Under OS/2 on an IBM 686-133mhz it runs a bit slower then an Intel 120mhz
Pentium due to the code being optimized for the Intel chips. Normally the
Cyrix/IBM 686-133mhz will outrun an Intel 166mhz Pentium in integer
operations.
The deschal4 (486) and deschal5 (Pentium) run at the same speed on this
chip,
the deschal6 (pentium Pro) is a bit slower.
