YouTuber Claims 15-Inch MacBook Pro With Upgraded Core i9 Chip is Severely Throttled Due to Thermal Issues

You think Intel being late on the 10nm die shrink is unrelated to the 8th gen CPU running hot and being generally bad at overclocking? Interesting.
It's all fine and good if you dont mind losing warranty support. I use Liquid Metal in my laptop but I decided to do this after my warranty ended
Some need lots of power, some not as much... but that is beside the point. If the i9 throttles under heavy load, while the 2.2 i7 does not... buying the i9 is a waste of money... buy the i7 -- get the same performance -- save money. Will you be as dismissive if Anandtech's review confirms it - they are one of the best at it...
The question for me whether it is software or whether it is a thermal issue (hardware)... are the fans running at 100%. If they were running lower and throttling - then it might be a software issue. If they were running at 100% and the CPU is not reaching 2.9GHz... then people should not buy it... it won't add anything... other than bragging rights of having an i9.
this is an ancient problem
in my overclocking days I used prime95 for testing cpu stability and maximum heat at different clock speeds and voltages

no need for adobe premiere
putting your 4k machine in a freezer while running is a recipe for disaster (we do not want water to condense on the inside, do we)

You got it wrong. i9 is ready for a laptop with proper cooling. On the other hand MBP is obviously not ready for i9.
Do you have any example for that: any laptop with proper cooling that use i9. You mean the heavy gaming rigs? They are quite heavy though.
eGPU is a nice idea - dock in and get substantial video gpu power. While undocked you can be on the road with only one machine you can take anywhere with you.
BUT right now is not the time to invest in this solution. eGPU is weak sauce. You pay a hefty sum for the parts and the video card when you can get full pcie3 x8/x16 from a real desktop. TB3 is great and all but it isn't good enough vs a real desktop machine.
Eventually it'll get there but if you want real horsepower you don't design a laptop that is so thin. This is basic thermodynamics in which Mr. Ive's does not have a concept of. My noctua D15 actually isn't big enough (/s) but even then it's good enough. Sure the cpu's are all lower wattage but INTEL is done - their 14nm++ nodes are garbage and sitting on their thumbs for a decade didn't do them any good.
You can bet apple has their own designs in the works being tested. Sooner than later it's over for x86! The i9 is a waste of money inside a macbook.
It may only throttle with tasks that use both GPU and CPU (like Premier and FCPX). If it doesn’t throttle as much using only the CPU it will still be useful for those of us who only run CPU-intensive tasks.
Is the heat issue on solely Intel, or Apple’s cooling system? Or, a combination of the two?
The entire point of going i9 is for the performance/unlocked multiplier - which again is a big wtf in an apple machine. Inside a dell I would understand, but in any apple machine, it's a f-ng joke.
No one wants to pay for an i9 option to have their POS throttle down performance due to heat within minutes. That's like having to drive an aventador with 1/3 the HP because it overheats every minute or two.
This is coming to light because most macbook buyers don't understand basic thermal principles and never would bother to do anything on their laptops other than web surf. The ones that do understand they want real power in a laptop have moved past apple machines. The ones that are still stuck with apple machines waiting for the "one" have these issues to deal with.
Don't design your laptops so thin. Your fans are so pathetically small and there isn't an ounce of copper long enough to help aid in cooling that terribly designed i9 cpu.
This one - a six core. There are such heavy duty Windows gaming laptops you can verify in other (Windows and Gaming) forum.
The engine can perform, but the car doesn't have enough space for a large enough radiator.
Please correct me if I’m wrong: this thermal throttling issue on the new i9 processors is a inherent design and engineering problem on several levels:
- the intel chip heats too much when computing
- the thin laptop form factor is more difficult to cool down because of the lack of space for propper cooling system
- the MacBook Pro may be particularly badly designed for heat dissipation (CNCed aluminum)
Interestingly, the people who created the latest Razer Blade may have been well aware of this problem since they integrated a vapor cooling chamber to their latest laptop.

Mine laptop doesn't throttle and most windows gaming laptop doesn't throttle under full synthetic load (which is more stressing then video editing). I've put mine under full cpu AND gpu load at the same time and cpu stayed max turbo at around 83 c. Even if they they do throttle, they still manage to stay at or above base clock. Stop defending for apple and admit to the fact that they clearly didn't have enough cooling for a core i9 in such small form factor
I have a few
1 Dell Inspiron with Intel core i5 6200u with igpu
2 Acer Helios 300 budget gaming laptop. 8th gen i5 with 6cores and I believe a GTX 1060
[doublepost=1531892117][/doublepost]
Even if u look at the new Asus laptop with core i9 and a gtx 1080 (I forgot the name of that laptop) it still doesn't throttle under synthetic load.
What I would love to see is someone take the guts of this i9 and put it in a 2012-2015 Macbook Pro chassis. Curious how much of a difference this would make. I'm very surprised Apple didn't re-tool or do something to accommodate the necessary horsepower that the i9 delivers.
The current iMac design has the same cooling solution as the model that came out in 2013 (or whenever they moved to the thin frame version). I had a 2015 5k maxed out and it couldn't keep the i7 and radeon card cool. Apple makes one thermal design then shoehorns newer chips into them. We can't forget that they designed themselves into a thermal corner with the Mac Pro.... STOP MAKING YOUR PRO PRODUCTS SO THIN APPLE!!!!!

Ya. I didn’t get how the poster I responded to was saying Intel dropped the ball in some way.
"Pro" my ass. Dear Apple, please contain your "thin fashion statement" designs to the non-Pro line of computers.
That's cause they care about function over form. Sure the thing is a brick compared to a MBP but at least the purpose of it is for performance gaming.
These MBP are basically fake computers that pretend to be something else they are not meant for. This statement will offend the many apple cult zombies but please wake the f up and realize you just got bent over like sansa and your mbp performs like samwell tarly in battle. All show no go.
