G80 GPU Notes
| Each Streaming Multiprocessor(SM) in the chip architecture contains 8 SPs and 2 SFUs. Each SP can fulfill up to two single precision operations MAD per clock. Each SFU can fulfill up to four operations SF per clock (these units can also handle single-precision floating-point multiplications per clock). The approximate ratio of operations MAD to operations SF is equal 2:1. The theoretical SP + SFU performance in single-precision floating point operations [FLOPSsp + sfu, GFLOPS] of the graphics card with shader count [n] and shader frequency [f, GHz], is estimated by the following formula: FLOPSsp+sfu; f × n × 3. Alternative formula: FLOPSsp+sfu; f × m × ( 8 SPs * 2 (MAD) + 4 * 2 SFUs ). [m] - SM count. SP - Shader Processor (Unified Shader, CUDA Core) SFU - Special Function Unit SM - Streaming Multiprocessor MAD - ADD+MUL |
