 For highly parallel floating point math workloads, the cards can speed up large computations by more than 10 times; Folding@Home, the earliest and one of the most visible users of the GPGPU, obtained 20-40 times the CPU performance.Each pixel and vertex shader, or unified shader in later models, can perform arbitrary floating-point calculations.Following the release of the Radeon R520 and GeForce G70 GPU cores with programmable shaders, the large floating-point throughput drew attention from academic and commercial groups, experimenting with using then for non-graphics work.
