I will quote some figures from Byte magazine, July 1987 issue. I
personally do not doubt the Intel benchmarks at all. If they chose to
select benchmarks which show the best points of their product, can you
seriously believe that Motorola is so dumb that they don't do the same
thing?

The only comment I would make on this is that the 80287 was used rather
than the 80387. This typically would improve the f.p. performance by at
least 2:1. The 80387 has much faster trig functions (I have seen figures
indicating 10:1), which would improve the Savage benchmark performance.
