  1. Most of the common instructions actually finishes in one clock cycle these days, AMD and Intel have both worked really hard on that to reduce latency. But you're right, some instructions might take multiple clock cycles. On the other hand a core have multiple pipelines and can run multiple instructions simultaneously, filling pipelines with out of order execution, speculative execution and a second thread to ensure that execution resources are used even if one threads code doesn't use that resource in that moment.

  2. CPUs vs GPUs. Porsche vs a tractor or something like that... A CPU is fast, but a tractor can pull more. Or perhaps a semi? I don't know, something like that...
