EDIT:
The first i486 was with floating point, and it was faster than 80386 from the get go.
Later when the cut down SX that didn’t have floating point was introduced, they called the non cut down version DX.
But the original i486 was similar to later DX versions and included floating point.
But admittedly the better prices for 486 was probably due to competition with AMD heating up.
