It turns out that the 486SX2 and 486DX2 CPUs I've been using are actually the "S" versions, meaning that they are "SL Enhanced."

Does this mean only that they are power-saving CPUs that can run at 3.3v as well as 5v?

Just wondering if there's any performance-related difference between these and the "non-S" versions.

They cannot run at 3.3V.Compared to regular models they just support a set of power management technologies.

Notable feature is the SMM (System Management Mode) which although designed for power management purposes can be used for some non-PM purposes too.
