The Nvidia card, however, has proven to be slightly faster in games, so the GTX 280M can therefore be rated more highly in terms of real-life performance. Compared to the performance of the Mobility Radeon HD 4870, the GTX 280M is about equal in synthetic benchmarks, if not slightly lower.

The stream processors handle all of the workload that would have otherwise been processed by pixel or vertex shaders. VRAM can be up to 1024 MB GDDR3 clocked at either 800MHz (on MXM2 boards) or 950MHz (on MXM3 boards).ĭue to the full 128 shader cores, the GTX 280M is about 10-25% faster than the older 9800M GTX and slightly faster than the 260M. Dedicated pixel and vertex shaders of yesteryear are gone in favor of 128 stream processors running at 1250MHz on the GTX 280M. Switch times on the graphics card now completes in just a fraction of a second, compared to a full 7 seconds on the 9800M GTX,Īs with all DirectX 10 graphics cards, the GeForce GTX 280M renders 3D images using " Unified Shaders". Hybrid Power makes an appearance on the GTX 280M as well, but with much improved performance. The chip is produced in 55nm with all 128 pipelines enabled, as opposed to the GT 9800M with only 112 pipelines produced in a 65nm process. Therefore, it is actually more related to the GeForce 9800 GTX+, both performance-wise and architecturally, than to the GTX 280. The NVidia GeForce GTX 280M is a high-end graphics card as part of the 200M series and is based on the G92b core (Desktop GeForce 9800 GTX+).
