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

Benchmark Results And Overclocking

3DMark 11

It barely makes a difference if a Radeon HD 7950 is clocked at 880 MHz or 900 MHz in 3DMark 11. Compare to AMD's reference 800 MHz, however, and the distinction is much clearer.

All of these boards lose to Nvidia's GeForce GTX 670, though, even though HIS' HD 7950 IceQ Turbo almost manages to catch up to it in Crysis 2. Unfortunately, four of these six boards cost more than the $400 GTX 670, hurting their value proposition against the competition.

Crysis 2 (DirectX 11)

Overclocking

We overclocked each card as much as possible without increasing their voltage settings. Half of them managed to hit 1050 MHz, while the other half maxed out at 1025 MHz.

Bear in mind that doing this pushes power consumption into Radeon HD 7970 territory, though performance is also able to exceed a GeForce GTX 670 in Crysis 2. HIS' HD 7950 IceQ Turbo even manages to edge out the GeForce GTX 680 by two-tenths of a frame per second. The caveats, of course, are that the GeForce-based cards were running at their stock frequencies and that factory-overclocked versions of those cards are already available, too. Moreover, Crysis 2 is a game that scales well with GPU clock rate, and it's known to work well on AMD's hardware. Titles like Battlefield 3 and DiRT 3, which favor Nvidia-based board, instead show the GeForces on top.

    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.
