Indeed I didn't remember it correctly:

According to https://tfhe.github.io/tfhe/ states:

> Each binary gate takes about 13 milliseconds single-core time to evaluate, which improves [DM15] by a factor 53, and the mux gate takes about 26 CPU-ms

Addition of two bits can be implemented using 5 binary gates (fulladder) Hence to add 2 32 bit numbers ~416ms => 2 additions per second

EDIT: Shame I cannot edit my original post

This would mean that ~2500 CPUs could do 5000 operations per second, which is amusingly close to the same compute-per-square-foot as the ENIAC.
