No, when Intel removed or disabled the onchip FPU.on their 486s. Calling those 486SXs.
Celerons are fine as well. They just had less cache than the "Pentiums".
That's kind of what I meant. That the SX specifically notes the removal of the FPU feature, like the Celeron which were usually gimped with part of the L1 cache. And as such, they were more affordable chips to purchase. Apologies for wording my thought poorly. What is interesting to me is that I remember hearing about the 486 back in the day and it having a built in FPU making it significantly more powerful than the 386DX it was replacing. And then later hearing about SX and DX variants. I was curious what was difference between the setting on my motherboard because it has 486, 486SX and then 487SX/486DX. And I was under the impression that there was no different between them, but I wasn't sure. I am trying to remember passing information from when I was 10 or 11 and so I cannot say how accurate my memory is. Thank you for the information.
-Edit- Sorry I can see how what I said didn't make sense. I know that the difference between the SX and the DX models are, the SX has no FPU and the DX does. But I was curious what the difference was, if any between a straight chip labeled 486, and the SX and DX variants. Seems from what I have been told is that the 486 and the DX chip from intel were the same, I think? I wonder if the guy on CPU galaxy has an intel CPU that is just labeled as 486 without a DX and SX delineation?
