ATI Radeon HD 4890: Playing To Win Or Played Again?

Benchmark Results: Stalker: Clear Sky

Stalker: Clear Sky benchmarks are fairly new in our graphics card reviews, even if the game itself isn’t particularly fresh. Let us know what you think of this one in the comments section. At the very least, it’s a beautiful looking game. We measured performance by running the standalone benchmark and averaging together the four scores presented upon completion. Also, we opted for High detail settings, DirectX 10 lighting, and, in the case of the AMD cards, DirectX 10.1 disabled (for more on DX 10.1 versus DX 10, check out the page dedicated to that discussion earlier in the review).

At least at 1680x1050 and 1920x1200, the Radeon HD 4890 demonstrates its largest leads against the HD 4870 1 GB. However, that lead is needed in order for AMD to leapfrog the GeForce GTX 260 Core 216, which was faster than the Radeon HD 4870. Frame buffer clearly isn’t a huge issue here, given the performance differences between the 512 MB and 1 GB 4870 boards.

Frame buffer does make a world of difference with 4x MSAA and 4x MSAA for alpha-tested objects turned on. The 512 MB Radeon HD 4870 drops down to nothing, and even Nvidia’s GeForce GTX 260 Core 216 takes a significant hit versus the 1 GB AMD cards. The gap between the 4870 and 4890 remains roughly 10% or so. Most interesting, perhaps, is the Radeon HD 4870 X2’s pronounced advantage, almost exactly doubling performance at 2560x1600.

    i usually don't bitch and moan about them not having enough test gpu's, but i'd really like to see that sapphire 2gb 4870 up there, seeing how its in the same price range as the 4890...

    any of these cards would suffice for me, 1680*1050 does save you a pretty penny

    It seems to overclock well and outpaces the 275.

    The stalker results seem odd from both review sites. But stalker is glitchy.

    If priced right this should be a decent addition to the 4x series.
    It holds its own against the 275 and in certain games the 285.

    Perhaps sapphire will release a dual card.
    The 4850x2 they released performed extremely well.

    The 4850X2 is absent to compare to I see. Still nice to finally see a review of this thing. Nice gains over the 4870.

    any benchmark is welcome i suppose

    too bad price goes up exponentially for minimal improvements... the 4890 will be about %50 more than the 4870

    Both the 2 GB card and the 4850 X2 are exclusive to Sapphire, and neither has been sent over. Nevertheless, we'll be following up with SLI/CrossFire scores in the near future and I'll see if either of those two solutions might be lined up for that story.

    cangelini, you are the man.

    just thought i'd let you know. this article was very well written, and you said everything i was thinking including the pricing. too bad you have to go to the other article to refer to gtx275 comparisons. regardless of that, gj

    Thanks Ek. Truth be told, both companies pulled their launches in, allowing about a week to get the testing/writing done. Usually that's pretty tight for one new launch. Two is a little rougher. But hopefully there was enough cross-linking between the pair to convey the right messages.

    I'll post it here as well as in the GTX275 review:
    Summing all the framerates is just nonsense. ;-) The games with higher fps will weigh more than the others.
