It can't handle the 750m, it actually drains power from the battery if you try to use the 750 at max.

You're right. And the throttling because of that really hurts performance.. Some people say a 650m can get up to gtx 660m levels.. that's funny :p

Never said it is. Still, peak power consumption is limited by the TDP (by design).

TDP should not be used as a method to rate a GPU/CPU's power consumption.

Here is a 3840QM with a 45watt TDP drawing 66.9 watts..

TDP is just used as a spec for designing heat sinks that can properly dissipate heat without throttling. Apple usually misses this memo (or maybe they did on purpose by bringing down the TDP by using a lower wattage power brick?)

No, your CPU has a boost power which it runs at briefly. Once thermals and other bios settings kick in it will drop down to 45W sustained.

It will sustain 55+ watts. Just gotta have a cooling system that actually works. Intel also has a feature called configurable TDP which can up the TDP if the cooling system can sustain it. So maybe that voids my argument haha

That screenshot above is when the CPU is in 58watt (upper TDP mode) and is turbo boosting to 66 watts. So when it's not turbo boosting it'll hover around 55-56 watts for as long as it wants given the temps are below 96c (which is what clevo decided is throttling and not 100-105c which is the stock intel spec) and this is usually forever lol

Hmm. Well if you are messing around with the TDP rating then you can hardly complain about intel not following spec.

But then that's a clevo and may be modified for overclocking, etc.

My devices don't do that.

3630qm

Activate prime 95 -> 42W
Activate furmark (igp) -> 57 W
After 5s drops down to 45W. CPU speed drops to base (2.4 ghz).

I guess it does void my argument. so ignore me haha. Configurable TDP is an intel spec thought still. Still off topic I guess lol I switched to an Asus 14 inch G46vw and it does the same thing.
