The IBM/Cyrix 6x86MX Processor
|
|
The IBM 6x86MX is in fact an IBM manufactured and labelled Cyrix 6x86MX. The successor to the 6x86 and 6x86L is the 6x86MX (M2), intended to compete with AMD's K6 and Intel's Pentium MMX. The 6x86MX is an evolutionary step from the 6x86 and is very similar to it in internal function.
The 6x86MX supports the MMX extension and also features several other improvements over the original 6x86 chip. The internal cache was increased from 16 to 64 KB, a 256 byte additional pre-cache was added to help improve efficiency in how the regular level 1 cache is operated, the Branch Prediction was improved and the internals of the chip have been optimized for 32-bit operation.
