Thomson second-sourced for Cyrix, so it should be a relatively normally performing single clocked Cx486 (but on a 66MHz bus). I couldn't find the Cx486DX-33 in the Ultimate 486 Benchmark Comparison to compare speeds with, say, a 486DX2-66, but the DX2 comparison from Cyrix to Intel isn't a big gap. …

If it's like this: https://www.youtube.com/watch?v=OAhbsVbVLoI, it's probably single-clocked on a 66MHz bus. The description of the product says DX-66. edit: It definitely is. Same STPC chip which contains the CPU.
