AMD Radeon HD 7870 And 7850 Review: Pitcairn Gets Benchmarked

Benchmark Results: MediaEspresso, Luxmark 2.0, Bitmining

If these numbers seem vaguely familiar, it’s because we saw them once before in our Radeon HD 7700 series launch. After emailing back and forth with the helpful folks at CyberLink, we established that, at some point, AMD had pulled a couple of DLLs from its drivers, preventing MediaEspresso from utilizing hardware-accelerated encoding.

Now we see that support for accelerated encoding is available again. However, performance does not change.

It’s insane that we were able to test this feature and demonstrate its benefit more than a year ago when Intel’s second-gen Core processor first launched (Intel’s Second-Gen Core CPUs: The Sandy Bridge Review), and it’s now completely broken in multiple successive driver builds for some reason.

We use LuxMark to help evaluate the compute potential of AMD’s Radeon HD 7000-series cards, and our findings with the 7800s confirms GCN’s strengths in this discipline. The Radeon HD 7850 is the fourth-fastest card in AMD’s new line-up and it beats the Radeon HD 6970, last year’s top-of-the-line single-GPU flagship.

AMD’s Radeon cards are the favorites for Bitcoin miners. Although the 7800s continue outpacing anything from Nvidia, they don’t overtake the 6900-series cards. It’s probable that the client’s implementation of OpenCL differs from LuxMark’s.

    Wow..7870 has nearly half the power-draw of GTX 570 and performs better . IMO this is the most impressive card in GCN line up so far.

    AMD saved the best for last it seems. Although a bit over priced, these cards are amazing performance/watt with all the new features. Nice to see the 7870 take a few blows at the 580 in a few games. Can't wait to see what kepler can do as well!

    impressive performance of 7870 (i was disappointed by the 7770's performance )And what about microshuttering? Is it present in 7870 CF?

    Looking at the performance graphs, 7870 performs very close to 7950 which has 40% more SPs and a 384 bit memory interface. I think AMD reduced the performance of 79xx series on purpose so that they can release a better card just before the launch of Kepler.

    the 7870 is quite impressive. O.O almost the same gaming capability of the 580 for 350. OMG!

    It is there in the first page. "you won’t be able to buy the card until at least March 19th, AMD tells us."
