AMD Radeon HD 7870 And 7850 Review: Pitcairn Gets Benchmarked

Test Setup And Benchmarks

Today’s story is going to be a little different than what you’ve seen from us in the past. The Radeon HD 7850 that AMD sent our US office was so unreliable that it wasn’t usable in a vast number of benchmarks. More on that when we break into the individual tests. AMD wasn’t able to get us a working replacement, so much of our performance data comes from Tom’s Hardware DE by way of Igor Wallosek. The result is that we have two different test systems.

    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.
  • ilysaml
    Watch the benches well, the HD 7870 almost beating the GTX 580.
  • alex3064
    what date is this 7850/7870 actually launched
  • esrever
    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!

    alex3064what date is this 7850/7870 actually launchedi mean when will it be launched in market

    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!
  • hardcore_gamer
    alex3064i mean when will it be launched in market
    It is there in the first page. "you won’t be able to buy the card until at least March 19th, AMD tells us."
