Benchmark Results: S.T.A.L.K.E.R.: Clear Sky

ATI Radeon HD 5870: DirectX 11, Eyefinity, And Serious Speed
By , Fedy Abi-Chahla

Right off the bat, it’s clear that the Radeon HD 5870 is a fast card. It hangs close to the Radeon HD 4870 X2. However, a GeForce GTX 295 killer it is not—at least not in this first measure of real-world performance. Bear in mind, though, that this is a single GPU going up against ATI’s former dual-processor flagship, along with Nvidia’s dual-GPU champion.

When you shift the comparison to the GeForce GTX 285, ATI stomps the single-GPU board at all three resolutions. With the GeForce GTX 285 currently selling for as little as $340 online, though, ATI does make you pay a premium for the card's additional performance and functionality.

Clearly, S.T.A.L.K.E.R.: Clear Sky is off-limits at 2560x1600 for most of these single-card configurations (though the two 5870s and GTX 285s handle that setting with Extreme details set). Nevertheless, gamers with 24” monitors should have little trouble cranking up to 1920x1200 with the image quality settings turned all the way up in this demanding title.

The rest of the field sets the stage for the arrival of ATI’s Radeon HD 5850, which wasn’t ready for testing at launch, but should follow shortly. Expected to still out-perform the GTX 285 at an incredible $259 price point, that card might end up defining the performance sweet spot.

When we turn on 4xAA, ATI’s efforts to improve anti-aliased performance shine through. Whereas the Radeon HD 5870 trailed the 4870 X2 previously, it’s now the faster offering (albeit only slightly).

But if you’re talking single-card configurations, none of these boards will really do the trick with such an intense combination of settings. Even at 1680x1050 the Radeon HD 5870 can only muster 36 frames.

Where you will witness utter dominance is with a pair of 5870s, which slingshot past the Radeon HD 4870 X2 and GeForce GTX 295 (as expected, given the price difference), emerging as the only solution capable of these settings at 1680x1050 and 1920x1200. Even the two GeForce GTX 285s in SLI are handily trounced.

    So it looks like 1 is enough for me.. Dont plan on getting a 30 inch monitor any time soon.

    Looks like the NDA lifted at 11:00PM, as there's a load of reviews now just out. Once again it shows that AMD can produce a seriously killer card...

    Crysis 2 on an x2 of this is exactly what I'm waiting for.

    I refuse to buy until the 2GB versions come out, not to mention newegg letting you buy more than 1 at a time, paper launch ftl.

    Thanks for the timely review. I have to say though, some of the technical details are beyond me. It'd be useful if you explained terms such as "VLIW architecture" or "tessellation engine"

    Oops, who am I kidding ? I just ordered 2 5870's. One Sapphire, and one HIS, seeing as how they limit you to one per customer.

    I think most of this review has to do with how many games are optimized for nVidia. The Crytek Engine 2.0 and Source Engine are well known for heavily favoring nVidia architecture yet compose the bulk of the benchmarks. I think the fact ATI can do best in these engines when they have a detect ATI instant nerf its performance speaks measures for the actual card.

    Another thing is that the 5800x2 isn't out yet, now think of two of those bad boys in Crossfire.

    Not bad for Crysis benchmark. I really want 5870 for my christmas present, but damn I also need to buy a new PSU.

    In addition, I am impressed that the 5870 has a better power consumption and better gaming performance compare to DX10 cards. If the card is affordable I'd definite buy one.

    Jasper,
    TBH, the architectural details are secondary to how the card performs. However, if you'd like a better idea of what tessellation can do for you, check out the picture of the Alien on page six!
