Apple M1 COVID infected notebooks - Air 2020 ARM and Macbook Pro 13" ARM!

New predictions

Apple is preparing to release two models with a screen diagonal of 14 and 16 inches, which will have a flat-edged body "similar to the iPhone 12" without any curves of current models. This will be the most significant design update for the MacBook Pro in five years.

The company will be phasing out the Touch Bar, returning to physical function keys. Apple will also return the MagSafe charging connector, mostly due to the sheer number of burned out USB-C ports. The updated MacBook Pro will have additional ports and possibly even memory card readers. Most users will not need to use additional hubs to connect other devices.

It is also reported that the new MacBook Pro models will use only Apple branded chips - configuration options with Intel processors are not provided.

The new MacBook Pro models are forecast to ship in the third quarter of 2021.

Apple vinegar for everyone!! Was a fine wine.

10bit full RGB may be only for Mac Pro range.

All M1 computers have hardware issues with output to monitors

Some problems have come to light in Mac products equipped with the new CPU "M1" announced and released by Apple in November 2020.

EIZO Co., Ltd. quickly released information on compatibility with its monitors. It is said that there are cases where gradation skipping occurs in the video output from the Mac side equipped with M1. It is also reported that there is a partial workaround for this problem, but only for certain products.

According to EIZO, if you connect an external monitor to a Mac equipped with M1 with an HDMI cable, you may not be able to see the original color and color gradations that monitor can show. It is problem common for any monitors.

The cause of the problem is that the video signal from the Mac equipped with M1 is always output in a format that uses compression, called YUV / Limited Range, instead of RGB full-range output.

The YUV output of the M1 equipped Mac has less gradation than the full range, so it may be because the original reproduction cannot be obtained even if this is converted to the full range.

The Mac product equipped with this M1 does not solve the problem even if it uses a USB Type-C connection or DisplayPort conversion connection.

New interesting rumors

Development of M1 started three years ago. And two years ago after internal presentation with initial tests and information Apple had been ORDERED by their three leading investors to fully move into proprietary ARM Mx chips. Initially none of managers supported this move, as they wanted to move only Air lineup to ARM and even for them keep using x86 chips for some models.

Investors hope that by moving to ARM they will be able to fully close ecosystem and ban application they don't want to see on new Macs. This stage will come in 2021 and finish in 2022.

Apple sent note to developers in at least 2 big companies about their CPU plans

Apple told not to expect rise of single core performance, instead it can drop up to 20% in newer chips in new notebooks. Number of cores will rise and Apple asked to focus all optimizations of this. Also Apple will increase number of closed CPU blocks used for various acceleration things, including use GPU for calculations. Not all developers will be getting full detailed docs on this, company must be inside tight circle to sign special agreements.

With ARM chips Apple will use approach they long dreamed about - sign set of secret private agreements with largest software developers to help eliminate small fish as they are stealing Apple money, by destroying small and medium companies Apple plan to make exact copies of their software and later sell them as part of their cloud subscription. Developers hear this talks happening quite often lately inside Apple software teams management.

Sample of second round marketing

Several dedicated people worked with Linus on this.

Note how it is always PugetBench thing that had been made with close Apple participation (of course Puget will tell you otherwise).

Remember - always ignore any video or photo related benchmarks from Puget Systems.

Interesting rumor

Apple plan to manufacture all 3nm (and later 2nm) computer and smartphone main LSI in the US as soon as TSMC factory will be up and running. Also all core suppliers of TSMC factory had been asked to also move production to US.

Apple can also organize big investment into TSMC and suppliers that can reach $50 billions.

Within 5 years Apple will totally leave Taiwan. Main reason cited is region rising instability and risk of Chinese invasion.

Leaks inside Apple

AMD secretly negotiates with Apple considering 5nm TSMC process as developers tell.

Investors and Apple management ask to shift new 5nm Zen at least one year, preferably 1.5 year. Such way Apple can gain more market share and as each Apple product is more profitable it is also financially also more viable for core investors who control both companies.

Apple notebook team working on models with AMD chips still alive and well. Yet we won't see them within next year.

Adobe has released an Arm version of Premiere Pro for macOS, allowing owners of new Apple Silicon M1 Macs to run the video editing software natively.

I think the point is to do some testing after many have suggestively written that these computers would "handle a 4k timeline". On the other hand I myself have evaluated similar possibilities (despite a not excellent CPU in the Macbook Air) in the past, with the old models that could connect to eGpu. Many of the slogans said are denied, or at least questioned, by this test.

@miko

Why this guy uses Air and complains that it overheats? Air is not made for any heavy render, despite paid reviewers claims.

Another interesting test

@VK The thermal envelope risk are the first points you make which aren't mitigable. So it's a dragster, it runs fast the quarter mile race. OTOH this is the use case for the form factor these chips launched in. Color me worried if the future ARM iMac and Mac Pro will run the same thermal risk. I think we'll see some advanced cooling on those, embedded in silicon. The technology exists, but maybe not for 3/5 nm processes.

More on M1

Reusing A12X packaging line that originate from internal LSI design failure.

Bad thermal performance with cores concentrated in small area, during stress temperatures can reach critical 105-107 degrees.

Complex interconnects

Lot of blocks

@Readbook

100 degrees on 14nm Intel chip and 100 degrees on totally integrated 5nm M1 with DRAM dies on top are not even remotely comparable. Such complex 5nm dense chip degradation will be 10-15x compared to simple Intel chip. If you look around at servers and GPUs that are used for everyday NN training - it is highly advisable to not go above 90 degrees, 95 degrees is considered top allowed temperature since 7nm chips generation.

This is first.

Her point was that people who got notebooks from Apple performed tests such a way (according to Apple guidelines) to make impression that M1 is totally different, always cool and fan will be silent even during rendering. It is the case only if you do specific settings test.

Readbook

I used this tool on several macbook pro 15.2 2012-2015 years. All these laptops heat up to 100, then they overclock the fan and continue to work like that. I think all macbooks from 2012y.o. doing the same thing. What's so bad about m1 also reaching 100 and slowing down? Even in this mode, it just does some things faster than other Intel laptops.

Btw tool that she uses is very interesting

@miko

This is first sane video about throttling, instead "it is miracle" things made by non tech guys.

You really see task that load cores and GPU and cooling sucks.

You are getting 100 degrees CPU, you get 7200 RPM fan sounding like jet and it is literally nothing you can do.

To make cooling better Apple needs 2 fans and increase thickness (to use thicker fans).

This is effectively how good Windows notebooks are designed.

Tests for thoughts

Vitaliy_Kiselev

Back to Apple policies, info from medium size Youtube channel

For all video applications reviewer must use only formats that have support of build in M1 hardware accelerators. Tests that use other formats are allowed but must not take more than 15% of time compared to accelerated formats and it is preferable to not make any charts and focus on them. Tests that use supporter format but with parameters that lead to disabling of hardware acceleration are not allowed and can be done only in addition videos or separate texts.

Apple also provide detailed instructions on how test export time in FCP X (test is designed such so it allows FCPX to render before export start, also all transitions and effects are designed to not allow M1 cache size overflow or to use all CPU cores and GPU at the same time).

Not following Apple guidelines considering video applications result in APple stopping providing samples and all support, including huge views addition by hired people and bots for youtube channels. This source told that Apple guy who is his contact had been very proud about numbers of fake views that Apple can provide now to partners.

More benchmarks

As expected we see Puget benchmarks that Apple asked all reviewers to use.

M1 notebooks got first bad for video editing Apple screens

To show energy efficiency Apple changed backlight so it gets more of original uncovered leds blue peak.

This shifted white point, bad for editing.

Small fun thing from inside of Apple, from dev

One of marketing guys proudly told (in small private Zoom conf) that they managed to force all their related bloggers and sites to write about M1 only as 8 core CPU (as first 1-2 mentions and important places), not like 4 + 4 weak cores CPU.

This is one out of eight important points that they checked before any publication. Breaking this points and insisting to not follow them means that Apple stopped including you into privileged list who get early hardware and access to info, few top sites could also loose marketing Apple budgets.

One other point of this eight I know is mentioning of x86 compatibility, publication must never mention any serious issues, must not have any part of problem running full x86 Windows and must be very fuzzy here.

Howdy, Stranger!
