The 80486SX was introduced two years after the 80486 and did not have an FPU (unless it was purchased as an option).
I think the meaning of my comment was clear: the 80486 was the first Intel CPU guaranteed to have an FPU. I didn't say all the Intel CPUs which came afterward were guaranteed to have them...
- postmodest 3y agoMy first "my own purchase" PC was a 486sx. So as a _line_, "the 486" wasn't guaranteed to have an FPU.
- justin66 3y agoI guess that's true. I never really thought of them as the same thing. Looking over some old info about the "i486" (I swear I had completely forgotten about the i) was a treat. It's only barely believable but I think the sheer annoyingness of Intel's marketing and market segmentation might have actually peaked three decades ago.
