Well, I think the numbers are pretty fair, assuming that the bogomips number reflect a certain amount of external memory accesses at 66 MHz external bus clock. > > Any experience? Thanks Yes, we have a 8250' powered custom board running at: - cpu_clk 196608000, cpm_clk 163840000, bus_clk 65536000 Our ported good old PPCBoot 1.1.5 reports: CPU: MPC8260 (Rev 14, Mask unknown [immr=0x0062,k=0x002d]) at 196.608 MHz And the 2.4.21 kernel: Calibrating delay loop... 130.66 BogoMIPS HTH, -Scop. > > Jaap-Jan > > --- > J.G.J.
