iComp: A CPU benchmark devised by Intel. It tests CPU capability only and is reported to be heavily weighted toward Floating Point operations. (By a remarkable coincidence, Intel is noted for its highly optimized integral FPU Units.) The Intel 486SX25 has an iComp of 100. The Wintune Benchmark program reports iComp and appears to be the only generally available tool for measuring iComp values. Intel replaced iComp with iComp2 and later with iComp3. The iComp rating is marked on Intel CPUs. Some published iComp Values are:

Intel seems to have stopped publishing icomp ratings in 1998 and restarted with an unrelated iComp3 in 1999
