Is this a news? MacBooks aren't particularly known for their excellent thermal design...

It's not just Apple, the thermal paste between the die and the heat spreader on newer Intel CPUs isn't getting good reviews either. Replacing the paste under the heat spreader is a lot more tricky though, and requires special tools. Why neither Apple nor Intel is opting for better thermal compound is amazing. Tests continue to CPU temperatures drop 10+ degrees (C) just by replacing the thermal compound. Even if they…
It may not hurt their margins much to use more expensive thermal compound, but it definitely won't help them in any meaningful way. These products are optimized for real-world bursty workloads that basically never hit a serious thermal limit that better paste could help with. Even on the desktop chips, delidding and replacing the thermal compound provides no benefit until you're pretty far into overclocking territory…

A 15" laptop's body could easily be absorbing 75 watts of heat from the sun, equivalent to running both the CPU and GPU of a MacBook Pro pegged at 100%. I think throttling in this scenario is a reasonable tradeoff, much more so than overengineering the cooling solution to handle it and thereby increasing cost, weight and bulk. Sit in the shade.
Isn't the operating temperature of a mac laptop max out at something like 35c ? That's woefully low for anywhere it gets hot, like Australia for example. It basically means that on a hot day in summer you cannot use your laptop unless you're indoors in air conditioned comfort. EDIT: Yes, I checked, the MacBook Air has an operating temperature of 10-35c and a storage temperature of -25-45c, which means that it's techn…
> you cannot use your laptop unless you're indoors in air conditioned comfort
Maybe it's just me being used to colder climate, but I feel that laptop's thermal throttling is going to be a relatively small issue if trying to work in sunlight when air temperature is +35C out there.
I'd really seek some shade even when it's merely +25C...

Apple can't make good keyboards anymore, are they even failing with their thermal paste now? I really don't feel these machines are professional level.

Half the issue is the shit TIM they use, the other half is the way they attach the IHS to the CPU. It's attached with a huge amount of sealant around the edges of the IHS and simply removing it will gain you a good 10c improvement because you're moving the IHS a few mm closer to the dye, combine it with good TIM and you're golden, replace it with some liquid metal TIM and you're off to the OC races.
I could maybe forgive them if this was an isolated incident on one generation of chips but this has been the case for about 4 years now.
I keep seeing thermal issues come back to bite some of the smartest companies with products designed by the world's best engineers. Everything from batteries to laptops to phones is severely affected by heat, and improper thermal design can lead to some huge issues. For example, the biggest thing affecting battery life is thermal load. The biggest thing affecting the maximum sustained power of a laptop or phone is th…
Don't forget the infamous Xbox 360 Red Ring of Death, caused by incorrect thermal management causing balls on a BGA package to lift from the board underneath as it deflected.

Same. It's hot, loud, and still never feels as fast as it should.
Loud? it's the quietest machine I ever had. No problems so far (9370 model)
It's quiet if I have it in "silent" mode, but then I might as well be using a 350$ machine, as far as performance is concerned.
Maybe you have a slower CPU, or they fixed the thermals in your model?
Here's a review from a dev who works at NASA: http://hrtapps.com/blogs/20180712/ Maybe the key point is he isn't running Adobe Premiere. The thermal issues in modern laptops certainly concern me, but they've been running hot for a long time now, and being thin doesn't actually change the surface area significantly.
Does Premiere use the GPU as well? The thermal system of the MBP needs to handle the combined thermal load of GPU an CPU.
Earlier quoted context omitted.
Well the single-core test is unlikely to max out the thermal loading on the CPU. You can see how the scaling from 4-6 cores provides severely diminishing returns, perhaps due to throttling.
Uh, it turbos in the 4+Ghz range. That is by itself probably going to blow the 45W thermal rating the entire chip has. My gut instinct says that macbook probably can't even dissipate that over a long period of time. The linked test seems to indicate the truth of that, and its not unusual for a mac product, the last one that could probably continuously dissipate the combined cpu+gpu heat was that crazy ugly mac pro. I…

Mine is the 9360 with the i7-8550U. In high performance mode, it's a hair drier. In balanced, the fan is a constant annoying whine if I have, for example, Webpack in watch mode, or am typing code quickly and keeping the IDE's language service active, or if any browser tab has any active JS at all. Basically if the CPU is at a reasonable speed and at 20% load, constant fan noise. It's quiet if I have it in "silent" mo…

The new chip has the exact same TDP rating as the old one. Unless Apple has made their thermal solution worse (highly unlikely) it is Intel that is fudging the TDP ratings.
The old chip pulled 33% less than its rated TDP in the real world. Also, lol if you actually think TDP means anything anymore. Over the last 5 years it's become a marketing number more than anything else. It gives you a vague category of what power consumption will look like... at base clocks, under a non-AVX workload. Modern processors will happily blast past their TDP by 50-100% if there is thermal headroom availab…
That sounds slightly made up. As you mention yourself chips pull vastly different amounts of power, and put off vastly different amounts of heat depending on workload.
> lol if you actually think TDP means anything anymore
Yes, it does not mean anything because Intel releases CPUs that exceed their ratings because they can't get their process right, which is my whole point.
