Waiting for the 2019 MBP [Merged]

Power consumption of 120-144 hz displays is in the article You posted here.

It doesn’t give a figure explicitly one way or the other, just notes there’s a minimal power consumption increase going from 60 to 120Hz, but a big penalty for going to 144Hz because it kicks the GPU into a higher power mode in order to provide the extra frames being called for

Due to True Tone, the displays of the new iPhone constantly show white light of the correct intensity and temperature. This allows the image to always look more natural, helps reduce eye strain and makes reading the text more comfortable. The main thing is not to give up on it not being dismantled in detail.

Why doesn't going from 60 to 120 Hz kick the GPU into a higher power mode?

Why is the high refresh rate such an issue with MacBook? iPad with A-series chip and a smaller battery than Mac already has it, so what's different for getting it in a laptop configuration?

You haven't read properly the article.
There is a link to actual review, and testing done by PCPerspective.

You will not see a difference on a 144 Hz panel by going to lower refresh rate. But you will see a difference in 60 Hz panel by going to higher refresh rate. It still is 25W Display, way too high power consumption for MBP.

Because in iPad the High refresh rate kicks in ONLY when you scroll or motion picture(video, game, etc). Otherwise it Immediately throttles to 30Hz, to save power.

For MBP the problem is not the refresh rate, but when you do anything performance related. 80W of Power from PSU are consumed just by GPU, and CPU. There are 7W left for Mobo, RAM, SSD, display, battery, etc. All of current 144/120Hz displays consume between 20 and 40W alone. There is not enough power in the PSU for Apple to use it for for example gaming, etc.

You could only use while scrolling through web pages, or watching a movie(which would be pointless because most movies are 24 or 48 Hz, anyway).

Is it not possible to implement the same way as in iPad pro where high refresh rate intermittently kicks in.. maybe using T2 or a custom chip for lower power consumption.

Also, if most videos are 24 or 48 Hz then what's the use of ProMotion high refresh rate on iPad? Possibly just for smooth scrolling and gaming, so why the tech will not work in Mac? I am not talking about for high refresh rates all the time like in gaming but something on par with iPad

Its because on iPad gaming with ProMotion does not exceed the power threshold, just shortens the battery life massively.

On MacBook Pro running 80W compute hardware, 20W display, and 7-10W RAM, MoBo, Battery, etc would massively exceed 87W power threshold you have from your PSU.

Unless, Apple would allow in this circumstances the hardware to draw the power from the wall and from the battery, but that would be very short lived.

I also chuckled about the idea of using T2 to lower the power consumption of the display, which has nothing to do with it :).

I know the purpose of T2 chip is different right now, I was referring to custom chip for this purpose or integrating it's functionality into T2 or T3 in the future. Since Apple has designed it for iPad which has a large display (though not as big as Mac) with smaller battery, it's possible to extend it for Mac.
I am just trying to figure out how it could be possible to have high refresh rate screens on Mac and looks like biggest power drawing components are CPU (Intel) and GPU for which Apple has alternative chips available from iPad components and if those could be used in conjunction with Intel CPUs on Macs

Power consumption of high refresh rate has nothing to do with internals of the computer, but the display itself. Brightness, refresh rate, circuit designs - all of this has affect on power consumption of the display.

We are talking about 500 nit display that has supposedly to refresh itself 120 times a second. Not 350 nit, or less.

iPad's Display, first of all, is nowhere near as bright as MBPs is, secondly it's PSU/Battery doesn't have to power 50W CPU and 30W GPU, alongside Battery, MoBo, RAM, SSD at the same time, but just 4W SoC.

Will need to modify my wish list based on what the 2018 models checked off...
  • Hex-core Coffee Lake Hex-core Cannon Lake
  • More reliable keyboard
  • 32 GB DDR4 RAM 32 GB DDR4 RAM as standard
  • Increased display resolution
  • Lowered base price
Done.

What display resolution do you need? The 15" has 220dpi, way more than the eye can see from any reasonable distance. 4K makes sense on larger monitors. Certainly my QHD 24" isn't quite crisp, but for a 15" the MBP res is plenty. I have to be uncomfortably close to be able to see pixelation.

As for the keyboard, I guess its a wait and see situation. This is my first butterfly mechanism keyboard, but I'm surprised to find I really like it, and prefer it over my Magic Keyboard at times (aside from the Touch Bar - although I am liking that it will let me fast forward through YouTube ads that you can't skip from the browser). But a week definitely isn't enough to gauge reliability.

Well, I was going to purchase 2018 MBP to replace my 2011 MBP, but after seeing possible problems with T2 and Bridge OS, I guess I will wait another year and hope Apple fixes all these issues.

No worry. The later software update will surely fix it.

I don't have any problems with the T2, but yet I can't help but think its not ready for prime time. Its such an intermittent issue, its hard to completely fault Apple. They're struggling to find the cause, it started with the iMac Pro and they have made some headway but not enough

I know this thread is waiting on the 2019, but with Intel's announcement of re-entering the dGPU market in 2020 (and having hired AMD's lead dGPU guy), could Apple's future dGPU's be with Intel as opposed to AMD?

So I'm late to this...but why did Apple choose to ignore the non-TB 13" MBP this year?
Click to expand...

They didn't ignore it, the coffeelake chips that are available at 15w (which competitors are using) currently only have an Intel 620 iGPU, which is far weaker iGPU than what it currently has.

So they are basically waiting for the right iGPU to be available...maybe we will see the 12" MacBook and 13" MBP updated at the same time around October.
