NVIDIA GF100 & Friends speculation
- Thread starter Arty
- Start date
300W TDP
Does no one care for PCIe stickers anymore?
If this trend continues @ Moore's law's pace, how long do you think will it be before GPU's evolve into ENIAC's shape, diet and size
I think NV can't make dual-fermi on 40nm,so they need to push GTX480 clock as high as possible...300W TDP

Well, a 3GPC chip with 32 rops / 256bit memory interface by all accounts could be as fast as gtx470, if they can get clocks up a bit.
I'm not sure how this needs to be done, but certainly GF100 can already do this somehow, how else would 32 cores be disabled? In fact with GF100 it's more strange as it results in a asymmetric chip.

The benchmark is done using a dual core CPU running at 2660MHz , 3D Mark06 is CPU sensitive .
We are not going to have cards where the TDP is essentially equal to the max power available on the line. Come on guys....I know things are bad but a little common sense never hurt.
That same CPU achieves a similiar score with an overclocked GTS 250. Granted that card has more TMUs and probably a much higher clock than the 470.

Ignoring the nonsense overall score and looking at the individual tests, GTX280 scores higher:And a 5870 would be nearly 20% faster with a similar cpu.

Another (credible) source for those gtx470 benchmarks / clocks:
http://www.heise.de/newsticker/meld...ung-der-GeForce-GTX-470-enthuellt-946411.html
1255Mhz shader clock
800Mhz gddr5 (base) clock
They say though specs are not final (specs should be final next monday).

Why are you so sure of this? This can be a reasn why a single rail supply is being recommended.
That 3Dmark06 score came from a random poster at PCI, probably fake.
heise.de (in german) has new information about the GTX470:

Probably not, but does it really make a big difference whether it's 280, 290, 299 or 300W?
I'm not. Hence the common sense bit. There's simply no precedent and that scenario would have zero headroom.
edit: actually what's the TDP on the GTX 295? Is it 290+? If so, then yeah ignore me...
http://www.nvidia.com/object/product_geforce_gtx_295_us.html
Maximum Graphics Card Power (W) 289 W
And for the HD 5970:
http://www.amd.com/us/products/desk.../Pages/ati-radeon-hd-5970-specifications.aspx
Maximum board power: 294 Watts
If the GTX 470 is really that close to the HD 5850, then it's a disaster of epic proportions. If true, it will barely be faster than the GTX 285.
I would wager that the 470 should be closer to the GTX 295 and not the GTX 285, but if not, then this is definitely not looking good.
A new architecture that brings almost no performance advantage over the previous generation, is definitely a flop.
Still, some of the numbers posted are very fishy. I would like to see someone actually "credible" with some leaked benchmarks. It's wait and see.

Nope it's 289W
Though it exceeded it in practice. Maybe it's much closer to the truth this time - kinda like what AMD did, the 4870X2 also exceeded its TDP, whereas the 5970 does not.

I know, and as I wrote, with the same cpu, a little OC'ed 5770 could have made that score - the 57x0 shows a similar difference in the scores, unlike most other cards of that range (eg. existing nvidia cards scores more in SM2 and less in SM3).
And ofcourse we should just look at SM2/3 scores and not the even more cpu dependent overall score.
Wouldn't be so sure. The Unigine numbers for the 4xAA scenario are the same as the chinese site posted earlier, with the addition of the HD 5850 numbers, so this seems to be just an extension of what the chinese posted before.
