Seemingly intimidated by AMD's new HD 4830, Nvidia has released a presentation claiming why its 9800 GT is, well, "better". Interesting that a 560 shader HD 4830 was referenced!
NVIDIA has issued a slide-show, a consolidated presentation taking into account, the findings of some review sources. In short, NVIDIA claims that the GeForce 9800 GT is not only faster than Radeon HD 4830, but also that its value-added features such as the CUDA HPC foundation and PhysX acceleration amount to a superior product all in all. Donanim Haber got their hands on this slide-show before anyone could, so here goes: GeForce 9800 GT vs. Radeon HD 4830 - a presentation by NVIDIA.
