> Most modern computer cores can operate at a sustained rate of 3 billion instructions per second, with much faster peak speeds. 3 billion instructions per second is an IPC less than 1. You can often expect IPCs closer to 2 even on older Skylake derived cores, so just shy of 10 billion instructions per second. Very modern top end cores do even better.
