Phoronix: NVIDIA GeForce GTX 280M
After launching the GeForce 200 series last year, NVIDIA unveiled the GeForce GTX 260M and 280M GPUs for notebook computers earlier this year. The GeForce GTX 280M is currently NVIDIA's fastest notebook GPU, even though it is derived from the GeForce 9800GTX+ core rather than the GTX 280 desktop variant. This 55nm notebook GPU has 128 processing cores, supports two-way SLI, features NVIDIA PureVideo HD technology (important for VDPAU usage under Linux), and other features to pack a desktop performance punch in notebook computers. The Linux-friendly System76 manufacturer recently introduced the Bonobo Professional notebook computer with the NVIDIA GeForce GTX 280M and an Intel Core 2 Quad processor, which we happen to be looking at now and today are delivering some initial performance results from this high-end NVIDIA GPU under Ubuntu Linux.
