GeForce 7950GX2 Details, Preliminary Benchmarks

_JP_ disse:
O Zarolho...à que não esquecer que a board dele em SLI é 2x8 e não 2x16.
Os drivers ainda são Beta.
E para terminar, ele tem um cpu que apesar de bem rapido, não é dual-core. E toda a gente sabe que que os dual-core para SLI têm bons ganhos de rendimento.
Aquilo está limitado pelo cpu e não é pouco...

Huumm...Ele não anda muito longe deste tipo no XS, com um Opty 165@2700mhz 1:1 + 7950GX2 XFX XXX 570/775 (single card).

Agora este, com um Yonah sim...Já são scores de registo!

card on stock cooling, stock volts, oced to 604/768 for all test...

Quad SLI numa board 2*8 PCIe... e num cpu single core..
Não admira que tenhas melhores scores em dual do que em quad. Com tantos bottlenecks no sistema era de esperar..
O teu sistema está completamente entupido com, na prática, 4 PCIe lanes por cada GPU.. ainda por cima com um single core a fazer a distribuiçao do SLI..

Gostava era de saber que drivers estás a usar.. são os que vieram no bundle? É que toda a gente diz que os últimos da nVidia não dão para quad (nem os últimos nem os anteriores..).


Para aproveitar bem um quad-sli só mesmo um conroe puxado ao máximo ou um conjunto AMD 4x4..




Se queres um conselho.. vende uma das 7950GX2, o FX57 e muda para um opty 170/175. Mesmo que não passes dos 3.2Ghz no overclock, vais ver um aumento no desempenho em vez de uma diminuição.

«...about 3 months ago i tested this in some vendor's lab.... 7950GX2 with very old driver... the score was bad bad.....
i thought it is not going to beat the 7900GTX....
well.... but i am wrong with Nvidia.... their software/driver team.... best of the best..... can't believe it...


CPU: INTEL E6700 @ 3.6G
VC: XFX XXX EDITION @ 620/775
RAM: GSKILL DDR2 800 @ 1000
MOBO: INTEL 975XBX
COOLER: TOWER 120
POWER: 1KW PC POWER and COOLING

well.... for single card..... strong!!!!
for QUAL.... sorry no mobo lol!!!
the TEMP under full load is about 85C...
wonder it is inside the case and playing some Q4,Fear, FC...etc after 1 hr...
they need to put some better heatsink... man it is $600+.. i want some thing like copper not cheap alu...»

Nvidia bans 7950 GX2 Quad SLI testing


IT IS a kind of a secret that Nvidia asked all its partners not to send out two 7950 GX2 cards to reviewers.

Because the reviewers might tumble the fact that using the two cards in a Quad SLI setup just won't work.

The graphics firm told its partners that the driver is not ready yet. Even if you you are lucky enough to buy or get two cards they simply won't work together, at least not yet.

There is no timelime but the 7950 GX2 Quad SLI driver should be available soon. Red-faced Nvidians are surely beavering away on it as we speak. We will let you know when we hear more about the issue.　Nvidia does want to make things right this time.

For the time being, you will have to hold your breath on Quad SLI 7950 GX2 cards, so don't dash out and buy a second one. Not yet. µ

EVGA e-GeForce 7950 GX2: report

Just today I received two EVGA e-GeForce 7950 GX2 for testing. First impressions are following:

1. Card pwnz
smile.gif
And main reason is not the speed itself but possibility to work on ANY PCI-Express-compatible motherboard, not only NF4/NF5x0 SLI series.

2. Speed is just a bit faster than two 7900GT in SLI mode. Of course, GTX SLI is still the fastest due to much higher clocks.

3. Without proper airflow through case, card is quite hot. But not hotter than mentioned above GT SLI combo. But with open side panel and humble Coolink 120 mm fan (just 65 CFM) core temperature don't rise over 72C during testing.

4. Overclocking is not that bad. From stock 500/600(1200) MHz one of my cards reached 600/775(1550) MHz in conditions described above. The other one is still untested, I'll report later. For SLI solution with awful cooling system it is nice achievement, as for me.

Now regarding the results. These are results for plain review which I'll publish today/tomorrow on ModLabs.net. So no voltmodding, no CPU overclocking, no cooling modifications - NOTHING EXTREME AT ALL

Testbed specs:
AMD Athlon 64 FX-60/Asetek WaterChill/Foxconn NF4SK8AA/2x512MB HyperX @ 2-6-3-3-2T/Seagate 300GB/Creative X-Fi Platinum/Hiper Type-R 580W/Win XP Pro SP2/ForceWare 91.29 beta

EVGA e-GeForce 7950 GX2 (500/1200) vs. EVGA e-GeForce 7950 GX2 @ 600/1550 vs. 2x EVGA e-GeForce 7900 GTX @ GT (450/1320)

3DMark 06: 7797 - 7648
3DMark 05: 12372 - 12350
3DMark 03: 28702 - 28288

Information about overclocked 7950 GX2 performance, as well as comparison with 7900 GTX SLI combo will be added in an hour...

Quad 7950 driver to come at the end of summer

NVIDIA announced its 7950 cards and as we said it will brand these as a single card rather than an SLI double, double jeopardy. Those ones are really putting ATI's X1900 XTX cards under pressure, especially because of the very low price. But there is still no driver that can make two of those cards work together.
And it turns out that there is more than that.
Nvidia won't release a Quad SLI capable driver as soon as we all hoped. Geforce 7950 will get its Quad SLI by the end of the summer. Don't kill the messenger for bringing this upsetting news but a chap from Nvidia confirmed this to me yesterday.
Just as Nvidia announced SLI and then it took its time to finish its driver it will need time to finish the driver for four cards. No conspiracy theory - the green company just wants to do things right.

Só ter Quad SLI no fim do Verão é bastante banhada (tipo o Verão acaba quase em Outubro)

A motivação de quem compra placas destas com certeza que envolve o Quad SLI

Deviam ter feito este lançamento duma maneira mais organizada
 
nVIDIA 7950GX2/7950GX2 SLI (QuadSLI)

Final Words

After an extended period of using these cards, the only thing that we can say that single card prices will give X1900XTX a BIG run for its money, although you might think that this product wasn't ment to compete with it. The ATI X1900XTX is priced just a little bit lower, and the 7950GX2 proved to be a lot faster. It was not unexpected, as the card uses two GPUs, but we have to admit that NVIDIA surprised us all with the retail price of 7950GX2. Because GX2 uses SLI technology, the driver is very mature and there were no problems on this end if you use one card. If you are looking to spend around €500 to €600, look no further, because currently this is the fastest product on the market, and with a very competitive price. Since we were able to benchmark QuadSLI as well, we have to comment on that technology as well. Frankly, with all of the warnings from NVIDIA we were skeptical, but it turned out to work quite nicely. The drivers probably still need a little work in terms of correctly assigning the frames to the GPU for rendering, but the SLI AA modes work rather well as is.

De certeza que a nvidia nao lanca ja um driver que suporte quad sli pk esta a espera da resposta da
ati para a geforce 7950GX2 :-D

Realmente é estranho. Qual será a versão dos drivers que eles usaram? Não consigo ver isso identificado em lado nenhum na review, nem nas imagens em que provam estar a conseguir usar o quad-sli.

JP,
Obrigado mas ja tinha experimentado, ate agora sao os melhores, no ecra mostra quad-sli mas os resultados sao melhores em sli. 1 placa so.
Obrigado a mesma.
Nota: ja usei o driver da 7900gx2 mas pior resultados..

Mais uma resposta de outro fulano da XFX.
[TONY - 2006/06/07] Hi, it is still a very new product, officially quadsli support is only for system builders, but here is a new driver specifically for the new dual-gpu models : ftp://www.xfxsupport.com/public/driver/91.29_XP_MCE_2000_forceware_intl.zip. Thanks Tony

Porque não experimentas mandar um mail ao gajo do it-review.net a perguntar que drivers ou que método é que ele usou para conseguir pôr aquilo (aparentemente) a funcionar. Pode ser que ele te dê uma mãozinha e logo ficamos todos a saber se é "doable" já, ou não.

Estranho.
Esse 91.29 do link nem é o driver mais recente.


Já existe um 91.31 no Guru3D:
