X800 indicated that NVidia intend to release a 450/600(1200) MHz version of the 6800Go - this is partially confirmed by their website which puts the GDDR3 version's memory speed at 600(1200)MHz. Compare this with the 1st revision 6800Go which runs at 250/300(600) MHz stock and you've got a 1.8-2x increase in clock speeds. Adam's recent benchmark comparisons of both the 6800Go revision 1 and the MR X800 in stock and overclocked configurations showed that the 6800Go's performance scaled pretty much linearly on the same scale as the overclock being achieved (i.e. a 1.3x overclock achieved synthetic scores 1.3x higher in 3DMark '03 and '05).

Taking all this into account a 1.9x increase in the stock clock speed of the 6800Go revision 2 (over the revision 1 card) could translate into 3DMark '03 and '05 scores of as much as 13,600 and 5,800 (using current drivers) respectively - and that's before you take overclocking into account.

By this measure the 6800Go revision 2 if released at the currently projected clock speeds should "wipe the floor" with the MR X800 and be as fast as any desktop card currently on the market.

i don't see it anywhere on their web site

don't see where it says anything about the new DDR3 chips. i see the Geforce logo, but nothing more.

Not quite, since the card will still only have 12 pipes instead of the 16 some desktops have. Regardless however, it should be faster than anything we've ever seen before, and easily capable of playing games like Doom3 close to Max settings.

Good point, in my excitement at the projected synthetic benchmark scores I got a bit carried away. This factor may even limit the linear progression of the benchmark scores giving less of an increase than I projected - but I believe it'll still be much quicker than the MR X800 (possibly 30-40% quicker) and a substantial improvement over the revision 1 card.

well maybe we get lucky and somebody in development is using his brain - saying that it is senseless to pair 256mb gddr3 ram with 12 pipes then 16 and this way limit the card again. to argue about power consumtion is pointless since the 9860 isn't a laptop but at best a transportable. so who cares bout batterylife - gimme processing power

do you need also this modification for the 6800go ddr3?

Because there is a physics limit you run into with cooling down a 16 pipe GPU. nVidia currently has dual-slot cooling for it's .13u 16 pipe 6800 Ultra. You cannot get that amount of cooling into even a desknote format, where space is still a premium.

If you "go all out" for a processor, GPU, & cooling, you just end up with a desktop tower.
