One is a Cyrix 'p150+' and the other is an Intel 150mhz pentium. The only difference is the Cyrix floating math is NOT comparable to a pentium. I have a program mclock (get it at: ftp://cold.org/brandon/mclock.c.gz, compile with gcc -O). It basically does a few math functions several thousand times, clocking each cycle. It returns the following results: Cyrix 6x86 p150+ (120mhz): Float Multiply: 1.2383 seconds. Float Divide: 1.8352 seconds. Fixed Multiply: 0.2938 seconds. Fixed Divide: 0.4039 seconds. Intel Pentium 150mhz: Float Multiply: 0.3328 seconds. Float Divide: 0.8398 seconds. Fixed Multiply: 0.2555 seconds. Fixed Divide: 0.8414 seconds. -Brandon Gillespie
