NVIDIA GeForce GTX 580 Barely Faster than GTX 480 at Same Clock Speeds
One of our forum members asked us if we could run the GeForce GTX580 and GTX480 video cards at the same clock speeds to see what happens to performance. The reason for this is that you will be able to see the performance boost created by just the extra CUDA cores and the new architecture enhancements on the GeForce GTX580 video card. Our reader wanted to see what the performance boost was on Metro 2033 as that is the game he was interested in. We are more than happy to do benchmarks for our followers when they ask and the results were very interesting.
We are seeing a 1.33 to 1.66 FPS increase with just the extra CUDA cores, which translated to just a 3.5% boost in performance in Metro 2033 at 1920×1200. It looks like going from 480 to 512 CUDA Cores is minor and that the bulk of the performance boost is due to the higher clock frequencies that the card comes with. NVIDIA claimed up to a 30% performance increase and we saw a 31% increase in 3DMark vantage, but in real games the most we saw was 18% during the testing we did in our review. What are your thoughts?
The GeForce GTX 580 GPU delivers the world’s fastest performance for DirectX 11 (DX11) games, and support for NVIDIA 3D Vision, Surround, PhysX, SLI and CUDA technologies, further entrenching GeForce-based PCs as the most robust gaming platforms in the world. The combination of an innovative vapor chamber thermal solution and new architectural enhancements make the GTX 580 the fastest and quietest GPU in its class, delivering an increase of up to 35 percent in performance per watt, and performance that is up to 30 percent faster than the original GeForce GTX 480.
