The idea of open-source hardware is slowly slowly but surely gaining traction. VIA Technologies, Inc., joined in on the fun today by unveiling an open source reference platform for low power notebooks, based on its own processor technology (obviously). The CAD files have been released under a Creative Commons license. The machine is tentatively named OpenBook.

I'm afraid this is mostly nonsense - perhaps due to a badly written benchmark program (not uncommon). Actually, the Cyrix FPU needed 4-7 cycles to do a FADD (a typical operation) while the i387 needed 23-34, and the i287 took 70-100 cycles to do the same.
Regarding FSQRT (important in many early 3D games) the numbers are 59-60 for Cyrix, 122-129 for the i387, and 180-186 for the i287.
On integer code, the Cyrix chip was faster than a Pentium, "clock for clock", and thus much faster than a i486 (see datasheets).
Also, while VIA sold the Cyrix designs for a while, the IDT/Centaur-designed C3 and C7 has nothing to do with the Cyrix chips, at least not regaring technical solutions used.
