MBP 2018 - CPU Thermal Performance

[jinnyman]

For those who do not know, Intel 8th gen mobile CPUs are notorious for high thermal emission.
Even Windows gaming notebooks which are significantly bulkier with better performing active thermal cooling system are struggling with temperature.

I see the 2018 MBP form factor is the same as before, and I'm curious whether it can handle the CPU inside it. Especially 6core/12thread ones like i9-8950HK, i7-8850H, i7-8750H.

My 2016 MBP's 6700hq reaches 90~95 when running cinebench for example...and that generation was far from any problem.

So, spreading some FUD eh?

 

[jinnyman]

We shall see if I turn out to be spreading FUD or not. I personally hope that Apple is using some kind of improved cooling system in a new macbook pro such as vapor chamber so that it can run at full throttle without any throttling.

6 core processors will run hotter, its too early to say if the MBP has inefficient thermals.

This have been on my mind too. I think we will see more hear generated.

This would be interesting as I do not expect that apple have redesigned the board significantly. So if a new cooling solution is made there might be a chance it could be implemented on 2006/2017 model. If this was a possibility I would definitely keep and eye out and see what more brave souls than me could do fitting this into older models.

If you're concerned, add AppleCare. Problem solved. Since the Retina MacBook Pro (thinner chassis in 2012), everyone knows you only get discrete GPU + Core i7 if you don't mind a decreased battery life and a much hotter computer.

This will be no different I think.

When I open PowerPoint on my MacBook (2013 w/ discrete), the NVIDIA GPU springs into action and starts sucking away battery life. just one of those things and I know I can disable it.

I absolutely hate how idiotic the whole office suite is, even Word wants to use my dGPU, it has come to the point that I just turn on gfxCardStatus to make sure I am limited to iGPU.

We won’t now how much Apple has redesigned the logic board until iFixit does their tear down, but considering that Apple has redesigned both models to include larger processors, more ram, a T2 chip and a larger battery, I highly expect significant design changes to the logic board. Surely Apple is aware of the higher thermals of these newer processors, so I would expect there to be at least some effort to increase cooling ability of the MacBooks. Whether or not the changes they made were enough will be known in a matter of time.

I cant wait for ifixit to make the teardown, like Christmas, even the internals looks good. But I forgot about the T2, larger battery and such for a second. You might be right in that taking a bit more redesign then I thought

My thought exactly. Would be interesting to see iFixit's teardown on this model.
I'm sold if this thing can run at full load with little or no throttling!

I am guessing it can. This thing is a beast.
