AMDK6 and P-II
On Mon, May 31, 1999 at 11:31:37AM +0530, Thus spoke Rajiv Dhinakaran :
--> The AMD K6 is an excellent processor for Linux, and gives P-II class
--> performance at least in linux.
As for compatibility, AMD K6-2 is a pin-for-pin replacement
to Pentium chips on socket 7, ( mother boards should have
split voltage capability to use AMD K6). AMD K6-2 goes in to a socket 7
and almost gives the performance of a P-II of the same clock
speed. Except if you are only doing floating point operations,
P-II is about 30 % better.
here are some benchmarks
