Computer Upgrade For ThinkOrSwim

Curious to hear people's experience with new Apple M1 Chip performance on ThinkorSwim despite it having to use Rosetta 2.

I am on the fencepost of buying a M1 Macbook Air for ThinkorSwim so want to make sure it performs well.

Thinking of getting base model Macbook Air + 16gb ram.

Thanks in advance!

@BenTen anyone you may know who has experience with ThinkorSwim on M1 Air or MBP?

@corello Here are the TOS computer requirements: https://platform.thinkorswim.com/platform/index.html#!/system-requirements

You only need to meet the TOS requirements listed above. Anything beyond that will not provide any great benefit given that most operations occur on the TOS servers.

@corello I use Last year Intel Version MBP 16' Specs below, as well as a Custom Build Dual Xeon, Server Board with 256GB RAM and Dual x M4000 (2 x 8GB) GPU.

That said, what I have found out is, TOS is and will continue to use Java AWT for GUI, Until it is completely re-written. What this means is, We can only use single Core, no matter how many core you have in the system. Modern OS (Windows/macOS and even Linux) are designed to select the best CPU core to run any application, so Multi core helps.

What is best for TOS is not more Cores, but more GHz per core. I would pick a CPU that can scale up to 5Ghz even if it only 4 Core over CPU that can only do 3.8 Ghz 10Core. I would honestly consider building a PC with AMD CPU. GPU isn't critical either, since all TOS do is a 2D Graphics. I haven't tried a M1 Mac yet, but I might soon, will let you know when I have more info.

Surprisingly, although I have two relatively powerful trading workstations I do most of my work and trading on a paltry 5 year old Dell Inspiron i3 upgraded to Windows 10 with 8G RAM and a 500G SDD, with 100mbs broadband... I can run one or two instances of TOS with multiple chart panels open and my fan NEVER runs... It also has Firefox and Google Chrome running 24/7 with 6 to 8 open tabs each... Waiting on the TOS servers is my only bottleneck, not my PC's or broadband... The only downside is that the laptop has lower graphics capabilities than I'd like but I manage just fine...

I'm an IT Consultant and I perform cleanup maintenance every weekend... I do not recommend using any Norton or McAfee products as they diminish performance more than they provide protection... I run the default Windows Security that comes with Windows 10 and am very diligent at being careful where I point my web browsers... I clean up more PC's that run the aforementioned commercial packages, by far... When I prep a new PC's for customers I remove the pre-installed trial security packages and insure that Windows Security has taken over protection... My actual trading workstations only run TOS...
 
Ah, I remember those Windows days of constant clean up and maintenance.

I think the high end x86 MBPros have GPU cooling issues. CPU is not taxed much with ToS but once the GPU starts getting utilized, fans get excited. I can hide ToS and hear alerts, meaning runs in the background, and fans calm down.

I don't perform cleanups out of necessity, it's just force of habit - like changing underwear and brushing my teeth... But you'd be amazed at how some of my customers can muck up a computer without even trying... They never learn, no mater how much I reiterate things to them, but it keeps me in business...
 
I know this is discussed from time to time, I have not seen any recent discussions. I am going to upgrade my PC and I would like some input from the group as to which computer system you like. The best to run many monitors and trading platforms. THANKS!!
 
I moved your thread here, to see what upgrades other members have done.

I remember back in the day, AMD CPUs would sometimes have compatibility issues with certain apps. Has anyone noticed any compatibility or stability issues when running TOS on a Ryzen computer?

Thinking of going with Ryzen for my next build, but if it's going to cause any issues with a mission critical (for me) app like TOS, then I'll stick with Intel.
 
I found Mobius's comments on PC computer specs needed for running TOS to be succinct and accurate.
This is helpful for anyone thinking of upgrading their computer.

After I upgraded to a current gen Ryzen computer, I saw a lot of improvement in terms of the amount of chart lag while running a bunch of complex indicators simultaneously.
 
What CPU did the old PC have, and which Ryzen processor does the new PC have?
I've made this type of upgrade twice. I don't recall my old machine's cpu but it was a gaming laptop from maybe 2017, and I upgraded to a laptop with a Ryzen 4800U about 1.5 years ago. The difference in chart lag was massive. I then got about four months ago a laptop with a Ryzen 9 series chip (5900HX) and it was a noticeable improvement over the 4800U but perhaps only because I have a lot of concurrently running studies that use the SecondsTillTime functions and others which are huge resource hogs (and I'm running dozens of studies concurrently on a 1min chart which may be more resource intensive than higher time frames, not sure if that is making a difference). For more standard chart setups it's surely overkill having such a powerful gaming laptop. I also found that having 32gb ram helps and a very powerful gpu is probably also helping although I'm less sure about how much difference the gpu is making.
 
I am going to upgrade my PC. Any advice on a great system that will drive multiple monitors/charts etc.?

Thanks.

Keep in mind that Scwab is building a combined platform debuting late 2023 which should be multithreaded.
Like @petergluis, the 4k monitors are game changing. I can have TEN lower charts!
To run the higher res monitors get the best graphics card that you can afford.
Thanks guys!
 
i went middle of the road, not too expensive. some day i will upgrade to something like petergluis mentioned.
i have an i7 lenovo laptop with a USB-C dock , driving 2 tv's , 32" and 48"
my usable resolution is limited by the laptop , 1920 x 1080, which isn't bad, i can read it.
the dock is capable of double that 3840 x 2160

the dock has graphics hardware and gives me an ethernet port.
