In regards CPU's inter-compatibility on most PC's Intel South Bridge Chip H81 or in my case, my OptiPlex 3020 (i5-4570 @ 3.20GHz (3.60GHz) 22nm Haswell 84W 6MB Intel HD 4600)
....being the same socket (LGA1150 as one of my of the PC's Lenovo ThinkCentre M73 SFF
MoBo LENOVO 3098 (SOCKET 0) South_Br Intel H81
i7-4790S @ 3.20GHz (4.0GHz) Q2'14-'7_2021
Socket FCLGA 1150 22nm Haswell 65W 8MB
iGPU Intel HD4600 2GB Max.Res D/P 3840x2160 @60Hz
(I also own 3010 SFF and 5050 SFF but they are different socket computers...))
