Intel pushed the 486 up to 100 MHz via the iDX4 chip (which lost the i486 branding, but it's still what it is). Initially intended for embedded systems, it was sold directly also to consumers with the "OverDrive" brand attached. (Maybe it was unsold stock from the embedded attempt?)
AMD would further push its own 486 chips to 150 MHz, and I recall the raw clockspeed allowed it to stay competitive against the lower-end Pentiums (60-75 MHz), but architectural changes in the Pentium (branch prediction and out of order execution) really let the Pentium fly away from the 486 at fewer necessary cycles.

They also spent some effort marketing the DX4 as a low end alternative to the Pentium. It was possible to buy/build DX4 machines. Trouble there is the same as any other low end offering of the time - it got steamrolled by better technology coming down in price as quickly as it did. The window of opportunity for anything low end was not that large.
