Is this throttling in the chip itself? Or is it something that e.g. Linux (the kernel) needs to be taught specifically for make/model? Or some combination of the two? And is it possible that the in-chip limiter is more of an emergency limit, and hitting it regularly can result in long term consequences if the kernel doesn't do aggressive enough limiting? I just see really different behavior with heat, fans, and kerne…

In the source video, it shows that the chip is downclocking to 2.2GHz under sustained load. There is nothing any software can do about that as that's hardware doing it.

The OS can govern how the fans spin up, but all CPUs will throttle down when they hit a predetermined temperature.

I develop on a macbook pro for 12 hours a day. Have a bajillion chrome tabs open, 2-3 ides open, sequel pro, photoshop, slack/skype, utorrent, spotify, and more.... My macbook pro 2016 i7/16G doesn't even skip a beat. Unless you're doing 3d graphics or Machine Learning or something...I think for 99.9999999% of POWER USERS a throttled i9 with 32 gigs of RAM is plenty for the year 2018. This throttle issue in my opinio…

I think the main quibble is that the laptop can't even hold it's base clock speed without throttling.

Under sustained load. That's the key part here.

All three 15-inch Mid 2018 MBP configurations benchmarked are at the top of Geekbench for multi-core, only behind iMac Pro and Mac Pro models [1].

Here they are in isolation compared to the 2017 and 2016 15-inch models sorted by score descending overall:

    | Model                           | Configuration                            | Score |
    |---------------------------------|------------------------------------------|-------|
    | MacBook Pro (15-inch Mid 2018)  | Intel Core i9-8950HK @ 2.9 GHz (6 cores) | 22547 |
    | MacBook Pro (15-inch Mid 2018)  | Intel Core i7-8850H @ 2.6 GHz (6 cores)  | 21266 |
    | MacBook Pro (15-inch Mid 2018)  | Intel Core i7-8750H @ 2.2 GHz (6 cores)  | 21096 |
    | MacBook Pro (15-inch Mid 2017)  | Intel Core i7-7920HQ @ 3.1 GHz (4 cores) | 15550 |
    | MacBook Pro (15-inch Mid 2017)  | Intel Core i7-7820HQ @ 2.9 GHz (4 cores) | 15251 |
    | MacBook Pro (15-inch Mid 2017)  | Intel Core i7-7700HQ @ 2.8 GHz (4 cores) | 14374 |
    | MacBook Pro (15-inch Late 2016) | Intel Core i7-6920HQ @ 2.9 GHz (4 cores) | 14134 |
    | MacBook Pro (15-inch Late 2016) | Intel Core i7-6820HQ @ 2.7 GHz (4 cores) | 13706 |

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.

Earlier quoted context omitted.

This! They ought to rename it, and actually sell a professional laptop.

"Pro" is a pretty broad term. I suspect the MacBook Pro is powerful enough for most professionals who need a computer to do their jobs. I use one professionally for software development, and it suits my needs just fine. Sure - there are some professions out there that require more power than a MacBook Pro can offer. But is it really fair to say it's not "Pro" just because it can't meet the needs of 100% of all workin…

> But is it really fair to say it's not "Pro" just because it can't meet the needs of 100% of all working professionals?

Apparently it cannot even meet the needs of its own spec sheet. It gets throttle back below its base clock speed according to the video. That's the real issue.

Apple claims this is "More Pro" but it turns out to be just more of the same from Apple lately. One issue after another.

I use smcfancontrol on my imac to force the fans to do their thing. The problem seems to be that osx prefers throttling over turning the machine into a vacuum cleaner. For me this is the only way to play games. Without smccontrol throttling kicks in and the fans never go on fully.

The Macbook Pro has a great 100m sprint, but it can't complete a 1km race without crawling across the finish line.

Geekbench takes a few minutes to run. If you ran it back to back to back without letting the laptop cool down, you'd see different numbers.

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…

> Operating system upgrades are like 30 bucks vs the 1-200 dollars of every new windows release.

When was the last time you upgraded macOS? It's been free for several years. :)

Also, to be fair to Microsoft, Windows 10 is supposed to be the last version of Windows, so you should only have to buy it once and never upgrade again.

OSX, as sibling pointed out, but let me be much more specific:

- iMessage

- excellent integration between Contacts, Maps, iMessage, Mail, and Spotlight

- Mail.app, the best desktop mail client (IMO)

- Siri > Cortana > Whatever tarball you are expected to run autoconf inside of to get your linux box to act like a mac from the 90s

- excellent HiDPI support (neither Windows nor Linux have figured this out yet)

- plug and play external display support

- configuration-free lid switch sanity

- configuration-free trackpad sanity

- Lack of vendor adware (Windows obvs, did Ubuntu ever remove those Amazon search things?)

- painless FDE (extremely important)

- good fonts

- iOS development possible

- the most common modifier key is where my thumb can reach it and is not overloaded with the unix modifier key (is ctrl-c copy or SIGINT?)

- copy and paste work between apps using consistent keystrokes (windows figured this one out, linux not so much)

- less malware than windows

- an order of magnitude better a11y than anyone else in the history of OSes (it’s literally not even a race anymore, Apple is so far ahead here)

Finally, in not-OSX:

- build quality, even with keyboard and thermal issues, is still simply a head and shoulders higher than everyone else

The only people who could reasonably challenge Apple’s level of fit and finish from an OS perspective are Google, which is why I carry an rMBP and the 16gb Pixelbook. ChromeOS these days is a fucking marvel, up there on quality par with google search before answer cards, google assistant, and google maps. It’s a major achievement and is the first actually workable/usable Linux desktop.

Were the benchmarks run on a cooled room? Some years ago, as a student, I paid $$$ for a Toshiba with 4 cores and hyperthreading, and I could only run them well on the winter or in a very cool room. In the summer it would reach 100C and constantly throttle, so I do think that temperature is a key issue, sp. now with slimmmer laptops
