Overclocking: Gaming & Compute Performance

As always we’ll keep the commentary thin here, but overall the overclocked performance of the 7800s looks very good, which is what you’d expect with a 15%+ core overclock and a 12% memory overclock. With the exception of Skyrim performance at 19x12, the overclocking performance increase for both cards is roughly split between the core and memory overclocks, meaning we’re seeing a 13.5% average performance increase for the 7870 and a 17% average performance increase for the 7850. As the 7800 series has the same number of ROPS as the 7900 series, it looks like we’re running headlong into the memory bandwidth bottleneck that makes the 384-bit memory bus on the 7900 series sing.

All things considered among our tests we have everything from even the 7850OC beating the GTX 580, to the GTX 580 still holding onto its lead versus the 7870OC. But even if you can’t beat a GTX 580 with a 7870OC you can get very close on a card that costs a good bit less.

Meanwhile for compute performance the gains are similar: 12.5% on the 7870, and 19.5% on the 7850.

    Metro 2033 (the highest settings bench)

    Radeon 7950 33fps
    Radeon 6970 27.5fps

    Radeon 6870 32fps (the second highest bench)

    Weee!!! $400+ for 5.5fps more.

    Not sure about you, but to me, spending that kind of cash for an imperceptible increase in performance is having no sense of money's worth.

    This generation of cards can safely be skipped until the 8xxx/7xx series from both AMD and NVIDIA.

    Picking up one specific benchmark to underline your point. Great reasoning skills, you should join a debate team! Also, that 5.5fps is still 20%, with the good track record of overclockability, it can reach as much as 40%. But you stick to your point.

    What? were you expecting me to post a powerpoint presentation for just for you??

    The numbers are there, look at them if you want, but hey, be stuck in your point, only a frustrated basement geek can think in way to justify spending $400 +/- for less than 50% increase in performance.

    Be careful of not falling of that horse, seems pretty high.

    Please check the avg frame rate improvements, not some specific results. But everyone agrees that 7xxx cards are a bit overpriced and that's because they don't have competition right now. If you worry about power consumption, buy these cards now. Or more interested in price/performance, wait till Kepler is released.
  • arjuna1 - Tuesday, March 6, 2012 - link

    I can agree with that, after Kepler is release prices will go down and maybe then the 7xxx series will increase in the perceived value.

    If there's no competition then they aren't overpriced because they cannot be touched by anything, hence making their price absolutely correct !!!
    I call that "reality".
    If Kepler blows their doors off, their price will fall. That's reality too.
    It's time for all the amd is cheaper crud to go the way of the dinosaur.
    Recently a 460 was an unbeatable value. Then a 560ti was as unbeatable value. Currently a 6870 is an unbeatable value.
    These things happen, and a deal is not the general aspect of the video card prices, which generally speaking wind up right where they should be.
    The deal is the exception to the usual rule across the board, and "the deal" as in "big price drop" is usually just one card here or there for a short period of time.

    Radeon cards have been coming out at $700 and $600 and $500+ for a long time man - even with competition.
    I don't know what planet you people come from when the constant repetition of "it sounds good" becomes an absolute meme and ongoing restated theme but in no way reflects even a tiny kernel of truth as far as reality goes.

    Yes dagamer34, Ryan praises amd for drying up their 6000 series channel with such precision. Then we get this praise - the perfect price structure by AMD, and "it's conservative pricing" according to the author even though it's $40 and $30 higher than it's Nvidia counterpart...
    " With AMD targeting the ~$320 570 and ~$210 560 Ti and given their conservative pricing on the rest of Southern Islands, it should come as no surprise that the 7800 series is priced equally conservatively. The 7870 will have an MSRP of $350, while the 7850 will have an MSRP of $250. With the 7800 series completing the launch of Southern Islands, this gives AMD a consistent price structure for the entire family: $550, $450, $350, $250, $159, and $109."
    ---
    I see. So more expensive is conservative, and the 6 AMD price figures are perfect and consistent...
    I am so sick of it...

    Thus far, AMD's first foray into 28nm graphics has been unimpressive. From a price/performance standpoint, the 7000 series has not given the usual incentives for upgrading that is regularly associated with the move to a new node. I hope a strong competitor from nVidia is on the way, as that would bode well for consumers such as ourselves. As it stands, the 7000 series lacks value except at the very high end, where price/performance is of little concern.

    Price vs. performance is not the only factor, some people are concerned with power draw as well. Others are interested in temps, and noise. The price could use some work (come on Nvidia) but besides that the 7xxx series has been fairly impressive in regards to overclocking, power, temp, and noise.
