I just notice that the i7 is substantially faster than the i5 in Geekbench 5’s CPU benchmark, but Geekbench 5’s Compute benchmark (which only tests the GPU) actually comes with a lower score. I found out the reason - the i7 CPU becomes much hotter than the i5, and the i7’s heat negatively affects the Compute benchmark score. When I force the Fans to full blow using Mac Fan Control, the Compute benchmark of the i7 actually is higher than on the i5. Anyone see these same problems, with the i7 getting hotter than the i5?
I love this clear procedure, thanks for Andrew and the other contributors for providing it! Never thought I’d be able to replace the i5 logic board in my MacBook with a new i7 one, but just did it. I got the new one with the heat sink attached, but decided to remove it and follow the procedure as described, all steps. I put a little Arctic MX-4 compound, only on the CPU (not the GPU) and the i7 works flawlessly. I already replaced the paste on another i5 that had overheating problems before (also thanks to iFixit) so I knew well how to do that.

You can order a new bottom plate with the new serial nummer custom printed. Several suppliers in China provide that service.
