nv40 2x faster than nv35

[fantomas]

xbit labs posted this yesterday....reprinted at 3dguru (http://guru3d.com/) ....

The representative from the Santa Clara, California-based company said the NV40 would be twice as fast as the NV35 and would feature entirely new architecture.

When do you think NVIDIA NV40 will be announced? I suggest that roughly a year after the NV30 at Comdex Fall 2003 in November. The graphics cards itself will in this case come either in very late December or in early 2004. Note that in the second quarter next year Intel rolls out its Grantsdale platform with PCI Express-based connection for graphics cards, so, it is logical to assume that either NVIDIA NV40 already features PCI Express or NVIDIA will release another NV40 architecture GPU with the support for new bus in the second quarter 2004. And that may be already the NV45, coming out six months after the NV40 in mid-2004, I assume.

a few thoughts about that rumour...

2x faster than nv35... at what? clock speeds are twice as fast? or 2x as many 'points' in 3dmark??

pci express is going to be even more useless than 8xagp, since nv40 is likely to have around 256mb RAM anyway.

And so the hype begins. Hopefully NV40 will live up to the hype better than the lackluster NV30 did.

How come I ain't really inclined to believe any of the hype out of nVidia until they can produce?

Two times as fast as NV35...

Hmm, NVIDIA/Huang once stated that NV35 would be two times as fast as NV30...

nvidia claims NV35 is twice as fast at shading as NV30 is...which is of course BS as far as I can tell.

it might be 2x faster in certain extremely controlled circumstances which technically would support the claim... and therefore will be blown out of all proportion by the PR department...

so it is correct in so far as you understand WHAT it is correct in lol...

I have yet to see an example of these controlled circumstances. Without any empirical proof, I will call those claims lies.

Well, the only thing I see substanially improved over the NV30 is the shader performance which was suppose to double anyways. But what I don't get is why the 5900U is so close in what are suppose to be memory bandwidth limited benchmarks (AF/AA) to the 5800. There's nearly double the bandwidth! There has to be quite a bit of performance waiting to be released in some new drivers.

IT's 2x as fast eh? Is the nv35 turned on?

[CaptNKILL]

Bah, im not really concerned with this card. I mean, sure its gonna be faster than the NV35, but its going to be out MONTHS after Deus Ex: Invisible War, Half-Life 2 and Doom 3 (assuming those are released on time). And who wants to wait?

If I upgrade, its going to be later this summer, so I have the power to crank up the settings in HL 2 :D

For NVidia's Sake... Lets hope they thrashes ATI's offering. NVidia had a bad time with the NV30 and everything. Hopefully, they learned their lessons and create a better product. Rite now, I am hoping for better af/aa quality.

Um...the gfFX5900 IS significantly faster than the gfFX5800 with FSAA + AF turned on. It's 50% faster with 4x FSAA(most bandwidth limited benchmark), and 20% faster with 4x FSAA/8x AF(AF is influenced primarily by fillrate)! Keep in mind that the gfFX5900 is clocked lower than the gfFX5800 too.

And it is almost twice as fast at shader ops than the 5800 is. It's a much better computational tool as well, maybe because they have dropped FX12 support and concentrated on optimising FP support.

[Uttar]

In *optimal* conditions, with little register usage that is, the NV35 is 98% faster than the NV30 ( can't remember whether that was per-clock or assuming retail clocks, though ) when running FP16/FP32 ( but in FP32, you're really gonna have to use 1 or 2 registers to have that though )

Too bad those "optimal" conditions are rarely reached, making the R3xx beat the hell out of it in most cases.
