The time has now come for the 8800 GTX to stand down off the pedastal, and the new higher clocked 'Ultra' model to take its place. The NDA's just dissapeared and as such there is a rush of coverage beginning to flood the web with plenty of benchmarks and info on NVIDIA's latest flagship weapon. I'll update the list below over the next 24 hrs as more reviews show up.
It's also worth mentioning that although the new Ultra variant is basically just a higher clocked GTX, not all Ultra cards are clocked with the same frequencies. The Inquirer have reported that although the stock clock speeds of the Ultra are 612MHz GPU / 1080MHz MEM, Sparkle plan to release their Calibre P880 Ultra card with frequencies of 650MHz / 2250MHz thanks to the residing TEC Peltier cooler onboard. It wasnt long ago that these exact higher than stock clockspeeds of the Ultra were rumoured to be the actual clockrates of the OEM sample, not a souped up model by one of NV's partners (of which i'm sure we'll see more partners follow suit, especially the likes of XFX, BFG and EVGA).
WHAT HAPPENS WHEN YOU take the fastest video card on the planet and turn up its clock speeds a bit? You have a new fastest video card on the planet, of course, which is a little bit faster than the old fastest video card on the planet. That's what Nvidia has done with its former king-of-the-hill product, the GeForce 8800 GTX, in order to create the new hotness it's announcing today, the GeForce 8800 Ultra.
There's more to it than that, of course. These are highly sophisticated graphics products we're talking about here. There's a new cooler involved. Oh, and a new silicon revision, for you propellerheads who must know these things. And most formidable of all may be the new price tag. But I'm getting ahead of myself.
