How can I get CPU cache performance data?

Question

assembler

Hello! Processor manufacturers provide data on the sizes of registers and cache memory 3 levels. But I did not find data on the access time in cycles. It would be possible to write tests, but I would like to receive data from manufacturers. Help, who knows.

Answer 1

It all worked and was predicted somewhere up to 386 processors. On more modern machines with a superscalar architecture and a software-controlled instruction translator, this translates into a large number of options, it literally depends on the version of the microcode (which is loaded into the CPU dynamically )

Answer 2

Guess the author on the issue, instead of describing the problem that needs to be solved, he tries to solve it with his outdated knowledge by 20-30 years.
