This is interesting.  There has been damaging comparisons made between a Palm
running at 50MHz and the phantom Star Sapphire running at 16MHz.  If the 16MHz
RISC chip is optimized, then WRT strength could it be said to be running faster?

Now I know that comparing the Palm CPU and a RISC chip is like apples and
oranges, or apples and coffee cups, but if a very rough estimate could be made
could you answer this question:

What is the estimated MHz speed WRT a Palm of a 16MHz RISC processor?
