And why is Pentium 4 80786 while Pentium M and Athlon 64 are 80686? | | - Exophase | There is no such thing like 80786! The last was 80486, and becouse of legal issues Intel changed its "labels" to PENTIUM class (I remember NEXTGEN was involved). My ways of thinking (CAN BE NOT TRUE): 80586 class = Intel Pentium, or 100% compatibile 80686 class = Intel Pentium MMX, or 100% compatibile 80786 class = AA-64 (or AMD64) and EM64T CPU's, or 100% compatibile (hope to be, for now ONLY MY ASSUMPTION) this way Intel Pentium II,Intel Pentium III,Intel Pentium 4, AMD K6-2,AMD K6-3,AMD Athlons (in all mutations), some other, not mentioned CPU's, are just 80686 CPUs, with some additional instrucions. post a followup message (Be nice... or be blocked.
