Finnish startup says it can speed up any CPU by up to 100x using a tiny piece of hardware with no recoding

Others have already laughed at this idea, but on a similar topic:

I know we’ve basically disabled a lot of features that sped up the CPU but introduced security flaws. Is there a way to turn those features back on for an airgapped computer intentionally?

Haven't used it in years, but it might still work:

The kernel option is mitigations=off, if you want to try adding it to your Grub command line? From the testing I've done, provides no benefits whatsoever - no more frames in games, compilation runs no quicker, battery life on a laptop is no better.

Haha okay

Edit: after a skim and a quick Google, this basically looks like a packaging up of existing modern processor features (sorta AVX/SVE with a load of speculative execution thrown on top)
