The bitness of the processor and its clock frequency?

Question

Iron

Hello everyone, I have a question about processors, or rather about this slide.

That's the question: does the processor capacity depend on the clock frequency?
That is, I mean that the bit depth of a certain processor is involved - constant, either 32 or 64 bits, but the higher the clock frequency, the faster the processor runs - that is, the bit depth displays a kind of clock frequency, as if "attached" to it - t .e I wanted to ask if, for example, a 32-bit processor can work with the same frequency as a 64-bit one? Did I understand correctly?

Answer 1

Consider that in one cycle the processor executes one instruction, for example, addition of registers. Registers have a "size" - word length. The most important difference of a 64-bit processor is the ability to operate on 64-bit memory addresses. The addition of long registers (64 and 128 bits) was also on 32-bit processors with the MMX extension. But they could not access physical memory at addresses larger than 32 bits (4GB)
