Power Consumption And Temperature

Nvidia GeForce GTX 460: The Fermi We Were Waiting For
By

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?

    "Again, this is just a teaser. We’ll be following up with a full exploration of these cards in SLI, comparing them to a GeForce GTX 480."

    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...

    guid_aaa000001I have never waited for this... It's not "we", it must be "some people".Note: That is if you consider "me" in that "we".


    We, as in Tom's Hardware ;-)

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

    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.
