Now the desktop is another issue. It's on Win 7, i7 6-core at 3.33GHz with 24GB of RAM and about 9TB of disk space. MIPS isn't the only measure of power. People wondered why VisiCalc was faster on an Apple II (where it was developed) than on the first IBM PC. Think about it. A 1MHz 6502 has a minimum instruction time of 2 cycles and a maximum of 14 (averaging around 6 in reality). The 8088/8086 chips at 4.77MHz had a MINIMUM of 14 cycles and a maximum of 156 with an average of about 86. Literally apples to oranges.
