CPU speed

[Guest]

Hi,

I've got Lenovo y720 gaming laptop,

it has an intel i7 7700HQ @2.8GHz CPU,

but when I check performance, it's running at 3.6GHz, can anybody explain?

thanks

Probably a combo of Turbo Speed + Windows Task Manager not always reporting frequency properly.

 

Why don't you want it to run at a higher speed..?

That's called Turbo-Boost. Basically the old way that CPUs worked, before the Core "iX" series and such, was that your CPU would stay at the clockspeed it's listed to run at. It would go lower to save power temporarily until used again, but it wouldn't go any higher than that speed. Nowadays, most processors are listed to run at a certain, baseline clock rate, in this case it's 2.8GHz, and have a set amount of power they can use to "boost" higher.

 

It's designed to take full advantage of the CPU when certain programs, like older games and such, don't use more than 1 or 2 cores. I believe your CPU will boost to 3.4GHz across all four cores at full load. Just consider it extra performance!

I don't think he doesn't want it to run higher, he's more just confused as to why it is running higher. TBH, if my CPU was overclocked in my laptop without my permission, I'd be concerned too!  Gotta remember that most people don't understand this boosting thing most processors do. Heck, I have been laughed at because my laptop CPU only claims to run at 2.2GHz, when in reality it boosts to 3.5GHz under full load and stays within TDP limits!

didn't say that, I'm pretty happy with it, because I thought 2.8GHz was the maximum speed it can perform.

thanks !

nice thing to know about, and yup I thought it was overclocked without my permission at first.

thank you!
