I have an iMac 2010 21.5 screen with an i3-540 processor, 12GB ram memory, Ati Radeon HD4670 and macOS High Sierra. I upgraded my CPU to i5-660 3.33Ghz, same TDP, socket, etc. My iMac started fine but everything worked slower, I cannot watch youtube without dropping frames, the same on ZOOM. I run Geekbench 5 and here are the results i3-540 Single core 511, Multi core 1122 i5-660 Single core 226, Multi core 519 What did I do wrong?
