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.

    Yes at the moment AMD is most definitely getting top dollar for these Vid cards just as Intel does all of the time on their CPUs - until they have competition.

    In case you didn't notice the new 7xxx series cards surpass Nvidia's current offerings in just about every category so this IS a step forward in performance at the same or lower prices.

    Hello,
    Does anybody know if those two cards would work in crossfire? The Crossfire compatibility chat is not yet up to date and I can't seem to find that information anywhere....

    Hd6870 and gtx 560 can be had for 160 and 165 respectively. WHY would anyone want the SIGNIFICANTLY slower 7770? It's not like it's directX 12 or something. Reply

    I can understand why so many get it wrong but I can also clearly see.

    7770 currently retails for $169.99 - $179.99

    6870's currently retail for $189.99 - $209.99 original price was $249.99

    I just checked these numbers from 3 retailer

    7770 is a weaker card then the 6870, sure but performance per dollar is actually a little better with the 7770. Considering the lack of competition from Nvidia why would AMD reduce the price to performance ratio that exists. AMD is selling you more features for a better value card.

    When Kepler arrives AMD price's could go down if Nvidia prices it that way. If Kepler is all the #$%^ it's hyped to be AMD will counter it with a price drop then we all win. Looking at ATI/AMD's history something they have always offered the customer, superior price/performance of the competition.

    AMD will always be better price to performance for less while Nvidia justifies there inflated prices with CUDA, PhysX, TWIMTBP and of course better driver support.

    The value of performance will remain as is. Like a commodity on the stock exchange, why would Nvidia devalue there own stock or at least so quickly?

    I checked the prices I listed on newegg just before posting that. Not sure where you got your prices from, but shop newegg in the future... that way you aren't wrong :p. Reply

    There is something REALLY odd about 560 TI numbers on ELDERS SCROLL V.

    Under 7770 REVIEW it shows 7770 right above 550 TI and on the top of all them is a standard GTX 560 with like 46 fps and here, on this review it shows the GTX 560 TI with like 36 fps. The settings look just like the same..

    Please correct that because it is looking like the GTX 560 TI is worse than the 7770, wich it isnt by at least a mile.

    With a 7770 the power consumption is below that of the Radeon HD 6870 and GeForce GTX 560 Ti, while still delivering the same gameplay experience of those video cards. About 2%-7% slower then 560 Ti. Reply

    My 5850 still server me well @ 1600x900 res.. Not until these prices drop i'll upgrade..

    AMD is obviously maximizing profit with these products, seeing that Nvidia next launch is at least 2 months away...

    Price wars, really?

    seriously, 250$ for a low end video card and 350$ for a mid range video card, not even the MAIN LINE serie but somewhat weaker versions of their 7900 serie counterpart.

    Video card markets have been ripping off consumers in the past years with their super hefty high prices.

    it should be like that: 150$ for new low end video cards, 250$ for new mid-range and 350$+ for whatever they want to sell to whoever will always buy the most expensive stuff no matter.

    the price of the 6800 should all be below 100$ right now and the 6900 serie prices cut in half .
