9 lut 2018 · Is there a good benchmark database where I could possibly compare the integer performance of these classes of processors? I'm particularly curious about how a fast 286 (Say a 286-20) compares to a slow 386 (Say a 386SX-20), and how far apart 386SX40 vs 386DX25 vs 386DX40 stand from each other..
