Intel have a different marking system for their CPUs. Have a look at the top of this Pentium II processor first.
As you see, Intel's system is easier to understand for a layman. Most important for you is the top line of this marking.
This figure says it all: Internal clock speed, size of L2 cache, frequency of the Front Side Bus and the core voltage of a Pentium II processor.
Comparing a Pentium III to a Pentium II, you can recognize that there is no big difference in the marking at all. The top line with the most important pieces of information is still the same, only the additional manufacturing markings differs slightly.
- Slot A - Card Module - Athlon
- Socket 370 - PPGA, FC-PGA, Celeron, Cyrix III And Pentium III
- Socket 7 - CPGA, PPGA - Pentium, Pentium mmX, K5 And K6 Series
