I have been using a laptop with 2.3 GHz processor clock speed so far, which has been sufficient for my needs (which peak at some intensive programming, e.g. ML).
I’m looking for a new one right now, and saw a laptop advertised as having “1.0 GHz, up to 3.6 GHz with Turbo boost”.
I have no idea how Turbo Boost works. I don’t understand what it means for the processor to automatically ramp up its speed when intensive programs are running — as far as I can tell, any program would work better with a higher processing speed.
(When) can I expect 3.6 GHz performance from this CPU? Or will it be more like running a laptop on battery saving mode?
Answer
1GHz is the guaranteed worst case.
My laptop is 1.3GHz but boosts up to 3.6GHz and under load floats somewhere around 2.4-2.8GHz.
It all depends on ambient temperature, heatsink, other heat sources such as battery charging (which causes heat) fans, power usage and other things.
You’ll get the “full” boost speed on small bursty single-core tasks and somewhere between the “normal” 1GHz and full boost speed during normal operation.
