K6-III

K6-III+ (K6-III Plus) was a family of mobile microprocessors introduced by AMD in early 2000 as a replacement for the previous generation of K6-III mobile processors. K6-III+ enjoyed higher performance and lower voltage as a result of a die shrink.

Overview

Introduced in April of 2000 and on AMD's new 0.18 µm process, the K6-III+ was designed to replace the older K6-III-P mobile processors. Due to the processor shrink, the new models operated at higher frequency, dissipated less power, and operated at lower voltages. Many models could be clocked as high as 600-650 MHz. K6-III+ never recived as much attention because AMD was focused on promoting their Athlon and Duron (K7) families instead.

Architecture

Main article: K6-III Microarchitecture

K6-III+ models are architecturally identical to the original K6-III, except manufactured on a 0.18 µm after a process shrink. K6-III+ models do incorporate PowerNow! as well. Instructions set: MMX , 3DNow! , Extended 3DNow! (Extended MMX NOT support)

K6-III+ Embedded models

Note that while AMD's Ordering Part Number (OPN) included the "E" for embedded, the actual chips themselves did not. This makes it impossible to distinguish some K6-III+ Embedded parts from K6-III+ Mobile by just looking at the chip markings.
