Instruction timing as such is not relevant. Different implementations
had very different timings, not to mention that speed of memory also
makes a difference.
Devices basically do not have a strict timing either, but yes, there is
plenty of software that assumes that an interrupt does not

So how important is timing of instruction execution and device
