Why intel make i9 with 8 cores, and not 10 cores like i9 10850k ? I already buy i9 10850k for 370 euros.

Intel made it with 8 cores because... 24 March 2021 23:46
To make this chip Intel designed it on a smaller nm then they back ported it to the current nm. This made it so it could only fit 8 cores.
