Nvidia's GeForce 8800 GT Reviewed

Power consumption, noise, overclocking

Power consumption

power consumption G92 benchmark

Strengthened by the 65 nm process, the GeForce 8800 GT displays interesting power consumption levels; it’s slightly lower compared to an 8800 GTS 320 MB (we win 18 W when idle and 13 W under Age of Empires III, after subtracting the PSU’s losses). We’re still much higher than the GeForce 8600 GTS and, therefore, higher than the consumption we may have hoped for a mid-range card, if manufacturers didn’t have the wicked pleasure of increasing consumption on their cards entire range with each new generation, but the performance/watt ratio is still increasing, which is a positive thing, especially considering the number of transistors in question. When considering those results, the 105W value given by NVIDIA for the total consumption of its card, seems to be credible.

Noise level

Using a sonometer placed 2.7 inches away from each card’s fan, we measured the noise after disconnecting the CPU’s fan (only the PSU’s discreet fan was on).

noise level G92

Of all the cards tested, the MSI version of the GeForce 8600 GTS is the noisiest with its double slot cooling system (that doesn’t slow down in 2D), followed by the HD 2900 XT whose blowing noise is really dreadful in 3D. After that, we enter discreet grounds, and the GeForce 8800 GT still walks a flawless path by still being as discreet as, if not more so than, the other GeForce 8800. Its fan is only noisy for two seconds when the PC is turned on, but noise never increased during games.


There’s small disappointment on this level given the expectations that traditionally come with a smaller process. Our GeForce 8800 GT still saw its GPU clock go from 600 to 680 MHz, a 13% increase, the stream processors following a similar pattern. Memory wise, we went from 900 to 1050 MHz (+17%). In the end, the improvement with Age of Empires III in 1920 x 1440 reaches 11%. It’s nothing exceptional really, but we must keep in mind that the G92’s clock is extremely high originally and at 680 MHz, we obtain a computational power superior to that of the 8800 GTX!

    ah well, the 2900 pro (OC'd to xt) was still a good deal *tries to comfort himself*

    8800 GT puts the GTS in an bad price market now and not so smart buy now

    8800GT looks like a real good midrange performer FOR THE MOMENT. I would not invest any money in a videocard upgrade, there are NO proven Dx10 cards out there. I would wait until Vista is sorted out and there are more than a `handful' of Dx10 games out there, otherwise you are just buying very poor attempts to deliver Dx10 performance on your PC.
    If I really, really had to get a new card right now, it would be the 8800GT!

    From my point of view as a more budget gamer, I hope that these new upper midrange releases push down the price of cards like the 8600GT and 8600GTS. I'm also very noise concious with my computers and it's good to see that the already relatively quiet 8800 series has contined in the same way.

    I think it looks like a great opportunity for the owners of DX9 cards to comfortably come into the DX10 world. Still it is not that magic that will make me consider dealing in my 8800GTS 640MB - saving my pennies for the big fish early next year.

    Seriously what did ppl expect? that gfx cards will stand still in time and not advance forward, with vista released i don't think microsoft will let hardware like the 8800gtx/ultra to sit at the top at a premium.

    Since vista i trying for the masses they need hardware which can decently run it for the masses and priced for the masses.

    Its good news for tech ppl etc who know the value from this, but how many ppl just want a computer that can play games decently and not cost a fortune? thats right everyone.

    The tech has to advance like for win98 to winxp, everything takes time and the time has come for this.

    It excellently, undoubtedly this best. What is similar it is possible to find on Fileshunt.com
