Perhaps because I wait a year or at least a few months after a new CPU generation comes out I have not experienced the same problem with AMD CPUs. Instead, I have experienced the same problem with missing sensors many years ago when I bought the 1st gen i7 CPU. Meanwhile, the way Intel threw its users under the bus refusing to provide microcode for older CPUs when the CPU vulnerabilities were revealed and now news on Intel 13/14th Gen CPU degradation problems, convinced me to permanently turn my back on Intel. ;-) > Other example.

I must admit I have not come across this problem, perhaps because I do use edk2. > Other example. No XMP memory profiles. Will be a pain to actually OC > memory.

Depending on the MoBo capabilities you can tweak the memory clock manually if you really want to, or just switch on DOCP and it will achieve its overclocked performance level. Is DOCP missing on your MoBo? It may be worth checking if the latest EFI firmware is needed to make it available. > And finally another example. Not sure what the threadripper has.

I read there is a new AMD specific V-cache driver made available in the 6.13 kernel. Perhaps this will allow switching processes to the chiplet with the 3D cache? I wonder how much faster this will make compiling code ...

In my experience, new hardware takes a bit longer to bed in kernel-wise on Linux than on MSWindows. This is why I wait for a while before I jump in with my purchases. However, sometimes the jump in technology is so big and enticing it is hard to wait when your old system has been dragging its heels for years.
