Encoding Performance & Power Usage with DivX/WME9

In our DivX encoding test there's about a 10% gap between the Intel 975X and NVIDIA's nForce 570 SLI, with the P965 falling in line closer to its older brother than NVIDIA's offering.

Power consumption is as expected, with the P965 consuming the least and the nForce 570 SLI consuming the most.

The performance per watt chart has the 975X and P965 tied, thanks to the 975X's higher performance.  And given the nForce 570 SLI's lower performance and higher power consumption, it falls to the bottom of the chart.

Windows Media Encoding has all three platforms equal in performance:

...and power consumption is very similar to our DivX test:

    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?

    The power consumption aspect is obviously only one part of the decision to go with a particular chipset


    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.

    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.
