Gaming Performance & Power Usage with Quake 4

At 640 x 480, we're not GPU bound at all so power consumption isn't nearly as high as it could be, but performance is.  In theory this configuration should be stressing the chipset more than anything when it comes to power usage.

Quake 4 Performance (640 x 480)  

The P965 continues to be the lower power solution, with the nForce 570 SLI drawing over 6% more power on average during the course of the benchmark.

Obviously the winner of the performance per watt test is the P965, by a reasonable margin thanks to its higher performance and lower power consumption.  But what happens if we crank up the resolution to a more GPU-bound setting?  Will the differences in chipset power consumption get larger or smaller?

Quake 4 Performance (1280 x 1024)  

At 1280 x 1024 there's no longer a performance difference between the three platforms since we're very GPU bound, but let's see how power consumption changes.

The gap between the P965 and nForce 570 SLI actually grows to 8.5%, and obviously giving the P965 the performance per watt crown.

Let's look at a few other titles before coming to any conclusions though.

    The days of ATI building chipsets for Intel CPUs may be numbered, but I'd be interested in seeing how their current offerings compare to nVidia and Intel.

    Also, how does integrated graphics change the power equation?

    I would never consider power consumption in choosing a chipset. Two or three watts of pwer consumption isn't even worth spending any time considering imho.

    yeah the same to me, I think for the average user power consumption of a chipset will never be a primary criteria when buying a new MB/platform. For the enterprise/business customers..that's another matter. These mbs here in the test were for the average user though.. I don't see what's with all the fuzz on performance per watt(power consumption) issue lately, at least when the differences are so minor..
    I'm looking forward to a thoroughly investigation on core 2 duo platforms..till then, keep up with the good work Anand..you are still my best:)

    For those wanting power consumption data on older chipsets that support C2D, which also includes consumption at idle, http://forums.silentpcreview.com/viewtopic.php?t=3...">See here

    Yep, don't care about power consumption of the chipset. Also, if you're looking at business machines for 10,000+ users, you aren't going the custom build route as the costs to build aren't worth the savings on parts. You're going to go with a canned solution and most of those machines have low power draws anyways (no fans, low wattage power supplies, bare bones components).

    Guys if you don't care about chipset power draw then why bother reading the article (assuming you even did) and why even bother replying to the forum?!? Sheesh.
  • Madellga - Friday, October 13, 2006 - link

    Dells and HPs (canned solutions) also use those chipsets. There are "canned" workstations also, for CAD work for example. They are not barebones, although cheap components could be used.

    Low wattage PSUs do not translate in lower consumption. A 500W rated 80% at 100W consumes the same as a 300W rated 80% at 100W. Most likely the canned PSU will be a cheaper one and consume more.

    Corporate purchases are Global Sourced and they go for the cheapest. No corporate buyer will pay a cent more on every computer to have an Enermax PSU, for example.

    Wrong. Can you imagine in a office?
    In a large corporation, or gov. office, that has more than 10000 computers.
    That's a lot of money.

    If you think worldwide, that's a lot of energy. You don't pay this out of your pocket, nevertheless it is money wasted that could go somewhere else.

    In the long run, it's also contributing to Global Warming and other pesky effects.
  • yyrkoon - Friday, October 13, 2006 - link

    Except that a large corporation wouldnt be using this type of otherboard most likely to begin with.

    I have to agree with the OP, in that a few WATTS is no big deal here, however, CPU / GPU power usage can be, and often is.

    I know that one thing is for sure, IF I ever use SLI, its going to be a mid ranged card that uses much less power, as I dont feel that 1 KW is nessisary for hight end PC (which is how much future PCs are going to be needing at this rate).

    In a COLD country making little use of air conditioning, the excess power consumption from pcs would actually warm up the office and SAVE MONEY AND ENERGY in building heating costs. Also the electricity might be nuclear or green, whereas the building heating is more likely oil or gas (fossil fuels being depleted making green house gases and co2).

    If you live in say Texas or the Sahara desert, it would of course increase your aircon costs.

    Anyway I was interested in how the 590 chipset performed against 570 in power consumption.
