Either your math is off, or they've changed it. $ lscpu | egrep '(Vendor|MHz|MIPS)' # This PC Vendor ID: GenuineIntel CPU MHz: 1599.975 CPU max MHz: 3800.0000 CPU min MHz: 1600.0000 BogoMIPS: 6800.59 $ lscpu | egrep '(Vendor|MHz|MIPS)' # Certain VPS Vendor ID: GenuineIntel CPU MHz: 2099.996 BogoMIPS: 4199.99 And, $ lscpu | egrep '(Vendor|MHz|MIPS)' # Xeon X5675 Vendor ID: GenuineIntel CPU MHz: 1600.000 BogoMIPS: 6117.70 > How can you measure and compare processor performance from the mere clock frequency ? That's I agree with. REco
