Genuinely curious: I don't work in the space of CAD, video editing or any other field that people tend to use to justify the MacBook Pro's ludicrous pricetag that has some shiny numbers on the tech specs sheet. Do these really do anything a sufficiently equipped laptop from anyone else can't? Plenty of options with latest gen Intel and Nvidia 10xx series are out there for less insane prices. Granted, I don't see many…

Yep Its just a million little details that make it such quality. The awesome UI of the OS. The trackpad is the best trackpad I've ever used. Every other trackpad feels clumsy after using one. The fact that it's a TRUE linux machine not just retrofitted Windows linux. The fact that everything just works. The chance of getting a virus is incredibly small. The time saved in troubleshooting is worth the price. Operating…

The "retrofitted Windows linux" is more Linuxy than the Mac (and both suck compared to an actual Linux OS).

Yeah but that's like buying a race car and being upset that it's throttled at 300 mph. 99.9999% of people will never go 300mph..unless you're using it in a very specialized way.

But it's supposedly _slower_ than its predecessor in sustained situations like this. What's the point of having a "more powerful" 2018 machine over the 2017 if, when trying to use that power, you end up worse off?

For most users, sacrificing some sustained performance for the sake of higher burst performance is absolutely the right choice if such a tradeoff is possible. People who keep the CPU at 100% with a multi-threaded workload for minutes on end have a workload that requires a desktop form factor. For the other 97% of users, the CPU will spend far more time idle than fully-loaded.

I often work outdoors, and merely being in sunlight makes my 13” MBP go to max fan speed after about ten minutes, and insufferably slow after a half hour or so.

That doesn't strike me as particularly noteworthy/unexpected.

You don’t think it’s unreasonable that a laptop should work in daylight?

It's summer now and as soon as I plug my MacBook Pro 2017 in to charge, it starts throttling itself due to the heat of the charging battery. Same thing happened to the 2012 I had before. These things just don't have adequate cooling.

Do you have a way to monitor or measure the CPU throttling on macOS? I've found Intel Power Gadget [1] which looks like it might help, however, I'm not really sure what these graphs should look like when throttling vs not. [1]: https://software.intel.com/en-us/articles/intel-power-gadget...

That should work for revealing throttling -- you will see that it tops out at 1.1 GHz or something.

I’m sticking with my 2015 15” until it bites the dust and then probably getting something else if Apple hasn’t figured this out yet. Even there software is degrading. I feel like I’m doing better by not running updates (I know this is not so, for security reasons, but...)

My favorite is the latest Air (years old now) which doesn’t even have a retina screen yet, a perk in my book. I could watch Netflix on my bare stomach with my Air. Latest Pro is quickly too hot to handle. Of course not the only issue but the computer never bounced back from that first impression. The dedicated gfx card doesn’t even seem to run games like Civ 5 better than my Air which I’m guessing is due to all the e…

> I could watch Netflix on my bare stomach with my Air

Don’t try that with a first gen Air. It had a very significant problem with thermal related issues. Several times a week it’d get so hot I could make pancakes off it, the rest of the time it was in a throttled state. Was a very common problem among folks I worked with (albeit mine was a personal, theirs was a work machine) too.

Yeah but I don't think buying a race car and use it to race should be considered as "using it in a very specialized way".

I think the better car analogy here would be buying an expensive luxury sports car and being disappointed that it couldn't keep pace with a real race car on the track.

No laptop can be an equal to a real workstation unless you don't actually need a workstation to begin with.

I guess the key is that it under-performed vs last model's i7... not that it has thermal issues. I would think most laptops have some level of thermal trade offs.

The key is that the thermal issues are so bad that it causes it to underperform against the last models i7.

Anybody knows if Apple's ARM chips (iPhone) have better thermal efficiency (watts/GFLOPs) than the chips in this latest gen? If this is the case, I think it's just a matter of time for Apple replacing Intel with their own custom ARM chips.

You can't really compare ARM and x86_64 chips. I'm going to use a crude example. Think of the ARM chip being one of those USPS Trucks ( https://upload.wikimedia.org/wikipedia/commons/3/37/Small_US... ) while the x86_64 is a F150 pickup. Both can drive around and transport things, but the USPS Truck is purpose build to deliver mail, stop and start frequently, and be reliable. It does a few things well. On the other ha…

What? They're CPUs. They're designed to run instructions. Intel's chips spend more energy on the really fancy stuff like huge reorder buffers and extensive speculation. They get higher IPC at lower MIPS/watt. An i7 isn't going to run iOS more slowly than whatever Apple calls their latest ARM SoC. It _is_ going to blow its lid without a big ole heatsink brick on there and a fan too, which is why smartphones use ARM cores designed for efficiency.

P.S. if anything, ARM is the "general purpose vehicle" in your analogy. x64 is all about high throughput and high power on a chip you buy and plug in. ARM is the one where you can get an architecture license and customize the shit out of it.

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.

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.
