5k iMac 2015 late cpu replacement test
I have an imac 27" 2015 late model. I'm going to experiment with upgrading to Kaby lake 7700k cpu. I will share the results soon. Good luck to me.
I gave it a try! I installed 7700k CPU in my iMac today. It did not recognize it.
I lost money and time, as I was curious if it would work. Sadly no soap.
While these chips are very similar (review the specs sheets below) I don't think it will work as the systems EFI likely won't recognize the chips Device ID code.
If it does work you'll need to run some benchmarks to see if you gained any real performance.
