There still may be hope....


Anyone else thinking that maybe these news sites are posting the 7900GTX only hase 24pipes to get hits...?

[walterman]

So, that's why the card is $100 more expensive today than yesterday :D

[FPS3lusive]

Yea well you know how may hits these internet sites are getting by saying the 7900GTX has only 24pipes... probably in the 100's of Thousands. Seems like nvidia has had no problem in the past makeing cards that are faster then ATI's no matter the cost to the consumer. Unless they had a plan to make the 7900GTX with 32 pipes from the beginning, And after seeing what ATI was going to delever. They decided to just keep the 24 pipes insted of 32, and beat the X1900XTX. Maybe 32 Pipes would have Pwnt the X1900XTX To Much? and they only wanted 5-10FPS more to keep the market in there hand, and keep there Title. With minimal production costs? Either way I dont see NVIDIA giving away the Proformance Crown until the G80. Hence the 7800GTX 512, which was basicly a hype lanuch.

Sense when is Nvidia concerend with being price competivite? thats what the GT sieres of cards are for. Generly hasnt the Top end GT/GTX cards in the past had more pipes then just mem/core clock differences. And how would Nvidia Dubble Folting Point Proformance with a -150Mhz mem drop and a +100Mhz Core Boost. "The documents from NVIDIA also indicate that GeForce 7900GTX will be "twice as fast as previous generation chipsets" in floating-point performance - Dailytech"

I doubt Nvidia's Top End card will retail for $499. Prices Generaly Go up not down. Altho I wouldnt be opposed it they drop....

I have a tendency to believe chinese sites over US ones.. being thats were the cards are made. In any case I want to see the 7900GTX with 32 Pipes. But I guess time well tell in a week or so we will see some real cards.


Here is a little number brake down based on

http://www.dailytech.com/article.aspx?newsid=915

7900GTX Assuming 512MB

655MHz core frequency
256-bit memory interface
Memory Bandwidth (GB/sec) 52
Fill Rate (Billion pixels/sec) 15.0
Vertices/Second (Millions) 1450
24 pixels per cycle

7800GTX512

550Mhz core frequency
Memory Interface 256-bit
Memory Bandwidth (GB/sec) 54.4
Fill Rate (Billion pixels/sec) 13.2
Vertices/Second (Millions) 1100
Pixels per clock (peak) 24
RAMDACs (MHz) 400


Brake Down

7900GTX vs 7800GTX

Vertices Vertices/Second (Millions) +30.19% +350 Million
Memory Bandwidth (GB/sec) -.047% -2.4 GB
Fill Rate (Billion pixels/sec) +1.8% +1.8 Billion
Core Frequency +105Mhz
Core Memory -150Mhz

Dose This Hold True? "The documents from NVIDIA also indicate that GeForce 7900 GTX will be "twice as fast as previous generation chipsets" in floating-point performance - Dailytech" Or dose it Seem like the 7900GTX would need 32 Pipes to Dubble Folting Point Proformance. Or do they mean Previous Chipsets as in the 440MX :P

Who's Gona Calculate avg Frame Increase?

Anyway Iam done Ranting for now, Someone respond.

[mikechai]

7900GTX is 24 FP period.

[walterman]

There's only one doubt for me. In those 'specs' you can read '24 pixels per cycle'. Ok, it could mean 24 pipes, but, it also could mean the number of ROPs, cause the ROPs handle the task of converting fragments into pixels (doing MSAA if needed). Anyway, at 650MHz it should have the same FSAA (about ROPs) performance like in R520/R580. So, i think that we can expect a nice boost here.

[FPS3lusive]

Yea Hopefully they mean ROP's....

According to the famous gibbo on the overclockers uk forums, these cards are not going to come cheap. Around the £330 for the 7900gt and £450-£500 for the GTX.

Omg! :scarey:

I love nVidia cards to death, but god damn do they jack prices like no ones business on their new cards. I call extortion.

[CaptNKILL]

Heh, its looking more and more like an x1900xt for my next upgrade...

I really want to stay with nVidia, because its familiar and works really well, but if they cant beat out the x1900xt's performance with a card in the $400-$500 range, they lose this round, and Im converting.

Releasing things at the $600-$800 pricepoint doesnt make a whole lot of sense. You'd think they would just release a bunch of faster cards at a competitive price points so people actually have a reason to buy them over ATI cards.

Its all speculation though... I think we'll probably get some better leaked info in the next week or two, but after March 9th we'll know for sure what they are doing.

Dont worry i am in the same boat. I dont really care if the 7900's are 5fps faster they have to match the xt in price. Heres hoping its all speculation.

This guy aint got a clue. I've just set my allocation and pricing up with BFG and this guy is miles out. All I will say is 7900 GTX and 7900 GT aint cheap and 7900 GT won't show until end of March.....
From these prices 7800 GT and 6800 GS won't get replaced straight away and will fit in with the current lineup as 7900 GT is quite a bit more than 7800 GTs etc.....

[SigmaOrionis]

Do the review sites already have these cards? Then right after March 9th when the NDA lifts the reviews will be up?

[walterman]

That's crazy ! Around 480E for the GT & 730E for the GTX & without 32 pipes !

Where're the benefits of the 90nm here ? It should bring us cheaper chips or chips with more gates. Not only a 100-200mhz clock increase only from previous 110nm chips.

/agree

It seems there are about 3 people who can afford nVidia cards anymore and jakUp is one of them. The bleeding edge of video gaming is starting to bleed the coffers of gamers, but they will pay.

[Superfly]

still waiting on the Q4 '06 GPU's to go with my nice new copy of Vista!!!

[NoWayDude]

Any new card in the UK is a RIP OFF.U do not need to go to Overclokers to get your stuff.Normaly they are more expensive than other sites, and yes, they do the usual price gouging.Besides, u should not thrust evrething u read in the Internet :)

European prices for 7900 GTX and 7900 GT emerge

"The Geforce 7900 GTX 512 card is set to cost €549 in Europe. Some partners, however, plan to price them higher." -> (€549 = 650$)

"It has 24 pipelines working at higher clock from 7800 GTX 512 speeds and that’s about it."

"The Geforce 7900 GT is set to cost around $299 in the US but Europeans will be able to buy this card for a more realistic €329." -> (€329 = 350$)

"We know that Nvidia is ready to ship some 7900 GTX at launch day - we heard that 7900 GT will be available a few weeks later."

Well, seems like the GT will be the wise option, if you're into overclocking.

[shabby]

Theres no way a 7900gt would be half the price of a 7900gtx, i dont buy that.

[walterman]

Well, check the prices of the 7800GT (300€), the 7800GTX (500€) & the 7800GTX512 (700€) in Europe.

After going x850 to 7800GT SLI, I’m not going back to ATI for at least 2-3 years, I can't stand their drivers. And I’m sure 7900s will be faster and priced competently.

no offense, but vista isn't that nice.

I was never that great at math :P

With the 7900GTX at Fab90 Have any ideas if this should be more flexable for Overclocking?

Id like to see them at Core 725Mhz/Memory MHz1750

I think if the process does include low-k, then I see 725Mhz to be very possible, especially because Nvidia was always very conservative when it came to clocks. And I remember Victorshen (http://www.nvnews.net/vbulletin/showpost.php?p=817581&postcount=21) said in one of the other 7900 threads, that sources told him that it isn´t too difficult to reach 800Mhz. Your best bet is to wait until the card is reviewed or until others post about their overclocks.

[NoWayDude]

There is no 90 mm without being low-k
