I haven’t had time to read through the entire thread yet, but I wanted to add my benchmark scores & temps from my bone stock Framework 16 with Ryzen 9 7940HS under Windows 11 Pro just for reference. It looks like I have a fairly large gradient in temperatures across my cores with one of them hitting 100C at full load but the CPU power draw stays above 39 watts, so I don’t suspect I’m thermally throttling too much if any. I hope my information below serves as another data point for this thread and I look forward to reading the whole thread when I have more time and it’s not Thankgiving! 
BTW, Happy Thanksgiving! 
Cinebench R23:
Multicore: 13391
CPU-Z Benchmark v17.01.54
Multicore: 6351.1
Singlecore: 681.7
CPU-Z Benchmark v19.01.64 AVX-512 (Beta)
Multicore: 7090.4
Singlecore: 881.7
When I run a “stress test (v17.01.54)” under CPU-Z Benchmark multicore it will drop down slowly starting at around ~6600 dropping down rapidly to ~6300 and then more slowly dropping over several minutes until it finally levels off at exactly 6175.1 and it will stay there for however long I run the benchmark in a room with ambient temp of 73F. Every core stays between 4.166ghz & 4.215ghz throughout the stress test.
Max reported power & temps via HWMonitor once stress test (v17.01.54) stabilized
Core 0 : 79.8C
Core 1 : 88.6C
Core 2 : 91.3C
Core 3 : 98.4C
Core 4 : 96.0C
Core 5 : 100.1C (Drops to 100C and stays there for entire stress test)
Core 6 : 93.9C
Core 7 : 98.5C
Package: ~39.2W
Framework 16 Max Temps reported by HWMonitor during stress test (v17.01.54)
