Well, what did you expect ? :)

---------------------------------------------------
iDX2/66		1.00	(6:40 => 1.00)	(se)
aDX4/100	1.26	(5:15)
iDX4/100	1.36	(4:50 => 1.38)	(roberto)

a5x86/133-WB	1.63	(4:00 => 1.67)	(ec0)

(ec0=Eric Chet, roberto=Ollivier Robert, se=Stefan Esser)

The "c't 3/96" column lists some (of 18) results for
i486 compatible CPUs. The Cyrix 5x86 results depend 
too much on the motherboard and chip revision to be
useful as a system performance indicator (the 100MHz
version seems to lie in the middle between iDX4/100
and AMD 5x86/133 at about 1.45 to 1.49).

The c't numbers were obtained using the Babco test
suite based on Windows programs. But since it nearly
perfectly matches make world times, I think those 
values can be trusted anyway ... :)

I've just found an offer for a Dirty Tag RAM at 
13.50DM (about $8.00 taking local VAT into account)
and think this is a good price for speeding up the
make world by another 20 minutes ...

BTW: The P75 with ppipelined burst cache is about
as fast as a P90 with Neptun, SiS or Triton with 
asynch. cache SRAMS. Seems the AMD 5x86 really is
a good buy at $80 (135,00DM).
