Would it not be possible to fake most of those by spoofing the model the CPU reports, like what happens with GPUs?
Yeah, I think this is the real danger. "I don't know why this i9 isn't performing like expected" is a problem where the cause may be much harder to trace if people can reliably change what the processor reports itself as. And even then, the question only even gets asked by those who actually benchmark it.
With GPUs you can do things like dump its BIOS, alter the identification string, and then re-flash the card.
I've modified a lot of GPU BIOSes to tweak GPU and memory clock timings or enable Mac support.
CPUs aren't that easy to modify. I am not aware of any consumer tools that can simply re-write CPU's internal code.
Regardless, the first time you run a benchmark and it shows that your CPU is really X and not Y, you will know something is wrong.
