Interesting!
There are different verions of the K6-III CPU though,
for instance core-voltage may differ.
The lower the core-voltage the less heat dissipated for a CPU rated at
the same speed.
The K6-III processors are difficult to obtain, we are looking for them as
it appears that the increase of instruction cache size from 64KB (K6-2) to
128KB (K6-III) does impact performace.
