Power, Heat and Noise

Power Load

To test the power load of the card, we measure the total watt usage of our test computer at the wall outlet, recording the power usage of our system in two different states. The first state is with the card installed and the computer is idle, and the second is during intensive performance tests (looped Splinter Cell benchmarks). This way, we are able to get a general idea of how the power usage varies between cards.

Heat

We also wanted to see how much heat these cards generated. We found that the EverTop 6800 GS generated the least amount of heat by a wide margin compared to the other three. The unique HSF design of this card may contribute to its low level of heat.

 Graphics Card  Temperature
EverTop GeForce 6800 GS 56 C
EVGA e-GeForce 6800 GS 64 C
PNY GeForce 6800 GS Overclocked 67 C
Leadtek WinFast PX6800 GS Extreme 69 C

Noise

We were curious to see what kind of noise these cards generated as well. What is interesting here is that, similar to our heat tests, one card stood out among the rest. The EverTop GS was by far the most quiet of these cards, again perhaps due in part to the radical HSF design. The fact that it is the lowest clocked of these cards also plays a part here. The EverTop is the only card to use a non-reference HSF. Obviously, the Zalman fan, though bulky, does a better job of cooling the card while it keeps quiet. Below are the noise levels for each card.

 Graphics Card  Noise Level
EverTop GeForce 6800 GS 45.9
PNY GeForce 6800 GS Overclocked 50.1
EVGA e-GeForce 6800 GS 50.5
Leadtek WinFast PX6800 GS Extreme 50.7

For reference, the noise level of the room with the system off was 39.1.

    Sometimes people are shocked by this, but there are people out there who are buying new computers these days. Not everyone is in the market for an upgrade. Of course, we care about the upgraders as well, but everything needs to be in its place.

    I have a feeling there's something on the horizon that will make all the agp lovers happy. But that's all I'm gonna say about that.

    The 6800 GS for AGP isn't much more than the PCIe versions and I'm curious to see if performance was similar just like the 6600GT. And to all those that just throw AGP to the curb: I still run an A64 3200+ on an MSI nForce 3 platform. Why am I going to replace it with a nForce 4 mobo when socket M2 is basically around the corner? Remember, I would have to pay $100 more to get a PCIe mobo with the GS which would cost more than just getting the AGP version.

    when something generates a lot of heat it does NOT mean it is hot. An vice versa.

    Actually the amount of heat is clearly visible on power consumption graphs.

    The "heat" graph actually measures the efficiency of cooling solution, not the heat produced.

    Otherwise APG version seriously lacking as many have allready pointed out.

    Yeah. I particularly stumbled over this sentence on page 9:

    "We also wanted to see how much heat these cards generated"

    - right after the nice power consumption graph that showed exactly the same power usage, and thus they must produce exactly the same amount of heat. No way around thermodynamics.

    The sentence should have read something like: We also wanted to see how hot these cards ran. (which is how well the cooling solution is able to remove the heat)

    I have the eVGA 6800GS. What I didn't expect was just how LOUD it was.
    In 2D, originally used RivaTuner to turn down the fan to a minimum (was barely tolerable), but had to keep the loud mode for 3D. In the end bought the ArticCooler NV 5 Rev 3 without even knowing if it fits (it was either that or return the card). The AC isn't silent by any means, but much quieter and as a bonus a cooler solution. It however takes up a second slot (exhausts hot air behind the case - another nice bonus)
    Even with the card being cooler by the AC, the OC seems to be limited to the low 500s for the GPU.
    The mem on my card seems to be an exception, with no artifacts even at 1300 (650 DDR).

    I would like to see how this card does DVD amd HD acceleration, for HTPC use, non gaming. I want to replace the noisy 6600GT and this could be the right card.

    Great article AT thanks for doing the job I want to, but can't, do. You guys are a great part of the tech business and are doing the public a service, free of charge to your users. I can't ever complain about that and thank you. BUT,

    Early in the article you mention that the X1300 or the 6200 card would be plenty of power to run grannie's computer for $50 - $75. Why does the recommendation for this type of computer keep increasing? Not that long ago everyone was saying an MX200 was plenty for Mom, now we have to the latest GPU family to run Outlook? Most Intel MB reviews state that the IGP is fine for Aunt Virginia and it is free (basically). I just wonder where the cutoff is on 5th generation spreadsheet graphics rendering. Until there is some increase in graphics complexity in MS Office I can't see the need to buy anything other than an IGP board for the purposes mentioned.

    Yes, I have heard that Vista is gonna smoke the cheap cards, so maybe now is the time to increase the minimum power standard, but will it keep increasing from there? If a card can run Aero at release does the GPU recommendation ever need to be changed until Aero does?

    If I am wrong please let me know so I can track the necessary changes in the future. Uncle Delbert needs a new box so he can find out what all this Pr0n stuff is, he's been hearing about at the Sunday meetin'.

    Just trying to embarrass myself on a highly public forum, you may officially start laughing at my views now.

    This is a good point, actually. The kind of card that would be "good enough" for granny is a very subjective thing, and depends greatly on the person's needs. People who just used the computer to write in offive or use spreadsheets probably don't need a graphics card at all. That said, as software advances, better hardware acceleration will probably be required, but it need not be confined to the $50 to $75 price range.

    I basically feel the same way Josh does ... In fact, I was going to write a nice quick blurb like that, but it turned into a crazy rant that I posted in the forums.

    I can get a bit long winded sometimes. Mostly I'll just delete the intended comment and walk away, but I think I'll start making forum posts in the future.

    Thanks,

    "AGP is dead which is why it wasn't tested."

    then why aren't they giving them away free then? fraud fraud fraud on nvidia i tell everybody

    the title didn't say only "The NVIDIA 6800 GS [PCI-Express] Closer Look: EVGA, Leadtek, PNY, and Evertop"

    thanks to the authors of the article though
