even pushed it to 120MHz with 0.35 micron. I never understood why these were actually called DX4 as the clock multiplier was 3!

I had a DX4 120 with 16mb RAM. It was a great machine at the time. Loaded Need For Speed faster than a P75.

Marketing is my guess. Four is bigger than three. Was also the times of "PR" scores.
People are thick. Which is also why ¼-pound burgers outsell ⅓-pound ones.

I read that DX3 was an internal Intel designation for a 2.5x clocked 486, which was developed past the prototype versions, but never shipped in volume.
Hence when a 3x clocked 486 was developed it needed to be DX4.

My recollection is that if the part numbers were technically descriptive - AMD could copy and use the Intel part numbers on their own chips. By making them "random" - AMD couldn't copy them.

I used to have a cyrix 486dx4-100 at that time. It was performing well and could be a little bit overclocked.

I believe it's due they having four times the performance of the original DX 25Mhz one from launch... 1x25Mhz vs 3x 33Mhz (99.9Mhz)
