MacBookPro 16-inch has current noise, cpu turbo frequency noise？

So Mac will wok slower in single core mode. So programs which in some places of execution(or they just constantly use one core) can switch to one core will work slower. Example with turbo boost off - geekbanch show nears in single core mode650 points, but with turboost is on - 1050 points so big difference for single core mode. But we can admit that many programs use single core mode - if we can hear sound - with the turboboost on, so turn off turbo bust is not an option because it reduces performance by almost half for one core.

Also you can reproduce coil whine(it's not very loud in exactly such case, but you can still hear it) by starting type letter by letter in spotlight - and you can hear sharp noise when letter was typed

The coil appears when the frequency jumps sharply from small(1000Mhz) to very large(3600 or 4000 Mhz) and the greater the difference, the more you can hear the coil whine. Why this happens - apple puts poor quality inductors that produce vibrations

I think it's possible - it's necessary to reduce the difference between the frequencies as much as possible and then either the processor will work all the time at rest at higher frequencies (bad for battery life) or it will cut off the turbobust and then the processor will work at lower frequencies and will not overclock much (bad for performance).

I've got MBP 16 i9/32Gb/1Tb/8Gb and the same problem with it. During my own "investigation" came to the same conclusion - the source of squeaking sound is the Turbo Boost, not the SSD. And if it was just scratching, this could be tolerable, but in some apps it's like ultrasonic dog whistle , and brings really uncomfortable feeling. Hope that Apple solves this with firmware update like you proposed!

This is hardware issue and this issue cannot be fixed with firmware update - so there is two ways try to live with this or get money back. Two times made a request to apple about motherborad replacement - apple said that noise it is typical for electrical devices - so apple refuses to fix this problem

Turbo Boost boosts the clock rate on small number of processors when the rest are idle and the processor chip is comparatively cool. When many processors are in use, such as doing high-end work, Turbo Boost is not available.

If the noise bothers you, there are third-party utilities to turn off Turbo boost. The decrease in real-world performance is very small.

My previous MPB 15 2017 had a lot of problems with keyboard, but it was completely silent. So I bought this one as a "fixed version" of previous generation and I guess it would be such a shame to turn off turbo boost in 4000$ machine and loose half of it's performance.

Geekbench, Turbo on: Single core - 1058, Multi core - 6358.

Geekbench, Turbo off: Single core - 647, Multi core - 4280.

Thats'a huge decrease in both single and multi core modes.

Real web project compile:

Turbo on:

Version: webpack 4.42.1

Time: 4754ms

Turbo off:

Version: webpack 4.42.1

Time: 6704ms

That is a completely artificial test program. It has NOTHING to do with "real-world performance" which is what I cited.

Try it yourself! If you hate it, it's just a setting to undo.

If it makes the machine quiet enough and does not kill "real-world performance", you have a work-around while Apple and Intel mull over a solution

Well, I hope there will be a firmware solution. I know we can't break the laws of physics with hardware, but I believe there is a way to configure the OS core to trigger these Turbo Boost spikes "smoothly". Flatten the curve, you know. As to me, it would be ok to get a completely silent device as a trade off for 5-10% performance. Not 40%, as with Turbo off.

Paradoxically, traditional Software Development is one of the few intensive activities that is still largely single-threaded.

At this writing, that single-threaded performance appears to come at the price of some noise.

Have you optimized everything else you can? Like I/O? Sources and Destinations on different drives, and both different from the boot drive?

paradoxically, how the QA department at Apple works - how many years in a row do not find such defects - Apple seems to have run out of footage - or they find all these bugs - well, the management says that they would still start selling - people will still buy

I also has micro sluterring and freezes every 2-3 minutes when i am on intel hd graphics 630 - when i am on radeon graphics card - micro sluttering go away - it is still about apple QA and last year products quality

Be careful with these remarks about publicity of the problem - apple has already removed my similar post - they are afraid of publicity because I suspect they will have to replace the entire line of macbook pro 16 - they are all with such defects judging by user feedback
