7900 GTX works at 650 MHz

Nvidia can not raise the bar

NVIDIA'S flagship G71 won't be able to get to the speeds the firm wanted it to. We reported before that Nvidia needs at least 700MHz to beat ATI's R580 based X1900 XTX. However, according to our sources, the G71 will be nothing more than a 90 nanometre G70 die shrink. It won't have more than 24 pipelines but you never know what Nvidia has exactly up its sleeves.

It will use GDDR 3 memory running at 800MHz, with a 1600 MHz memory clock. In the case it ends up with 24 pipes it won't be enough to touch the R580, Radeon X1900 XTX performance crown. If Nvidia did put 32 pipes in G71 chip this would make its chip as a much better competitor and will make ATI run hard for its crown. We think that Nvidia could win most of the benchmarks with 32 pipes.

Nvidia plans to price its Geforce 7900 GTX very aggressively. That’s what you do if you cannot beat your competitor on the performance side. This card should cost $499 only and even the price indicates that the card won't be able to get the performance crown back. Last time Nvidia had a great card that managed to win all the benchmarks it priced its card at a saucy $650 and sold every single piece.

The cards should be sampled by the end of the month or at CeBIT. Nvidia will invite its loyal press, to Satan Clara to show them its new part. There will also be lower clocked G70 90 nanometre parts branded as Geforce 7800 GT and priced even less. Nvidia also plans to attack X1600 generation with its new 7600 GT, GS cards all scheduled for Cebit launch.

Remember, if G71 has 24 pipelines so does Sony Playstation 3. We will still sniff about it as some things are still unclear and G71 is more important to Nvidia that you can imagine. As long as it can ship millions of these chips at 550 MHz, a speed desired by Sony, Nvidia is fine. µ

after waiting all this time i will be sick if the card is a dog
 
right that's made my mind up for my next rig. Crossfire it is. Thanks for the post Baz. (Probably that is..)

I'm moving this into the Graphics forum too.

welcome to the dark side phill. ;) u wont be dissapointed.

I've not had an ATI system since the X800's - will be interesting to see how they have moved on.

A lot of people were speculating regards the G71 - it would seem that this is indeed a stop gap before the G80. Nvidia must be quaking in their boots.
 
I presume you need a crossfire enabled board for them? Silly question probably but i know nuthin of ATI? Otherwise i may have to give the g71s a run for there money ;)

VR-Zone reports 32 pipes - and that is what has been touted since the beginning - I would imagine that 32 pipes will happen.

Two other things to consider:

1) The 90nm 7900 uses less power than the X1900

2) Less power = less heat

After the X1800 Faux Pas, I would leave the decision until the reviews start coming in mate...... T-17 days ;)

Not a fanboi - just not convinced that the X1900 will be faster as it only just beats the 7800 512MB which is just a beefed up 256MB unit, SLI seems to be the better of the two multi GPU solutions right now also.

Yeah there's always the heat aspect - plus the fact the 71' may clock like the dogs choppers as a result. I'll see what happens, I'm in no rush. My 7800GTX is really beginning to struggle now though..
 
The whole idea is a stop-gap...with G80 here n a couple months, to me it looks like NV are doing now what ATI did with the X1800.
 
Since the 256MB GTX the new cards could all be classed as stop-gaps as mostly they are bigger clocks with no new features.

The X1800 was (I believe) born to cover the bad yield X1900 chip that failed to operate the 48 shader pipes and thus never made it to the XBox. So as to avoid that embarassment/cost etc the failed pipes were locked and they called it X1800, which also provided ATI with SM3 compatable card whic they desperately needed.

The 512MB GTX was insurance for Nvidia to ensure it has the fastest cards throughout 2005.

So now we should see the X1900 and 7900 series neck and neck and finally a real price battle should persue - hopefully making it a buyers market until X2000 and the G81 are released.

;)

ATI's new cards bring with it a DDR4 compatable memory controller - surely nothing short of development work for the SM4/Vista cards.

7900GTX is a die shrink of the current unit - with lower power/heat issues than ATI's, the bonus 'should' be 32 pipes.

All revisions of what's already available

yea, there ripping us off.

Edited by Kenny: swearing. Bad! :D
 
24 Pixels per cycle?? Are we to assume that means 24pipes??

MMMMMMMMMMMMMMMM - gotta tell ya this is less than ideal for the green machine if it is - having said that of course if it overlocks well, then it just might be enough.
 
Hmmm now I may actually stand a chance at staying near the top of the EPUK boards with the 7800GTX's I'm getting then :D

May pick up 2 more of em wen they get cheap and clock them to destruction :D

Boardy
 
would you ever consider offering an intel setup phil? not that I have the cash, but a water/phase cooled 955 dual core extreme edition chip, asus WS mobo and dual x1900 cards = pure sexiness :D

It also equals pure heat lol.
