That happens to be 14% more clockspeed

Hmmmm, yes....this is all very confusing so far.....guess we'll have to wait and see.

I'd trust Denny's results except a MARKETING ploy is low-balling him, so idk what to think.

partners comparissions are the same as manufacturers just numbers, sometimes are reals and sometimes are fake.

Those would be mine!

How is the angle-independent anisotropic filtering, Denny? Noticeable image quality improvements?

The pic is fake. 430mhz * 1.14 is exactly 490mhz. The pic just shows the Asus 7800GTX 490mhz card, the "8" in 7800 is changed to "9".

Here is eVGAas 470/1200 MHz 7800gtx/256 card:

And the 490/1300 MHz:

Both are 256 MB variants.

110nm @ 18.65 x 17.9 millimeters

Therefore, if transistor count is still 300m, we have G71 at:

90nm @ 18.65 * (90/110) x 17.9 * (90/100) millimeters

= 15.3 x 14.6 millimeters

I dont think something like that will ever exist anyway, because ram will probably be a lot smaller, and something like that would probably cook the insides of your PC.

I think thats a 3dFx card

7900 GT specs and Pics.

European prices for 7900 GTX and 7900 GT emerge
http://www.theinquirer.net/?article=29871

**Starscream** · 02-23-2006, 05:55 AM

if them prices are correct then they could sell nicely even if their not more powerfull then the x1900xtx.

**krille** · 02-23-2006, 06:30 AM

Anyone think there'll be an Ultra version coming or why all these rumours about 32-pipes? Or would that be the G80 (since it's not unified shaders afterall it seems)?

MSRP on 7900GT(X) is dirt cheap though. I still wonder if there aren't any more differences than mfg process, since there earlier was talk about higher IPC seeing Denny's benchmarks and ofc additional features (angle-independent af etc).

**Shadowmage** · 02-23-2006, 06:42 AM

Seriously, if MSRP is "dirt cheap" as you say, there's only one possible reason: performance. It either ties or doesn't come close to X1900.

As for proof of my statement, just look at 7800GTX 256MB (when unopposed) and 7800GTX 512MB (inflation!). NVIDIA loves charging exhorbinant prices when they're in the lead, and I don't blame them for doing so.

i,
OK I have been given some real information about the new Nvidia 7900 and it's exactly what I have been saying all along. The G71 appears to just be a speed bumped G70 with just enough performance to win back the NV crown in most games. IQ is unchanged making the X1900 still IQ king and in shader intensive games the X1900 XT-X will still win out and be far more future proof with games later this year.

As you can see price wise the 7900 GTX is around the intial price of the 512 GTX which IMHO was very over priced. This to me makes the XT-X a real bargain and a no brainer.

Specs

7900 GTX
24 pipes
650 core
1650 memory
Selling for approx £450 +VAT

7900 GT
24 pipes
450ish core
sub 1400 memory
Selling for approx £300 +VAT

Enjoy

It will be very hard to get high enough yields to make 32 pipes profitable. I think Nvidia is just making a cheap GPU this round (it's smaller than the G70). I see no way that Nvidia could ever make a high clocking 32 GPU with this "new" 90nm process. They are probably just going to clock it higher than the G70 and that's about it.

If it is only a speedboost of 100MHz on the core there is no way it can win back the crown.

Whoa...what happened to 32 pipes !!??

the same that happened with the 24/32 pipes of the R520
just speculations

**GoriLLakoS** · 02-23-2006, 08:06 AM

What about some Dual 7900 Powah???

**Vapor** · 02-23-2006, 08:08 AM

That's a beauty GoriLLakoS...wow

**Marioace** · 02-23-2006, 08:08 AM

is that similar to the quad SLI of the CES

**GoriLLakoS** · 02-23-2006, 08:10 AM

Don;t know...i spot it on a Japannese site at he morning....and now i can't find it again....!!

I did't even copied the specs...

That is SO disappointing. I had put my hopes into this G71. Guess X1900XTX it is then... and for CF I would have to buy a new mobo - again. Great!

So I take it no angle-independent AF then?

**perkam** · 02-23-2006, 09:32 AM

Remember though..that its on 90nm tech...meaning higher oc's

and that we have to be more carefull with our voltmods..
they are easier to fry..
