There have been some major software updates to macOS and benchmarking software, so I thought I'd update the benchmark results. As before, my MacBook Air has the combined wind channel + heat sink + heat pad modifications, and I ran the tests in Intel Power Gadget 3.6.0, Geekbench 5.3.1, and Cinebench R23. I used the same set up as before, but also waited for the CPU to cool down to around 40℃ before running the next benchmark. Each benchmark was executed at least three times and I report the average.
When I run the stress tests in Intel Power Gadget, it seems that the max sustained frequency is 100MHz lower than before, but the CPU temperature plateaus at about 80ÂșC. I guess Big Sur is throttling the CPU even more?
