Unfortunately, I wasn't able to catch either COMPCON, or Dave's later
CRISP talk at Stanford, but I do believe that was X a 750, not a 780
[BTL-Research usually compares that way since they have 750s!]. From
reports of the Stanford talk, I also heard (maybe somebody else can confirm):
13X (750) Dhrystone (11,000? hard to know what their 750s do?)
20X wc
30X Ackerman's function
