The statistics unveil more than 40 percent of Folding@Home's computing power now comes from NVIDIA's CUDA-enabled graphics cards. Just 11,370 systems with NVIDIA cards deliver 1,251 teraFLOPS of computing power, significantly more than the 198 teraFLOPS provided by 208,268 Windows PCs.
If you do the math you'll see that an average NVIDIA or ATI graphics card running Folding@Home delivers 115x more computing power than the average system with Intel or AMD processors. Furthermore, the GPUs are also considerably more powerful than the PlayStation 3's Cell processor.
