Do i7 laptops throttle themselves when they are not plugged in ? What about Macbook Pros ?

I heard that most laptops when not plugged in, throttle themselves .

I just want to get some facts straight .

 

Most do, that 's why throttlestop exist.

 

That would increase battery use right ?

 

Low clock idle is something like 7w. Turbo idle is around 13w. That is for sandy 2670m.
You can keep it at low clock even if you use thorttlestop.

 

So with something like an i7-3632qm, I wouldn't see that large of an battery increase right ?

Is there anything I should be worried about if I un-throttle a system .

 

The power consumption number reported by ThrottleStop and most other monitoring software is intended to control the Intel Turbo Boost feature. It was never intended to be used for accurate idle power consumption monitoring. It is based on VID voltage and not actual voltage so there are times when it is completely meaningless.

If your CPU is spending a high percentage of its idle time in one of the deeper sleep states like C6 or C7 then there is no significant advantage to slowing your CPU down because it will be spending most of its idle time at virtually zero voltage anyhow.

I don't recommend using ThrottleStop while on battery power. Depending on the power draw of your CPU and GPU, if you try to run your CPU at full speed, you might end up drawing too much power from your battery which can damage it or reduce its life span. ThrottleStop was intended to be used when plugged into AC.

 

In my test using the Dell 6700, it does when using the external Slice extended battery. With the internal battery only, not so much. Kinda defeats the purpose of having an i7?

 

Well explained by the master.
Though the are some model that lock down the multiplier severely in addition to disable turbo. So monitor with ts and design by yourself.

 

Strange, I don't have a slice, but I noticed that on battery, my 3720qm was running at 3.3 GHz instead of 3.4 GHz, not that much of a deal in my opinion.

@OP, some laptops do throttle on battery, some simply don't, my G73 never throttled the CPU, it sucked the battery like there's no tomorrow, but there was no throttling.

 

I don't have a throttle on the m6700 on just battery either, can sure eat the battery fast if the CPU and GPU are maxed out though

 

Yeah, it does eat through the battery insanely fast, but at least it's great that you can run intensive stuff in a pinch.

 

Hence, the "not so much" in my post. I figured the .1 wasn't worth mentioning
