Identical CPU's performing very differently

[DnFx91]

Can anyone explain these i7-6820HQ scores ?

 

Am i really to believe that simply being in a different laptop causes this much variance in cinebench score ? like is it a thermals thing ?

 

one is in a Dell Precision 7510 and the other is in a Dell Precision 3510.

I'm guessing that in the 3510, it is set for 35W TDP and in the 7510 it is set for 45W TDP. Maybe.

didn't know that was a thing, will speccy tell me ? or CPU-z ?

Just checked Dell itself. Clearly says on 3510 specs, 35W and in 7510 specs, 45W.

can't believe i never knew that, i guess it's unchangeable then ? and preset in the factory based on that laptop's unique cooling solution ?

Exactly.

hmm, i feel cheated lol. Is it a setting that's applied directly to the CPU itself ? I mean, they are just PGA packages right ? if i swapped the CPU's between the 2 laptops, would the same thing happen, or would the 45w one run at 45w in the 3510 ?

 

Or does the mobo decide ?

It's soldered to the mobo, Flip Chip BGA. And it is the same chip in both of them. Mobo decides.

oh damn, when did laptops start going BGA then ? all my other precisions going back to 2nd gen intel cores use PGA and i swap them out all the time. 

Dell using BGA saddens me

Precisions are DTR laptops, big bulky machines. Anything thinner than those have been using BGA since forever.

Yeah thats what i mean, i have some dinosaur monster m6600 precisions, 17 inch, still pga :-s

You might try the Intel Xtreme Tuning Utility.  It may be able to change some of those parameters.  I've never tried it on a motherboard that doesn't allow overclocking itself. 

However even if it does work, the laptop may not have a cooler capable of handling the extra heat.

probably just leave that one alone then  thanks for the info though, learnt something new today
