Keywords

💡Multim monitor setup

A multim monitor setup refers to the configuration of using multiple external displays connected to a single computer system. In the video, the speaker tests the performance impact of connecting various combinations of external monitors to different Mac devices. For example, they connect up to seven displays simultaneously to a MacBook Pro M3 Max using Thunderbolt and DisplayLink technology. The multim monitor setup allows for increased screen real estate and productivity but may impact system performance depending on the hardware capabilities.

💡External displays

External displays are separate monitor screens that can be connected to a computer or laptop to extend or mirror the desktop environment. The video mentions using various external displays, including two LG 27-inch 4K monitors, a 34-inch 144Hz curved gaming monitor, two portable 120Hz displays, and a glossy 144Hz monitor. Connecting multiple external displays to a Mac device is a key aspect of the multim monitor setup being tested in the video.

💡Performance impact

Performance impact refers to the effect that a particular configuration or workload has on the overall system performance. In the context of the video, the speaker is testing the impact of connecting multiple external displays on the performance of different Mac devices. They run CPU, GPU, and memory-intensive tests to measure any changes in execution times or resource usage when external displays are connected. The goal is to understand the trade-offs between having a multim monitor setup and maintaining optimal system performance.

💡CPU performance

CPU (Central Processing Unit) performance refers to the computational capabilities of the processor in handling intensive tasks. The video includes a CPU-intensive test that generates the Mandelbrot fractal sequence to measure any impact on CPU performance when external displays are connected. For example, on the M3 MacBook Air, the CPU test took 4 minutes and 28 seconds with multiple displays connected, compared to 58.6 seconds without external displays, indicating a significant performance impact on the CPU.

💡GPU performance

GPU (Graphics Processing Unit) performance refers to the graphics rendering capabilities of the system, particularly important for tasks like video processing and gaming. The video tests GPU performance by running the Whisper project for audio transcription, which is a GPU-demanding task. For instance, on the M3 Max MacBook Pro, the GPU test took 3 minutes and 26 seconds with multiple displays connected, compared to 48.5 seconds without external displays, showing a substantial impact on GPU performance.

💡Memory performance

Memory performance relates to the efficiency of the system's RAM (Random Access Memory) in handling memory-intensive tasks. The video includes a merge sort algorithm test to measure memory performance. On the M3 MacBook Air, the memory test took 1 minute and 30 seconds with multiple displays connected, compared to 34.4 seconds without external displays, indicating a significant impact on memory performance.

💡Thunderbolt

Thunderbolt is a hardware interface developed by Intel and adopted by Apple for high-speed data transfer and display connectivity. In the video, the speaker connects external displays to Mac devices using Thunderbolt cables and ports.

Transcripts

today I'm diving deep into the latest

MacBook lineup testing their limits with

external displays and their impact on

performance I got MacBook Pros M3 Max M2

Max M3 M3 Pro and a MacBook Air with an

M2 Chip and all these have different

external display support according to

official Apple documentation I'm testing

this out with two LG 27in 4K displays

set up vertically next to me code reads

beautifully when it's a vertical screen

look how much code I can fit in a jlink

34 in 144hz curved gaming monitor two

portable displays by m Duo each with 120

HZ refresh rate and a shiny glossy do

monitor used to be called Eve now it's

called do that one's 144 HZ as well

suddenly it's really warm in here I

don't know

why beginning with the basics I'm

unplugging two monitors to focus solely

on the laptop's internal display for

initial tests the built-in screen is

much nicer looking by by the way I'm

allowed to have opinions

okay we don't sit around just with one

test open one Benchmark or one IDE this

is why we have multiple monitors in the

first place I'm going to start out with

15 tabs open with chrome couple of

instances of Visual Studio code for

those of you that are developers I'll

make the code available those of you

that are not developers suffice to say

that one of these pieces of code is

going to run an intensive test that

generates the manle BR sequence that's

the fractal patterns in numeric format

and that's going to be a CPU heavy task

another one is a GPU demanding whisper

project for audio transcription and

finally there's a memory heavy merge

sort algorithm that one uses a lot of

memory we'll see how all these get

affected as the tests go on now running

these the 64 GB MacBook Pro is using

14.4 GB of RAM showing no swap or

compression and the Windows server is

consuming 370 megabytes Windows Server

this is a Mac what the heck is Windows

doing on it well despite the naming

similarities Windows Server Windows

server is a process on Macs that manages

your open UI Windows makes sense right

and when you add more monitors Windows

Server should use more memory we're

going to test that out I started by

timing the CPU intensive mandal Brad

Python program without external monitors

this clocks in at 25.8 seconds next I

ran whisper that's the GPU heavy task I

might just interchange these terms going

forward this one's processing a video

file which is one of my videos and it

took 51.6 seconds and finally I tried

using different numbers of integers to

do the merge sort I tried 10 million uh

that one uses 500 megabytes of RAM and

that completed in 32 seconds these

initial tests establish our Baseline for

CPU GPU and memory performance and offer

a clear comparison point for the impact

of additional displays now let's plug

the monitors back in I connected

monitors using Thunderbolt cables to two

Hobs linking two displays on each side

the setup includes playing a few YouTube

videos part of my usual Chrome Home tab

collection and some coding workspaces

I'd say for an average developer this is

probably um on the lighter side of load

now currently Windows Server RAM usage

has risen to 1.17 GB with overall memory

at 17.1 GB no swap or compression

initial CPU and GPU tests showed slight

variation within the margin of error

suggesting minimal impact from the

connected displays despite what I

expected the GPU is operating around 80%

utilization and it didn't suffer

significantly from the multim monitor

setup but this is a really powerful

machine and we're still within the

bounds of Apple's documentation so for

now we're okay all right I've changed

things around just a little bit here for

the two side displays this one and this

one I've actually set the resolution

higher to the maximum possible that it

can do I don't normally use my monitors

at such high resolution because well

getting old it's hard to see stuff and

while I'm doing this I'm monitoring the

memory usage by Windows Server the

memory usage overall and the GPU history

I am seeing a little bit of variance

there but in general it's going down

after that test we did also for these

monitors up here I started playing 8K

video uh for this one right here and

this one right here I'm actually also

scaling those to the highest possible

resolution both of them and I'm not

seeing a degradation in the GPU in the

usability of the system or the amount of

memory being used but I still think it's

worth running all those tests again with

these new settings just to make sure so

it looks like everything took a little

bit of a hit but that's just it it was

only a little bit of a hit that's

probably not even worth talking about

but I'm going to share it anyway cuz

that's why you're watching this video

our GPU test is now down to 52.5 seconds

our CPU test is down almost a full 2

seconds to 30 seconds and our memory

test is down to 35.3 seconds hm so

something is happening before we move on

to our next computer I just had to do it

I hooked up all these monitors all six

of them to one MacBook Pro Pro making a

total of seven displays from this

MacBook and the way I did it was of

course using a technology called display

link now this setup required some

rearranging due to a peculiar issue with

monitor rotation settings one of my LG

monitors that was vertical couldn't

rotate to 90° unlike the other of the

same exact model also one monitor

previously recognized as an LG monitor

is now identified as an Apple xdr

display these anomalies suggest possible

display Link in your with monitor

management which adds an unexpected

layer of configuring a multim monitor

setup hopefully only a onetime thing for

each machine under normal circumstances

I don't have this problem at all when I

only have one external monitor hook toop

or two I wanted to add an iPad to bring

my display count to eight from the

comments I've seen some of you use iPads

in side card mode and this actually

raised the temperature to 70° from the

usual 40° now I do have all these other

monitors spinning all the same time so

it's not just Scar the fans which were

previously off are now steady at around

14400 RPM due to the added heat from

driving all the monitors and the chassis

warms to

36° it's manageable for most tasks

though but this might pose some

challenges for intensive activities like

game development I recently did an

intense video with unity which I'll link

down below too with all displays active

Windows server memory usage slightly

increased and overall memory consumption

Rose to 23/2 GB performance tests showed

minor slowdowns with the CPU and GPU

test slightly impacted this starts to

reveal some of the trade-offs of a

multim monitor setup all right now I'm

resetting everything to Baseline by

disconnecting everything now it just

looks crazy in here cuz there's only one

monitor active next machine this is the

M3 Max magma Pro I'm only expecting

better things at this point I ran

whisper in 52.2 seconds and mandal BR

showed a significant Improvement at 17.6

seconds the memory test completed in

29.9 seconds so without monitors

connected Windows server is already at 2

GB of RAM the system's total memory

usage is higher than on the M2 Max

starting at 24 GB including some swap

usage and I wouldn't put too much weight

on how much memory is being used on the

system this increased memory footprint

even before connecting any monitors kind

of shows Mac os's Dynamic Resource

Management so you'll see different

numbers and different levels of memory

and you'll be scratching your head

wondering what's going on here why is my

16 GB machine using 15 gbt of RAM and

I'm not even running anything well it's

Mac OS you'll see this time and time

again and it's nothing to be afraid of

not everything came back on to life uh

those two are not working I got to

figure out why I swear I'm losing it

this is a new machine I did not install

display link on this and therefore we

don't get all those monitors we only get

four now while messing around with this

I found something interesting here in

this drop- down menu for adding my iPad

as an external display I noticed options

for other devices including two Apple

TVs and several MacBooks that I'm

testing testing that are in this office

too can I use these as additional

monitors this MacBook Air

here matters all that

but all the sound from all the videos

are coming to here I guess I always knew

you can mirror to an Apple TV but I had

no idea you can mirror or extend your

screen to another laptop this MacBook

Air is now an extension of the set of

screens for the MacBook Pro I mean there

is a significant lag here don't get me

wrong but if you really needed to do

this

I guess you could that lag is just nasty

that was interesting for the M3 Max The

Whisper test completed in 51.7 seconds

3500 RPM for the fan right

now it's the loudest MacBook I've ever

owned and it's proud of

it memory test took longer at 31.7

seconds and the cpu's manle BR test

slowed down to 22.4 seconds surprisingly

Windows server memory usage remains

stable not what I expected the main

resource consumers here were Google

Chrome Helper processes and this might

have something to do with running 2 8K

videos simultaneously I got to get these

other monitors on here I'm using display

link for extra monitors again I didn't

have it installed in this one so I need

to install the drivers and give display

link all the permissions and sign my

life away and after installation I wait

to see if the displays just light up

boom look at that they just pop on after

connecting the new monitors the screen

layout automatically changes which is

annoying and it requires me to

reorganize the setup to my original

configuration this is not so bad with

two or three monitors but it's pretty

bad now surprisingly the GPU test

finished in 48.5 seconds faster than

before however the memory test slowed

down to 32 seconds and the CPU slightly

slowed down to 23 seconds presenting a

mixed effect on performance which is

unusual onto our next machine this is

the M3 Pro and it's supposed to handle

less screens than the big boys that we

just tested so let's see what Happ

happens when I plug him in whisper at

55.3 seconds mandle broad at 35 seconds

and memory test at 36.9 seconds

definitely a clear performance drop here

looking at the Windows Server process we

got 571 mbes of Ram with a total usage

at 9.8 GB out of the 18 available

significantly lower than the usage of

other devices and I've said this before

that's how Mac OS manages memory it's

not like all of a sudden Google Chrome

decides to use more memory because it

knows it's on M3 Max machine with more

memory available able no it's Mac OS and

it's actually perfectly normal all right

let's plug in this side first this is a

thunderbolt dock that has these two

monitors connected to it and I should

see them both pop up indeed they did

let's do one more just attempt some fate

this is the HDMI output to this monitor

over here nothing happens over there so

I guess we're done connecting the

monitors immediately increase memory

usage to 11 GB with Windows Server

consuming 757 MB this demonstrates an

immediate memory impact by adding

displays the temperature is a little bit

higher now but that's to be expected

after doing the CPU test which has

slowed down quite a lot here we've got a

big drop in performance down to 41.1

seconds just from standard two display

setup nothing crazy now while the

machine remained responsive which is

good the GPU slowed down to 1 minute and

the memory test slowed down to 40

seconds pretty typical usage conditions

but we do have a performance dip here

after switching to a display link Hub

two additional monitor instantly popped

on and this raised the memory to 13.8 GB

and Windows server to 1.24 GB this setup

tacks the GPU and I anticipated this

that 8K duck is so beautiful I can see

every feather and performance test then

showed a dip memory test took 41 1/2

seconds GPU test 1 minute and 6 seconds

and the CPU test was the most impacted

slowed down to 46.7 seconds this was our

GPU test right here sound effects they

make everything great all right who's

next the nonpr magbook pro it doesn't

even have a thunderbolt hole on this

side testing the M3 Macbook Pro not the

pro or the max just the M3 this one

reveals some slowdowns however its

performance was decent the memory test

completed in 30 seconds Manel BR in 44.4

seconds and Whisper GPU test in 1 minute

and 8 seconds starting from a slight

disadvantage of having just 8 GB of RAM

the outcome kind of aligns with

expectations for this Hardware

configuration since I can't plug this on

this side there's no holes let's bring

this on this side there we go that's not

true there is an HDMI output there I

could have used that but let's see how

Thunderbolt does one and that's it so

how we get one I tell you what though

this machine is pretty spiffy with just

one monitor plugged into it let's get an

8K video going maxing out the native

displays on this non-pro MacBook Pro

slightly extended memory test times to

30.9 seconds with a whisper GPU test at

1 minute and 10 seconds and the CPU at

47 seconds I'd say not bad despite being

8 GB model it used 6.7 GB of RAM and

just over 3 GB of swap here we see Mac

os's Dynamic RAM management based on

availability dipping into that swap a

lot of people are complaining about that

but in reality you probably won't even

notice it you'll probably get rid of

that machine or sell it before you even

experience any problems with that SSD

another story for another time with

display link memory pressure appeared in

influencing performance the memory test

is at 31 seconds GPU at 1 minute and 12

seconds and CPU at 48 1/2 seconds so

we're pushing this machine much harder

now and it's starting to show but not

terrible there's one more machine left

and I'm expecting the same results as

this one this is the MacBook Air M2

kicking off the MacBook Air this being a

24 GB Ram version and straight off the

bat it's gobbling up 16 GB again don't

jump to conclusions if you skip to this

section Mac OS loves to sprawl out when

it's got room this isn't a sign that

it's overloaded just Mac OS being Mac OS

making sure that it's using what's

available remember folks 8 GB of RAM on

a Mac is like 16 GB on

Windows leave your comments down below

all right kidding kidding okay but if

you want me to do a breakdown on how

memory works and how it's different on a

Mac or Windows let me know in the

comments down below too here Windows

service chilling at 689 mbes diving into

the test and you'll see 35 seconds from

memory and mandle BR CPU test outpacing

the M3 MacBook Pro at just 53 seconds

and the GPU is starting pretty strong at

a minute and 6 seconds it goes to show

you again that the air is not just about

light work it can do some serious damage

I'm running the CPU test and it's really

quiet in here and I'm wondering is this

test even running I had to do a double

take the temperatures are at 108° but

there's no noise cuz there's no fan so

I'm expecting this test to take a little

bit longer and of course the CPU test

suffered the most because of those

temperatures if I ran this more than

once in a row it would really

drastically slow down but the CPU is at

58.6 seconds here not horribly worse but

a little worse the GPU is actually about

the same 1 minute and 7 seconds and the

memory test is faster faster 34.4

seconds total now that the M3 MacBook

airs were announced those chips are

supposed to be hotter so we'll see how

that affects performance stay tuned for

that on this channel Channel I've got a

surprise for you this MacBook Air is now

connected to 1 2 3 4 displays so that's

a total of five including the internal

One display link helped out here let's

take a look at Windows Server 880 megab

of ram 15.3 GB of memory used so we're

not really doing much here the machine

is still perfectly usable like it was

before now it's important to realize

that fan can really do wonders

especially when dealing with some really

heavy workloads like I've been throwing

a this thing and uh the result kind of

shows let me show you now we're waiting

for the GPU results but the CPU timing

shocked me 4 minutes and 28 seconds ouch

it seems like this collection of

monitors display link and iPad

significantly strains the CPU that's a

shocker but because there is no active

Cooling in this machine this is what

happens the memory test also extended to

1 minute and 30 seconds wow almost three

times longer than before this is a

substantial impact on performance

clearly Having side cut open having

display link playing is having a really

huge adverse effect our GPU test just

finished and we're at 3 minutes and 26

seconds for the GPU result the slowest

I've seen so far addore screens turned

out to be more than just getting more

surface area to do my work it was a real

test of what these machines can handle

under the hood everyone's workflow is a

little different so hopefully you can

find a good balance between having

enough real estate and performance for

your own needs I want to extend my thank
