Thunderbolt & Graphics Adapters?

    Ok, so my knowledge on PC hardware and how it functions has clearly waned over the years, so I need some guidance.
    If you have a laptop with, let's say, integrated and an Nvidia GPU in it, and you have DisplayPort/HDMI/etc external ports ... it use to be that with early version of HDMI and DisplayPort those connections could serve a single monitor each. Now I see people using Thunderbolt 3 docks omegle xender and serving out multiple monitors off of a single DisplayPort connection. BUT, I always assumed those had a cheap GPU build in so all the rendering was done inside the dock. The other day, someone said "no, with some of the laptops, you could have 2 external 4k monitors at 120hz off the Thunderbolt 3 dock so you only need to connect 1 cable to the laptop and it all renders off the internal GPU of the laptop so you can still play games and do it all over the one cable to the dock".

    Is that true?? Would that work on a Razer Blade 15 Studio?

    I'm trying to make this thing easier to move around as I game with my kids in one room, but I use it as my work PC in my office too. If I could have this thing down to 2 plugs (power + dock), and still be able to connect my two 4k monitors running at high refresh rate when it's at my desk, that would be amazing.

    Thanks for any clarity you can offer!

    Raser pc for college

    I'm on my way to do an engineering undergraduate thesis project and need a powerful build for vehicle simulations via Solidworks. Will it be enough to have an NVIDIA GeForce RTX 2060 on my Razer Blade 15 (Thunderbolt 3)?

    You might want to think about Quadro series, because you have mentioned the word "powerful"

    Rendering works isn’t done on the dock (unless the dock has its own gpu like Razer core), it’s only mediator to output pictures, rendering is on cpu/gpu inside your laptop. What you need though isn’t DP but thunderbolt output and the thunderbolts dock, but for 2 K monitor 144Hz the bandwidth won’t allow it, only newest DP 2.0 can do that, I think blade laptops still using DP 1.4 and TB3 30gbs bandwidth (dual 4K 144Hz on DP2.0 I believe double the bandwidth) that handle dual 4K @60Hz/ 4K144Hz. Using TB3 dock will limit the dual monitor to 60Hz. So to run dual 4K @144Hz monitor you have to options using two output, usb C thunderbolt and DP or using Razer core with its own gpu DP outputs.
    It’s only my theory since I didn’t run it on real world, only had experience with triple 1440p monitor running through Razer core on gaming but since the gpu (2080) can’t run the game however over 60fps and 2 other monitors was 60Hz, didn’t put attention on high refresh rate.

    I'm headed to do a designing undergrad postulation venture and need an amazing form for vehicle reenactments through Solidworks. Will it be sufficient to have a NVIDIA GeForce RTX 2060 on my Razer Blade 15 (Thunderbolt 3)? Bazoocam
    Much obliged.

    Anyone have any advice or experience using an external GPU? It seems like a lot of the posters here are laptop users and i've been wondering if these GPU docks are worth it.

    Depends on your use cases, if you want to boost your weak gpu on your system and has thunderbolt port, you can add some juice using external gpu, and depends on the enclosure if it has other io ports and your system is an ultrabook like Razer Blade stealth, book 13, MacBook, Dell xps13 that can be charged by its thunderbolt port you can make it one cable solution as docking station and gpu boost unit. Here for example the boost with the Egpu enclosure, Razer Core v2 using Rtx 3070.
    It has io ports to connect pheriperals like keyboard, mice, gamepad, so after using it from work, plug the thunderbolt cable and it transfers to gaming PC (the gpu connected to 27 inch 1440p g sync monitor so you’ll get quite good gaming experience out of it). The thing is with current gpu price maybe it’s hard to set up Egpu setting with reasonable price today.

    I have a 2020 Blade 15 base with a 2060 Max-P and I am wondering if it could support a 1440p (QHD) 144hz external monitor? Or rather, will it be able to maintain the same or similar fps as I experience on the built-in 1080p display? I saw a comment somewhere that switching to a QHD display would significantly slow down the fps.

    Also, is the Thunderbolt3 the best way to attach an external monitor, or the Usb-c, or the hdmi? I've read a lot of different answers and also mixed responses about which 2 of the 3 connect to the dGPU.

    You know your stuff! Could you help me out? @Joikansai

    Of course if you’re displaying higher resolution 1440p you’ll less FPS than 1080p on your internal screen or any other external screen 1080p since 1440p push more pixels and you get better quality, how big it depends the titles and game setting. Personally on external (27inch) monitor I can’t play on 1080p since it looks blurry on bigger display to me, on 15 inch display like on blade 15 it’s fine. For connection you can use all ports available, hdmi, TB3/usb c (using adapter), all connected to nvidia gpu, only the connection way if it’s direct or undirect, and if you have g sync monitor to pull out it you need display port connection which’s I think on your model is on left side usb C, not quite sure since I don’t have that unit, it’s different depends on model. So if g sync doesn’t matter to you, get hdmi cable and connect it to your external monitor and see if it can use maximal resolution and refresh rate, I’d personally spare thunderbolt for other accessories like ssd etc for its fast speed.

    Thank you for the response, @Joikansai!
    I agree that on a bigger 1080p display the image looks blurry, and so I am trying to keep a similar PPI as the 140 PPI that the built-in display has. A 27-inch 1440p display has a 108 PPI which would be great, however, not if the fps drops significantly. Thank you for the recommendations on the ports to use also! G-sync is a must.

    Would you happen to know how significant the drop in fps is? Let's say I get 120 fps on my built-in display playing a game. If I played that same game (on the same video settings) on a 27inch 1440p monitor, would the fps still be near 100? Or would it significantly drop down to say maybe 60 fps?

    Thanks again!
