How powerful is the i9-12900H ?


hey forum.
I'm thinking of buying one of these mini PC's that come fully loaded with the good specs. I want an i9 just because it would be an upgrade from my current i7 laptop of many years, so, curious to see how much more powerful it feels.

I've read a processor which name ends in 'H' isn't as powerful as those ending in 'K', but I've got a really good price here for an i9-12900H (14 cores, 20 threads). Would you add an extra 200 bucks or so if it meant getting one of the better i9 models in the PC ?
I don't do gaming, I produce music and do video editing.

Any thoughts would be interesting to read ! thanks.
