The first digit tells how many CPU's are capable of running in a single PC... so 1 is just a single CPU, 2 is dual, 4 is quad... I don't think anyone makes a motherboard capable of using 8 CPU's, but either way, the 8xx series supports it
The second two digits tell you the speed. So a 150, 250, 450, and 850 all run at the same speed.
