Good Grief! And I thought I was always the last to know! Chris is right.
But the change occurred around 1997 (8?) or so? About 10 yrs ago? It was
because the average consumer only knows MHz as the performance indicator
and is not aware of pipelines, on-board cache, instruction sets,
multiple decode, predictive ...

So AMD needed a way that could immediately clue the clueless that this
was "approximately equal to Intel at xxx MHz". It worked ... sorta. They
took a lot of heat about it from the old-guard tech types. But they
managed to avoid bankruptcy and are still bringing superior products to
market.
