Bioshock

AMD's RV770 GPUs absolutely demolish in Bioshock, the Radeon HD 4850 is nearly as fast as a GTX 280 and the 4870 is close to the speed of a GeForce 9800 GX2.

    It scaled more than 100% in a few games?
  • DerekWilson - Wednesday, June 25, 2008 - link

    greater than 100% scaling is due to margin of error combination for both single card and dual card tests in the vast majority of cases.

    we also tested single card performance on an nvidia system and crossfire performance on an intel system, so the different computers will also add margin of error.

    two card solutions generally don't scale at greater than 100% except in extraordinarily odd situations (where rebalancing loads might help with scaling on both individual cards -- but that's odd and rare).

    Why no 260 and 280 SLI?
  • ImmortalZ - Wednesday, June 25, 2008 - link

    Because, with that kind of money, one can an entire system with one 48xx :P

    Also, page 10 appears to be broken.

    No 260 or 280 SLI in the benchmarks, but they included them in the power charts. Odd.

    The power data was simply taken from the GTX 280 review, we just added to the list.

    As for the GTX 280 SLI numbers, we didn't include them as it it's mostly out of the price range of the Radeon HD 4870 ($1300 vs. $600 for two 4870s). We can always go back and redo the graphs to include them if you guys would like, but in the interim I would suggest looking at the GTX review to get comparison numbers.

    Take care,
    Anand

    we actually only have one GTX 260, so we can't test that

    Yes, and the click to enlarge doesn't work.
    And believe it or not, posting right now from a AT page that looks like 1994...!

    Insert a buy in there. Need edit!

    but can it play crysis?
