  1.  @abdullahpatel2120  That is not true. Things like multiply and divide are single instructions, which often take multiple cycles. Processor references list the amount of cycles such instructions take. What you're refering to is latency, which means additional cycles before the result becomes available. During that latency a processor can execute other instructions (provided they are not dependent on the result), but certain instructions (division in particular) do take multiple cycles before the ALU will do anything else.

  3.  @abdullahpatel2120  No. Hz just means the number of clock cycles per second as the original comment said.

  4. And FPU. Floating P....oint Unit. 🤔 Damnit.

  5.  @doigt6590  They are, but not named as such.

  6. ​ @warlockpaladin2261  The only real measurement is benchmarking though, as performance depends a lot on what exactly is supposed to be done. Flops measures floating point operations, which for a lot of software is almost or completely irrelevant. As for "practical" speed, what the average consumer is going to notice most nowadays, is not the speed of the CPU, but the speed of IO, and the quality (or lack thereof) of software running on the computer. If you manage to install only software from the 80's/90's on a modern desktop, it will feel as though everything responds instantaneously. Unfortunately, nowadays a lot of programmers seem to think resources are practically limitless (which is kind of true until you consider there may be 50 processes running that are written with the same mindset). Modern desktops are basically like using a space shuttle to go to the grocery store. It's impressive, sure, but it's a bit of waste to take 1GB of memory on a 16-core supercomputer to display funny pictures of cats.
