What about i9 9900K? Is it recognized properly now?
 
It will recognize the i9-9900K only if you add this:

If I don't spoof the CPU type as you mentioned above, the 9900k is recognized as "3.6GHz Intel core i7" (8 cores, 256KB/core = 2MB L2 cache, 16MB L3* cache) in 10.14.5 (was "unknown" in 10.14.4).
So I guess it's now ~~recognized~~ as an i7-9700K, right?

However (and in addition to the L3 cache value mentioned), Activity Monitor still reports 16 threads* (this is right for the 9900K) rather than only 8 (as expected for the 9700K).
So I guess it nevertheless ~~works~~ as an i9-9900K, right?

Now if I spoof the CPU type in Clover, would It change anything performance-wise? Or would it only be cosmetic?

* these values all correspond to the 9900K and not the 9700K

Correct. ‘About this mac’ is purely cosmetic and all 16 threads of the i9 should be available for use.
 
side note: I'm still using iMac18,3 (since 19,1 was not available back then).
Will I see any improvement if I switch to 19,1 or will it be the same?

Have you tried this yet?
 
Not yet.
AFAIU this will not change anything. Am I wrong? Let me know please...

Haven't tried it either. I added 0x1005 to identify. I will update the machine later as I need to change some other things too.
 
OK :)
Please let me know if you notice any improvements.
