Nvidia GeForce GTX 460: The Fermi We Were Waiting For

Power Consumption And Temperature

At idle, all of these cards do fairly well. The only outliers are the two GF100-based boards, which use about 10W more than competing GF104- and Cypress/Juniper-based cards.

Under load, however, it’s painfully obvious that the highest consumers of power are GF100-derived boards. AMD’s Radeon HD 5830 interestingly comes in third, followed by Nvidia’s first GF104-based card, the GeForce GTX 460 1 GB. The 768 MB version of the card uses 18W less under load. And of course, AMD’s Juniper-based Radeon HD 5770 is quite power-friendly.

Not surprisingly, there’s a relationship between power consumption and maximum temperature. Somewhere in there, also, is a maximum tolerable fan speed that each company can use to keep temps down.

The really surprising thing here is that, even though the GF104-based cards aren’t the lowest-power in our review, they operate at the coolest temperatures and do so using remarkably-quiet fans. In fact, there wasn’t much difference between the acoustics at idle and under load. AMD’s Radeon HD 5770 is comparable in that way; however, its load temp is notably higher.

Compare the GF104-based cards to the GF100-based boards—the difference is fairly staggering.

    Finally, the price wars from the 4000/GTX 200 ages are back!

    Tamz_mscAt last, Nvidia has impressed me(to a certain extent).But where's power consumption in SLI?

    Did you even read the whole article?

    Great review as always, Chris.

    Very nice SLI scaling IMO...That is one department where Nvidia wins always...
    Hope to see ATI improve their scaling performance...And a very good article there Chris...

    Nice review, Chris. Best I've read here in a while.

    I have never waited for this... It's not "we", it must be "some people".

    Note: That is if you consider "me" in that "we".

    the 5830 i think is a better card, hell you can get a 5770 super-clock it and thats the same speed as a GTX460 for a fraction of the price!

    Might have overlooked that line, but I'm wondering how the 460 would perform when overclocked.

    Comparing it with your test on the 480 , two GTX 460 1gb s in SLI does seem to outperform a single 480, although very slightly

    Took them long enough. Bring on the price wars.

    I hope they this will make the price war trickle up to the higher ati and nvidia cars. have had my eye on a 5850, hope the 5830 get real cheap fast and the 5850 to follow down to the $250 price range.

    i wonder if they will make a new gtx465 with the a full or near full gf104 core.

    this is a decent budget card, but this disgusts me. If nvidia really wants to make us wait 6 months after ati, they might aswell made it the extra couple of months for the 480 to be put on fermi 104. i cant believe they didnt wait

    This is the same GPU as the laptop GTX 480m isn't it? Same GF104?

    Funny comparing a supposedly more powerful card (GTX 460) against the 5770 and it still makes the 5770 look good due to less power, cheaper price, and of course the (relatively) small difference in FPS where it would make a difference (anything over 60ish FPS is not counted).

    actually, i like ati and all, but id take the 460 1 gig version over the 5770 anyday, way more bang for buck

    Just checked with Guru3D, these cards easily overclock to 800+ MHz core without voltage tweaks.An absolutely great overclocker!

    yeah, same here, i saw this thing get past 850 on default speed stock cooling.
