some ppl said here that the 030 is twice faster per clock but it is not true
the 040 is 4 times faster than the 030 or the 020 at idem clock
ie sysinfo on a 030/25 reports 4.x mips the 040/25 reports 18.x mips
the 040 and the 060 are idem core and will work at idem speed per clock
ex a 040/50mhz is fast like a 060/50mhz
