I said triple, because the competitors are expected to have a double speed in a few months.
If M4 were 3 times faster than it is, it would have remained faster than Strix Point and Arrow Lake, which would have been replaced only next year, giving supremacy to M4 for more than a year.
If M4 were twice faster, it would have continued to share the first position for more than a year. As it is, it will be the fastest for one quarter, after which it will have only half of the top speed.
And then Apple will release M5 next year, presumably with another increase in TOPS that may well top their competitors. This is how product releases work.
