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.
Let’s see what there is under the hood of this new video card: The GeForce GTX 275 is based on the same GPU than the GeForce GTX 295 (I didn’t say the GTX 275 has two GPUs: it’s a single GPU card: a half GTX 295). But today is also the day for NVIDIA to launch ATI’s Radeon HD 4890 competitor, the brand new GeForce GTX 275. Today, ATI has launched its new product, the Radeon HD 4890.
