I watched multiple videos from “famous,” youtubers concerning this issue, and not a single one mentioned fan performance, except on Aaron from Zollotech, who measured dB, a subjective measurement depending on microphone sensitivity and placement of said microphone, but did not include actual fan speeds.
yeah, meaning its really throttled hard.
It could be. Some other members have pointed that out, but the general consensus is that members here ignore it could be a first-shipment issue, a fan issue, a software optimisation issue, or the fact that it’s actually a PowerBook G5.
There are only two options:
As have I. I said much, much earlier in this discuss we need to wait for more information.
My "hypothesis" was based on something less than 100% (I used 80%)
The profile for the computer is not necessarily (and often not) the same for each computer.
you propose capping cpu usage? then single core performance suffers.
I'm not proposing anything, just merely wondering. With that said there are scenarios where software cannot take advantage of the full capability of a CPU. Multithreading is one such area. An example:
But then you have other issues. My friend (Window Dev) is constantly fighting with his Windows and Microsoft. In fact, he got so fed up Windows update that for work (not gaming) he runs his Windows with everything installed on VMWare on a bare-bones Windows so that every time Microsoft bricks his computer he can just roll back and continue. Then the last update Microsoft caught on (1803) and made it so that he was no longer able to log in. Then, of course, there is just plain the inattention to detail and they are constantly using different standards (different font sizes in sidebar, slightly different shade to certain standard elements, changing standards but never fixing to make sure you change things to that new standard in a consistent way, hiding things in plain odd places (and sometimes moving them around between minor updates)... all of which might seem minor but once someone points it out to you your (or my) OCD side takes over and it becomes very irritating. I have worked in software development long enough that you sometimes are so focused on making the hard bits work perfectly, that you sometimes forget to go back and focus on the small bits... that combined with compressed schedules because someone in marketing thinks that the date should be some random date for no reason without consulting development and give assurances to customers that it will be out on that date (which often will freeze the date because now they are making dependencies on it).
If you do test it, and it throttles even slightly... try installing a fan controller (it might not be customized exactly - but usually it will work even if it just throws the fans into permanent high mode until you reboot it
Apple's new 15-inch MacBook Pro can be upgraded to include a 6-core 2.9GHz Intel Core i9 processor that has demonstrated impressive performance, but one YouTuber is warning customers away from purchasing it with claims that the MacBook Pro chassis can't provide sufficient cooling for it to run at full speed.
Dave Lee this afternoon shared a new video on the Core i9 MacBook Pro he purchased, and according to his testing, the new machine is unable to maintain even its base clock speed after just a short time doing processor intensive work like video editing.
"This CPU is an unlocked, overclockable chip but all of that CPU potential is wasted inside this chassis -- or more so the thermal solution that's inside here," says Lee.
He goes on to share some Premiere Pro render times that suggest the new 2018 MacBook Pro with Core i9 chip underperforms compared to a 2017 model with a Core i7 chip. It took 39 minutes for the 2018 MacBook Pro to render a video that the older model was able to render in 35 minutes. Premiere Pro is not well-optimized for macOS, but the difference between the two MacBook Pro models is notable.
Lee ran the same test again with the 2018 MacBook Pro in the freezer, and in cooler temperatures, the i9 chip was able to offer outstanding performance, cutting that render time down to 27 minutes and beating out the 2017 MacBook Pro.
As Lee points out, thermal throttling is in no way unusual and it's seen in all manner of laptops and mobile devices from a range of manufacturers, but he says that "this degree" of thermal throttling is "unacceptable."It's not clear if there's something wrong with the MacBook Pro with Core i9 chip that Lee received, because this kind of throttling is likely something Apple would have tested for and not something that other users have reported at this point.
Because this is just one data point, it's not enough information to reach a conclusion about the i9 chip available for the 15-inch MacBook Pro, but additional testing will certainly follow to shed more light on Lee's video. We have asked Apple for comment on Lee's findings, and will update this post if we hear back.

That is correct, if you have more than 8 cores or threads (can't remember which one it is) it will not perform at maximum... you literally have to basically peg it against a defined set of 8 ... and if you have more power just run multiple copies. I think it is actually in the lib (x264/x265) that Handbrake relies on (and other things). You cannot just run multiple copies without doing that or they will just step on each other and the performance for each copy will suffer.
So whereas other companies get the accountants breathing down the necks of the engineers, forcing them to cheapen up the specs of their machines, Apple is getting the fashionistas doing the same thing, saying something like, "You have to make it paper thin, and as long as the user gets the impression of something happening fast for a second or two, they won't notice that the rest of the task is no faster". Smoke and mirrors, and of course it fails once subjected to an objective analysis.
