Benchmark Restuls: DiRT2 Demo And S.T.A.L.K.E.R.: Call of Pripyat

AVADirect's W860CU: Mobility Radeon HD 5870 Vs. GeForce GTX 285M
By

DiRT2 Demo punishes the use of DirectX 11, giving non-DirectX 11 cards such as the GeForce GTX 285M a “performance advantage” for all the stuff they don’t render. In order to make the competition fair, we had to retest the Mobility Radeon HD 5870 using the game’s “Force DirectX 9” setting. The results for all tested settings are shown.

With both cards set to the same DirectX mode, the GeForce GTX 285M is only able to beat the Mobility Radeon HD 5870 at moderate detail levels and low resolutions. Both cards are fast enough to play the game at the panel’s native resolution, where the Mobility Radeon HD 5870 card edges out a win. Impossible for the GeForce GTX 285M, DirectX 11 slows the Mobility Radeon to a crawl.

Increased detail levels put the Mobility Radeon HD 5870 in the driver’s seat.

The S.T.A.L.K.E.R.: Call of Pripyat benchmark results provides DirectX 10, 10.1, and 11 modes, with the GeForce GTX 285’s highest level at DirectX 10. We retested the Mobility Radeon HD 5870 at DirectX 10, and found little loss of performance.

The Mobility Radeon HD 5870 outpaces the GeForce GTX 285 at all resolutions at the S.T.A.L.K.E.R.: Call of Pripyat benchmark’s Ultra preset, but we saw minimum frame rates that would make any of these resolutions unplayable.

    I must say I was under the impression that mobility graphic cards are similarly specced versions of their desktop counterparts & perform the same. Thanks to AVADirect & Toms for making me aware of my ignorance.

    Dirt 2 the full game has the benchmark feature at the bottom of the graphics options. You say it dosn't but I have double checked. Only diff is I run under XP.

    Simple logic was enough to figure out it isn't the case. A Radeon 5870 is 11 inches long, way larger than you can fit in a laptop. It generates significantly more heat than a laptop can possibly dissipate. And the big one: a laptop has to be able to run on a battery at least for a while. It can't power a desktop graphics card for any length of time...

    I'd love to see the industry forced not to be able to name COMPLETELY DIFFERENT HARDWARE - ie.e graphic cards for laptops and desktops, via the same name.

    'tis common sense.

    why? It's built on the same architecture. Thought it would be pretty obvious it's going to be a mild alternative considering the space it has to fit in. Portable gaming should be left to ignorant people anyway. Buy a DS

    I didn't see a mention of the max resolution of the two cards, the 5870 is the only of the two cards that can drive a 30" screen at 2560x1600 which is why i'm considering an upgrade.
