OUR INQUIRER STORY here suggests that Nvidia's just released ? but not yet shipped to retail - high-end sixth-generation GeForce 6800 Ultra (NV40), has had its clock frequencies raised.
We can now clarify this further and say that all the indications are that these higher-clocked parts will be introduced under the model name 'Nvidia GeForce 6800 Ultra Extreme'.
For any Nvidia board partner to ship a GeForce 6800 Ultra, the GPU clock must be set to at least 400MHz and the memory at 550MHz. These frequencies are as per the NV40 reference samples Nvidia initially shipped to the press during the last few weeks, and upon which all reviews to date have been based.
As we also indicated, the press samples of the 'GeForce 6800 Ultra Extreme' that have just been shipped feature a 450MHz core but with the same 550MHz memory clock (1100MHz G-DDR3).
But if you want any 6800 Ultra you better raid your piggy bank fast, because we've heard that only 2000 of the 10,000 NV40 GPUs produced are expected to qualify at the '6800 Ultra' clock rate of 400MHz.
If that's not, "Limited Edition" enough and you want some of the 6800 Ultra Extreme action that select reviewers are receiving just now, you should be forming a line outside retailers that specialise in only Gainward, and maybe XFX products.
This is because it's been suggested that only 200 or so pieces might make the grade as a '6800 Ultra Extreme' with its 450MHz clock.
Gainward will almost certainly introduce both air and liquid cooled variants of GeForce 6800 Ultra. Two of the models seem likely to be called the Gainward PowerPack! Ultra-2600 TV/DVI and the Gainward CoolFX Ultra-2600 'Golden Sample'.
We suggest that the 450MHz 6800 Ultra Extreme core will form only the starting point for Gainward's overclockers wet-dream, the liquid-cooled CoolFX Ultra-2600 'Golden Sample', and we suggest that 500MHz is Gainward's target for the GPU Core.
If Gainward can mate such a core with GDDR3 that is officially rated to 600MHz, and extract a bit more frequency there too, then as things look, such a product may be the only one based upon Nvidia GeForce 6800 Ultra that could topple ATI's most high-end 16x1 R420 offering.
Oops, this is an ati thread . . . the latest
And if you thought Nvidia's recently launched GeForce 6800 Ultra (NV40) was incredibly rapid ? which it definitely is, and impressively so ? hold on to your hats for the ATI Radeon X800XT, er well, no, not the Radeon X800XT.
All is definitely not as it seems in the battle of 3D graphics marchitecture, and the product being analysed by hardware reviewers everywhere is in fact named the Radeon X800XT Platinum.
In contradiction to earlier reports, the ATI reference boards seeded to hardware reviewers, and clocked at 520MHz VPU and 560MHz memory, will be called the XT Platinum range.
Indeed specs of 'vanilla' Radeon X800XT seem as yet unconfirmed, so on Tuesday the line up will run from 12x pipeline Radeon X800PRO to 16x pipeline Radeon X800XT Platinum.
Numerous reports indicate that the Radeon X800XT Platinum is quicker overall, and by some margin, than the initial Nvidia GeForce 6800 Ultra reference boards that have been reviewed.
Quicker everywhere that is except, we understand, in OpenGL where GeForce 6800 Ultra and Nvidia's superior OpenGL ICD decidedly has its measure.
But it's with Direct3D games like Far Cry - ironically much promoted by Nvidia under it's The Way it's Meant To Be Played programme, and being rolled out as one of the first Pixel Shader 3.0 (PS 3.0) games where PS 2.0 Radeon X800XT Platinum shines the most.
Indeed we understand that at a resolution of 1280x1024 with 4xAA (Anti-Aliasing) and 8xAF (Anisotropic Filtering), with all the eye-candy on max, X800XT Platinum can easily sustain an average of more than 47FPS on a system based around an AMD Athlon 64 FX 51.
As we reported earlier Nvidia has been rushing around to reinvent it's flagship 3D accelerator ? previously reviewed as the GeForce 6800 Ultra - as an even higher-clocked GeForce 6800 Ultra Extreme. No doubt, this rather predictable kneejerk reaction has been based upon the extremely positive feedback to Nvidia from friendly journalists on the performance of ATI's forthcoming Radeon X800XT Platinum.
But, as we reported earlier, availability of GeForce 6800 Ultra is limited and GeForce 6800 Ultra Extreme, frankly non-existent, though we can elucidate further on this.
The suggested 200 pieces of GeForce 6800 Ultra Extreme mentioned in our earlier story are very likely to be the projected limit of allocation to the likes of graphics overclocking meisters Gainward, and maybe new boy XFX, but we have also learned that very limited numbers of 6800 Ultra Extreme will be supplied to three particular US systems integrators who focus on the enthusiast and gaming markets: Alienware, Falcon PC and of course the really l33t Voodoo PC.
That said, samples of even Radeon X800XT are not exactly as common as muck, and it seems that apart from seemingly 'special sampling circumstances' by ATI's PR engine in Muenchen, the whole of the trusted UK Press has no more than two 16x pipeline boards to juggle between them all.
