Application Performance & Power Usage with SYSMark 2004

We start out with SYSMark 2004's Internet Content Creation suite, and from a performance standpoint all three chipsets perform within the margin of error for this benchmark:

SYSMark 2004 - Internet Content Creation Suite

Power consumption however is a far more interesting graph than performance, as there is a clear difference between the three chipsets.  Intel's P965 comes out on top (in a good way), with the system drawing an average of 127.1W, followed by the 975X with a 2.5% increase in power usage and finally NVIDIA's nForce 570 SLI at 138.1W.  While the difference between the P965 and 975X isn't too great, NVIDIA's nForce 570 SLI draws an average of 11W more than the P965, or 8.6%.

Given that all three platforms perform the same, the performance per watt graph isn't very alarming - the lowest power consumer gets the best performance per watt.

The Office Productivity suite in SYSMark 2004 has the nForce 570 SLI slightly underperforming, with the P965 weighing in about 4.5% faster, but still nothing significant.

Once again, it's the power consumption charts that are the most interesting; with a lighter CPU load, the power consumption of the platform manages to stand out more and here the nForce 570 SLI uses 11% more power than the Intel P965.

Performance being virtually equal, the performance per watt graph tells us exactly what we expected to see:

    The test in theory would be beneficial, but the article doesn't state exactly how or what was really measured.

    Not a very useful test then, flawed from the get go.

    This is no way to measure chipset power consumption. Two deluxe boards with 8-phase power versus one mainstream board with a mediocre 3-phase power system.

    The gains in 8-phase vs. 3-phase is enough to explain the difference we're seeing here.

    Perhaps measuring the generated heat of each chipset could tell us something, but this is useless.

    Perhaps little component difference can make it up, but I doubt it. I've seen other power consumption benchmark which show that Intel chipsets consume the least power: http://www.goodwin.ee/sulo/Power2.htm">http://www.goodwin.ee/sulo/Power2.htm

    Interesting quote:
    One interesting thing that somewhat suprised me when testing K8 and P4 boards. P4 chipsets actually consume the least amount of power. VIA chipsets which have two chips besides the integrated northbridge come a very close second, but most surprisingly, Nvidia nForce 3 chipset, with its one sole chip beside the integrated northbridge, actually consumes a whole lot more than all the others. Especially on boards which use linear regulators to feed the northbridge. My own Chaintech VNF3-250 with a low power videocard consumes almost 50% more from the 3.3V rail than Intel branded i865 board with integrated video (which consumed 10W from 3.3V rail using a single 512MB DS stick). MSI branded KM800 board with integrated video came very close to Intel board though (also with a single 512MB DS stick).

    Don't get me wrong, I prefer intel chipsets by far. I'd especially like to get my hands on the P965.

    BUT!

    As it says in your quote: "linear power regulators". Those that just waste whatever voltage difference there is are by far the cheapest. So would it be surprising to find such regulators on a motherboard that is half as expensive (give or take) than the other two? I think not.

    the onboard power regulation and conditioning is very important, and will become ever more important with lower and lower chip voltages, as the current increases.

    Awesome, but take a look above again. Nforce 570 SLI, is lower power than Nforce 4 SLI, which is still higher than P965 and 975X.

    Not only that, we see Nvidia's chipset just suck in terms of power consumption.
  • Plantemanden - Saturday, October 14, 2006 - link

    Yeah, perhaps you're right.

    Though they should really check the voltage of the cpu with a multimeter. There is an uncertainty on the voltage to the cpu, that could easily make up the 5 or so watts

    Look at this: http://www.gamepc.com/labs/view_content.asp?id=c2d...">http://www.gamepc.com/labs/view_content.asp?id=c2d...
    P5B is even lower than P5B Deluxe

    Then this:
    http://www.techreport.com/reviews/2006q3/foxconn-g...">http://www.techreport.com/reviews/2006q3/foxconn-g...

    Looks like other P965 chipset boards can do even better than P5B.

    With Nforce 570 SLI board included. Asus P5NSLI with Nforce 570 is 3-phase, and the P5N32-SLI SE Deluxe with Nforce 4 SLI chipset is 8-phase, but the Nforce 4 version consumes more power. I guess 3 and 8 phases aren't that big of a difference. The Gigabyte version mentions Quad Triple Phase with "virtual 12-phase" but the Foxconn with 3-phase(http://www.tomshardware.com/2006/05/22/six_975x_en...">http://www.tomshardware.com/2006/05/22/...ds_for_t... manages to achieve the lowest power consumption too. What's up with that?? I guess its because Intel chipsets do consume less power, and Nvidia's consume a lot in general.

    Isn't it also strange how nobody else but Intel documents their chipsets so detailed?? I can't find ANYTHING in Nvidia/Via/ATI/SIS site for their chipsets other than the "product brief/overview etc".

    Im sorry guys but this is lame. I usually love your articles but this one is useless to me. I mean we are talking maybe 8% difference between chipsets? Thats almost margin of error. Besides, its not like we are talking 300W per chipset here.

    I guess I was expecting more.

    Thanks
  • ATWindsor - Friday, October 13, 2006 - link

    10 watts diffrence just from chipsets is quite a lot IMHO, its about as much as a harddisk, and can be a real considiration in a quiet and/or low-power setup (combinde with cooling soution of course).
  • raymo - Thursday, October 12, 2006 - link

    Your data and graphs are misleading. You have 1 part in 1000 information you have logged on performance and power. When you have a ratio, that ratio is still accurate to 1 part in 1000. Instead, you truncate the graphics to 1 part in 100, and lots of things look the same. This is wrong!
