I believe some of them had a disabled FPU but I defer to you on this if you say none of them did. The difference between a disabled FPU and no FPU isn't relevant to the point I was making.

Samples did have a disabled FPU but production material didn't, but to your point; I thought it was relevant because I thought you were making the point that the FPU was present yet unavailable to the customer. Apparently you weren't.

Tim it was even worse comparing a 386SX to a 386DX as the 386SX was still a 16 bit cpu whereas the 386DX was true 32 bit.

a 386SX performed like a 286. I was pissed about my 386SX when I got it as it was slow.

Processor Winstone Value
--------------------------------------------------
386/25MHz Winstone base w/4MB 10.20
386/25MHz Winstone base w/8MB 13.60
486/25MHz 26.32
CxS40 29.95*
486/33MHz 34.32
SLC2/50 36.70*
SLC2/66 37.80*
AMD40 40.30*
486DX2/50MHz 43.50
486/50MHz 47.94
486DX2/66MHz 50.68
Pentium 73.30
CX486DRx2/50 14.20 --
Rev to 486 2/50 15.40 Rev to 486 3/75 18.00

Keep in mind these could vary alot
486/Now! 11.20 / depending what system the upgrade
MCMaster 50PD/8 15.00 -- is going into (ie MCMaster was
only tested on a 386SX16 machine
and the rest a Compaq 386DX/25e
with only 4MB and with 8MB the
Rev to 486 2/50 did 23 Winstones
and the 486/33 did 36. So with
more memory and better peripherals
the upgrades should give truer 486
performance despite PC Magazines
slams against them in general.

Tim,

I seem to recall that the point with 486SX was that there was a socket for adding the co-processor, and when you bought the co-processor, it was a full fledged 486DX, and the original 486SX was disabled (but had to be in the socket).
