Radeon HD 7950 3 GB: Six Cards, Benchmarked And Reviewed

By published

With Nvidia's GeForce GTX 670 readily available for $400, AMD's Radeon HD 7950 shifts to the upper middle class of graphics card performance. We test six third-party interpretations in anticipation of pricing more in line with its competitive position.

Temperatures

We chose three different loads to use for measuring thermal performance: idle, gaming, and full, with the latter testing using open and closed cases.

As you might guess, the more aggressively a fan spins up in response to load, the more noise it makes. We'll be able to make a comparison on the next page, where we present the acoustic benchmarks.

HIS' HD 7950 IceQ Turbo and Asus' HD 7950 DirectCU II boast two of the most extreme cooling solutions in this round-up. That's made evident in our results, since both companies finish in first and second place with regard to thermal performance. HIS' cooling solution shines under load and in a closed case, which is a testament to the effectiveness of its DHE design. And remember, it manages to excel while monopolizing only two expansion slots, while Asus requires three.

The PowerColor HD 7950 PCS and the reference design finish in the back of the group. We're expecting PowerColor's card to consequently be one of the quietest. On to the acoustic tests!

    in some of the earlier charts, gtx680 is written as "gtx 680 1536MB".

    also, gtx580 seems to be missing in the crysis2 charts.

  • Just thought you might like to know that the x-axis captions for the noise level graphs are labelled as they would be for temperature, rather than decibels

    That nvidia turbo boost is a bit cheating and you should turn it off for the test. It's basically same as overclocking and your review sample cards are most likely binned to get much better than average OC.

    Nice article. Glad to know I'm not missing much by sticking with brand loyalty.

    Why was there no expanded information on the overclocking ability of the GPUs? Half at 1025MHz and Half at 1050MHz doesn't help anything.

    As well, what kind of memory overclocks did you get? Did you have to change the voltage of the GPUs to get said clock speeds?

    This article was missing a bit too much info there to really be able to get the full picture of these GPUs. The HD7970 6 card shootout is how it should have been done for the HD7950s. Each cards overclocking ability (core/memory) and what they got with stock voltage and overvolted.

    WOW.
    how is it cheating? it is cheating only if the average user will not use the "GPU boost" feature, but reviewers are using it.

    and, the card is faster, cheaper and cooler than the competition. so if you are better, you cheat?Fanboi.

    XFX HD7950 didn't make the list?

    You know what this is like? Imagine yourself as a concert prompter, trying to put a lineup together. You have Megadeth, White Snake, Poison, Guns -n- Roses, AC DC, you think you're doing just fine...What? Metallica wanted nothing to do with that roundup of Who's Who? Did they turn you down, or did you guys turn them down?

    Because XFX matters. XFX always matter! And I'm pretty sure they weren't scared to step into the ring and beat some heads in with a comparo with the best in the biz. You guys need to get in touch with them and test their HD7950 and see if their card has the potential to blast that "elephant in the room" and hang it's head on the wall.

    This is Tom's Hardware after all...

    I really like the charts posted for the benchmarking! Gives a much wider range of cards.
