OK OK OK! I dug out the literature..

Cyrix Fastmath (TM) 83D87 Processor

5.5 MFLOP System Performance
Reduced cycles/instruction		[compared to what? emulation?]
Most instructions accelerated by more than 5x
Lowest power consumption
Most accurate results - Transcendental functions accurate to more than
	65 bits - 1.5 x 2^-66
Fully 80387 compatible - verified with > 24,000,000 tests.
......
Achieves 4 to 15 times greater performance than Intel 80387 by implementing
its floating point primitive operations in hardware rather than in a 
microprogrammed sequencer. ....performs floating point at same speed as
80386 can perform integer additions.  ... instructions ..are binary and
function compatible with .. 80387.    ... clock rates of 25MHz and 33MHz.

The booklet lists a decent array of hardware and software products it has
been tested with. 

All the above is extracted without permission, and I accept no reponsibility
for any misrepresentation of this product. If you REALLY want to know, ask
them directly.
