I am looking for a CPU testing software. So, which would test every possible function of the CPU, many times and in many configurations, and displays its results.
In ideal case, it would be similar in its inner workings to memtest86+, which does with RAM what I am seeking for CPU:
- minimalistic GUI
- boot-time functionality for OS-less hw control (i.e. it's independent from whatever OS is installed on the computer, as it includes its own minimalist OS)
- low-level asm or near-asm implementation
But note, these items are only advantages and not strict requirements.
