Performance Hit on Kaby Lake with Windows 11?

[NegativeROG]

I've heard that if Microsoft OK's a workaround and allows Win11 to be installed on 7th Gen Intel, there will be a performance hit.  Do we have any idea how MUCH of a performance degradation?  So far, my expensive OC'd water-cooled i7-7700k is waiting for me to stick the TPM in the MOBO and download the update.  But I want to know what I'm losing, as opposed to waiting until 2025 and just building a new PC (the system I'm referring to is a spare, only used on occasion for 1080 gaming).  Am I gonna lose 1-2%?  I'll do it now.  Am I gonna lose 35% of my performance?  I'll wait until Win10 reaches EOL, and go with a Ryzen 9 8900x.  Thanks for any input.

You don’t need a tpm, there’s a firmware on in the bios options.

you can install it now with workarounds and you have the same performance if not better than windows 10

I tried it with a late 2016 Pentium CPU (I know, not amazing). I definitely noticed a performance drop, after doing benchmarks it was about 10-20% I believe. For a 7700K the difference would probably be smaller but still noticable.
