What types of Pentium III are Coppermine?

Difficult question, bearing in mind the numerous variants that Intel has extracted to the market. At present there exist or are foreseen not less than 16 models different from Pentium III (!) for teams of dessert:

(*) Foreseen, but still not available in format Slot1.

The previous picture, apart from demonstrating my awful taste concerning colors - almost bordering on the color blindness - needs the following explanation on the nomenclature used by Intel:

• Pentium III "E": based on the nucleus Coppermine (256 KB of integrated cache memory);
• Pentium III "B": based on the ancient nucleus, with bus of 133 Mhz;
• Pentium III "EB": based on the nucleus Coppermine (256 KB of integrated cache memory) and also with 133 MHz bus.

Also, Pentium III without letters o with letters between parentheses are:

• 450, 500, 550 and 600 MHz models: original Pentium III (ancient nucleus, 100 MHz bus);
• 650 MHz models or more: of the type E or EB, although officially they have not said letters since they cannot make a mistake with any other.

Simple, no? (Well, perhaps not). in any case, the "Authentic Coppermine" would be the models EB, or in any case the EB and also the E; the B are ancient Pentium III but with a more rapid bus, a progress that, isolated, scarcely fond of the yield.

On the other hand, three models of Pentium III have presented before themselves for portable, to 400, 450 and 500 MHz, that although they do not continue the explained nomenclature above we might consider to be Coppermines "E", since they have 256 KB of cache memory L2 integrated but they use a 100 MHz bus. And of course, his connectors are completely different, more compact, for being destined for portable teams.
