Power Consumption

As this is NVIDIA's first 65nm part, it certainly of interest to see how it stacks up to the current line up in terms of power consumption. NVIDIA quotes the max power of the 8800 GT as 105W, but in the real world, we aren't just stressing the GPU. Let's take a look at system power draw under 3dmark 06 (specifically the pixel shader test).

Total System Power Consumption


Total System Power Consumption


The 8800 GT draws less power than anything that competes with it in terms of performance. When G80 hit last year, we made a big deal out of how power related to performance. This card simply blows everything else away in terms of how much little power is needed to attain incredible performance.

8800 GT SLI does draw more power than the 8800 GTX, but it also performs much better in cases where performance scales with SLI. For those who want high performance, power is generally less of an object, but it's good to know that 2x 8800 GT cards won't break the bank like a pair of 2900 XTs in CrossFire.

    Yes it has VP2 processor for video decoding. But why would you need a fast gaming card for HTPC? Wouldn't 8400/8600 be a cheaper/cooler solution? Reply

    Thanks for the reply.
    This card looks to be pretty cool running and when not running 3D intensive apps I'm sure power consumption and noise is really low.
    So it might be nice to be able to play a little on a 52"LCD!

    also, if you go with a less powerful card for HD HTPC you'll want at minimum the 8600 GTS -- which is not a good card. The 8800 GT does offer a lot more bang for the buck, and Sparkle is offering a silent version. Reply

    Nothing like cherry picking the games... I don't understand why games like Stalker and Prey weren't tested as the 2900XT has superior performance on those titles, as well as other titles. Seems like a biased test. Reply

    They didn't test The Sims2 or DeerHunter either... Reply

    lol ... stalker and prey?

    we tested quake wars, which is effectively updated prey (id's engine).

    and stalker runs better on nvidia hardware -- when tested properly (many people use demo flybys that point up at the sky way too much rather than fraps run throughs).

    Hmmm I thought ATI's RV630 and RV610 chips both support PCI-E 2.0? Reply

    Yeah but it's not worth mentioning because theses GPU are not from nVidia. Reply

    The G92 is fabbed on a 65nm process, and even though it has fewer SPs, less texturing power


    G92 has the same amount of SPs and MORE texturing power (twice as many addressing units) than G80. However, 8800GT card has some SPs and texture units disabled.

    well, first, if G92 has those units disabled, then it can't claim them.

    second, NVIDIA would not confirm that the G92 as incarnate on 8800 GT has units disabled, but it is fair to speculate that this configuration was chosen to work out yields on their first 65nm part.
