Tom Lehrer is brilliant. I occasionally confuse the hell out of people when I sing "Poisoning Pigeons in the Park" on my way to work (that or "I hold Your Hand in Mine", or "the Masochism Tango")

It is not enough to have a powerful engine, you've got to have a chasis that can handle that kind of power. A laptop cooler might help but it isn't a very portable system if you need to stick it in the fridge to use it.

Optional Extra Purchase

So what about the CPU throttling: I shall buy a man-sized refrigerator and work inside that. What's a little frostbite compared to using the latest and greatest MacBook Pro?

I've seen a video where they ran a MacBook pro from a freezer. Still only just pipped last year's range topper when chilled to -18°c....

Re: Optional Extra Purchase

So, thinking of the great Canadian Outdoors in January? Temperatures down to -40C not unheard-of? Good luck typing in woollen mittens. Over a decade ago there was a screen (which I associate with the IBM Thinkpad 600E and 600X models) which if used in extreme cold would adopt a pink (or perhaps magenta?) cast. Forever, though I think mine got less pink with time--and centrally-heated indoor use.

That's better than what happened to my Gameboy Pocket. The liquid in the LCD froze and broke the glass inside the screen. Never worked again and it was only about -30C that day.

These need a disclaimer that sustained maximum performance is not possible. The idea is sound that the processor can smash through a web page render or other short workload and then throttle back. BUT it's just not suitable for multi-hour rendering or gaming sessions.

" Frequencies may reduce over time as processor temperature increases."

Sustained performance seems to be "possible"...if you manage to keep the temperature below 50 degrees

That is the theory behind Intel's ultra-low processors like the m5-6Y57. It's a "finish the job as fast as possible and then go back to sleep" paradigm.

Which is fine for general purpose consumer laptops that follow that sort of workload - maximum speed while launching a program, or rendering a webpage, then go back to sleep.

However, these are 'pro' laptops, targeted at professionals doing video editing, rendering, other professional type workloads.

At the very least they should be able to sustain base clocks. But these laptops cannot even do that, they aren't just throttling turboboost, they are throttling their base clock speeds down.

Even if the exterior temperature was -100C you'd still be seeing > 50C on a CPU die, the cooling solution just doesn't dissipate the heat fast enough.

Fake news.

I haven't posted here in a long time, but I had to, because apparently most of you are willing to believe whatever other says, still, despite the biggest theme in news for the past year or two being that of fake news.

As an owner of the latest Macbook Pro with the i9, I've ran benchmarks on it, I've also ran it against the last gen top end i7 that my colleague has on server and compilation work loads that utilises every core and it's faster in all circumstances, both single threaded and multi-threaded.

Then again, any "pro" using a Macbook Pro would know to put in a fan control app, Apple is well known to prefer silence machines than noisy ones blowing out hot air, a bit like this youtuber and the rabble on reddit.

Who in their right mind would believe in a youtuber, whose job is to blow hot air.

@AC you do realise that you give some credence to the vlogger by saying Apple is known to restrict the fan in favour of low noise over high performance and then rubbish his claim of low performance.

Re: Fake news.

Right now it seems to be Youtuber versus Twitterer* as far as data points go. Which person you've never heard of, publishing their results via the internet's various platforms for the attention hungry do you most prefer?

I think Ars at least has pushed back its review of the new Apple machine in order to test the claims and provide something like an evidenced conclusion; I hope other outlets are doing the same.

* to save everyone the reading: he seems to allege the problem is in the use of Adobe Premiere Pro for benchmarking, by posting figures that show it takes almost 2.5 times as long as Final Cut Pro X to perform the same task on the latest MacBook Pro. I think he's suggesting Premiere isn't well-adapted to modern processors. It's Twitter though, so mostly the word-based version of a Rorschach test.

Re: Fake news.

Actually, in my mind, the reverse astroturfing implied by the grammar in "I've ran" gives the vlogger even more credence. By not knowing your language, you discredit all of your other thinking.

i9 works great in a suitable chassis

Check out the MSI GT75 Titan.

4.5 kg full of ventilators and heat pipes to keep things cool. And apparently it works.

Perhaps Apple and Dell can learn from this design.

Did I mention the Titan has *two* power bricks?

Re: i9 works great in a suitable chassis

This reply is 100% spot on, any laptop being sold as high-end gaming rig, and is not at least one inch high, will suffer from performance reduction due to heat constraints.

People buying thin, but supposedly fast laptops, fell for a trap, one can not beat physics.

MSI understood this when designing their GT-series gaming laptops, they stay cool and fast.

The extra cooling capacity due to the height, also reduces high and noisy fan speeds.

Laptop coolers won't be enough

No gaming laptop I've seen so far has been able to combine performance, good cooling and relatively low noise from the cooling solution.

Even with an external cooler it's not going to be much better, all this throttling does is expose how unsuitable the laptop chassis is for the CPU it houses. They can fudge a fix if they want, bottom line is that it'll still throttle and you'll still fail to get the full performance out of it for any sustained period because of the fundamental laws of thermodynamics.

It needs a Blowiematron.

Saw those Canadian loonatics (lol) at LinusTechTips "install" an 11,000 RPM fan into a laptop to get adequate cooling for their Core i9. I think they also de-lidded it and added better thermal paste (remember, Intel's ease of assembly trumps your cooling needs). Anyway, it may run at 120dB+, but pushing several cubic feet of air a second seems to do the trick.

Remember when laptops came with "mobile" processors because manufacturers knew performance CPUs wouldn't operate efficiently in that enclosed, often battery-powered chassis? I guess marketing hype outweighs common sense these days.

Where is the fat cat businessman smoking a cigar and counting his money icon?

unless I am wrong

This CPU is the one that you have to get on a 512GB or up SSD MBP. For... $600 CAD extra to the 256/lower CPU model. That’s mucho $$$$ for 256G of disk, but hey, you get a faster CPU. Oh, wait.

So, if you want a “pro” machine without a thermally crippled CPU, that’s 256GB disk space max, bub!

Least Apple should do is revisit their SKUs and ship reasonably sized disks with CPUs that run normally within their TDP budget.

you’re a right genius, aintcha?

i thought about saying we were getting high prices and, at best, reasonable hardware (if you’re not often @ sustained peak CPU loading in your use that it)

but then I thought charitably that it’s obvious in context.

not to you i guess.

@JLV & "I can make do with either of the 2 choices below:- high price/flawless hardware.- reasonable price/reasonable hardware"

This is Intel hardware so high price/broken hardware

Also best not to mention money to AppleFools®, they didn't opt for Apple because they understood what they were buying, the purchase was only to allow them to associate with other AppleFools®.

Personally I think the Wannabes should revive fur coats (wool being too obvious even for them), at least then their social entry ticket will have some practical value to the owner come the winter.

Yes - you're wrong.

The 512GB (and up) 15" macbook Pros come as standard with the core i7 processor.

You only get the core i9 one if you specifically specify it as a build-to-order option
