AMD K6-III (K6-3) processor families
K6-III (sometimes called K6-3) microprocessor family is based on AMD K6-2 family and improves it by adding an integrated on-die 256 KB level 2 (L2) cache. K6-2 microprocessors utilize L2 cache located on a motherboard - this cache runs at bus frequency, i.e. at 100 MHz at most. Integrated L2 cache on K6-III processors is much faster as it runs at processor frequency. As an added bonus, the L2 cache located on a motherboard works for K6-III CPUs as L3 cache. In general, integrated L2 cache on K6-3 processors greatly improves their performance - by up to 20% and more.
There are a few variations of K6-III microprocessors that target different segments of computer market:
All desktop and some mobile AMD K6-III processors are made on 0.25 micron technology. All embedded and mobile K6-III+ microprocessors are manufactured using 0.18 micron technology. The 0.18 micron processors have lower core voltage, run cooler than 0.25 micron CPUs, and usually overclock better.
