It has been rumored that NVIDIA’s upcoming graphics cards based on Fermi architecture will outperform ATI’s top of the line graphics cards. And a video posted by NVIDIA lends some creditability to those rumors. In the video, synthetic test of Uniengine shows  that maximum frame rate of both GTX 480 and HD 5870 are almost same. However, GTX 480 offers much faster performance under high stress in DirectX 11 games. The NVIDIA card produced 40 frames per second under high stress, whereas ATI Radeon HD 5870 was only able to offer choppy 20 fps. According to Electronista, GTX 480 will be faster for games offering DirectX 11 features like tessellation to dynamically add details. Also, GTX 480 will have better support for general computing than ATI Radeon HD 5000 series, as Fermi architecture is designed to offer native hardware support for OpenCL and CUDA.
