【正文】 1999 Feb 22 AMD release K6III 400MHz version, 450 to OEMS. In some tests it outperforms soontobe released Intel PIII. It contains approximately 23 million transistors, and is based on 100Mhz super socket 7 motherboards, an improvement on the 66MHz buses their previous chips were based on. This helps its performance when pared to Intel’s Pentium II which also uses a 100MHz bus speed. 1999 Nov AMD release Athlon 750MHz version. 29 20xx Jan 19 Transmeta launch their new ’Crusoe’ chips. Designed for laptops these prvoide parible performance to the midrange Pentium II chips, but consume a tiny fraction of the power. They are a new and exciting petitor to Intel in the x86 market. 20xx March 6 AMD Release the Athlon 1GHz. 20xx March 8 Intel release very limited supplies of the 1GHz Pentium III chip.

This list is not intended to be an exhaustive pilation of microprocessors, but rather a description of designs that are either unique (such as the RCA 1802, Acorn ARM, or INMOS Transputer), or representative designs typical of the period (such as the 6502 or 8080, 68000, and R20xx). Not necessarily the first of their kind, or the best. A microprocessor generally means a CPU on a single silicon chip, but exceptions have been made (and are documented) when the CPU includes particularly interesting design ideas, and is generally the result of the microprocessor design philosophy. However, towards the more modern designs, design from other fields overlap, and this criterion bees rather fuzzy. In addition, parts that used to be separate (FPU, MMU) are now usually considered part of the CPU design. Another note on terminology because of the muddling of the term RISC by marketroids, I’ve avoided using those terms here to refer to architectures. And anyway, there are in fact four architecture families, not two. So I use memorydata and loadstore to refer to CISC and RISC architectures. This file is not intended as a reference work, though all attempts (well, many attempts) have been made to ensure its accuracy. It includes material from text books, magazine articles and papers, authoritative descriptions and half remembered folklore from obscure sources (and who I’d like to thank for their many helpful ments). As such, it has no bibliography or list of references. In other words, For entertainment use only. Enjoy, criticize, distribute and quote from this list freely. By: John Bayko (Tau).
