I'm a bit curious why this couldn't have been covered earlier by simply having the OS disable some cores on a 4-module 8-thread part. After all the video does point out that if only one thread uses one module, it as full access to all the resources of the module.

Also, the benchmark is clock-for-clock, so while the older Phenom II looks like it's ahead, the Buldozer should be able to go faster still.

All that said, I really enjoyed this retrospective look.

There were some benchmarks at the time with disabled cores, for example: https://www.hardware.fr/articles/842-9/efficacite-cmt.html
