Performance in Semi-Synthetic Benchmarks

Futuremark 3DMark06

The non-overclocked Radeon HD 4890 is a little faster than the GeForce GTX 285 in terms of general score as well as in the individual groups of tests. When overclocked to 1000/1200 (4800) MHz, it even challenges the dual-processor Radeon HD 4850 X2: the gap is a mere 85 points in the SM3.0/HDR tests.

We minimize the CPU’s influence by using the Extreme profile (1920x1200, 4x FSAA and anisotropic filtering). We also publish the results of the individual tests across all display resolutions to provide a full picture.

The overclocked Radeon HD 4890 even beats the Radeon HD 4850 X2 in 3DMark Vantage, but the GeForce GTX 285 with its hardware and software PhysX support is better yet. The gap is only 300-350 points, though.

The new card enjoys the biggest advantage over the Radeon HD 4870 1GB at 1280x1024. When overclocked, it is faster than the Radeon HD 4850 X2 at 1280x1024 and equals the latter at the higher resolutions.

It’s different in the second test: the Radeon HD 4890 is ahead of the Radeon HD 4870 1GB in every display mode. When overclocked, it can only catch up with the Radeon HD 4850 X2 and GeForce GTX 285 at 1920x1200 and higher resolutions.
