But even then it was unfair to the Compaq seeing as they were using the "old" model which used this older FPU. Also Mac had cacheing where new Deskpro's has integrated. If this was a fair comparison should have had the 80387 in the new deskpro (6 times faster than 80287) and configured compaq with equal cache. Code on the Mac was compiled using a 68020 C compiler. So the Compaq was actually at a disadvantage seeing as it was not able to use their nice new 32 bit FPU where the Mac was and the Mac could speed up some of the disk action with it's cache and the Compaq was unable because they use older daekpro. I would say that if this would done you would even be more disapointed in the resaults. Must remember that Mac's have a definate disadvantage when it comes to many benchmarks, putting the CPU asside most systems offload the processes conserning gaining data from the disk, Mac's do not. Saving grace on a Mac II is you have slots and can add a card to do this off load processing. What it comes down to is Intel has FINALLY made a good chip, it DOES outperform the 68020 at equal clock speed. I am more interested in the next generation the 486 vs the 030, that should be very interesting. -- Steven Goodman Lake Systems Milwaukee, Wisconsin UUCP: {ihnp4,uwvax}!uwmcsd1!lakesys!steven
