External USB3 Video cards (HDMI)

I assume the CPU of my device would be a possible bottle neck?

And those are?

If the external device did not have its own chip the CPU would have to handle rendering.

Which CPU? Mine from signature does and yours is?

CPU is listed in post:
Cherry Trail T3 Z8300

Those are useful for adding monitors but aren't going to speed up your rendering any.

Thank you for reply.
But is there any device to help with "off unit" processing for render/preview via Cat5 or USB2/3?

Define "off unit processing"

@SethA I don't think egpu via cat5 or usb is possible. I've heard talk of Vegas recognizing a Razor-x via Thunderbolt3 (if you get the configuration exactly right) but the unit + high end video board costs pretty close to that of a compete laptop with integrated video which might yield better performance anyway.

Open Studio
Options -> Preferences -> Display settings / Device
has a dropdown menu.

One of the few items listed is black magic Design,
An amazon search reveals higher end video cards (PCIe)
This one is Thunderbolt:

I'm trying to accomplish something near the same, but as USB just wondering if anyone uses/knows of "off unit/pc" rendering devices? IE: USB device that has some (even if small) processing power on its own, on the device that would/could reduce demands on my mini pc.
Thanks!

Latency and bandwidth is going to kill the performance so the only external GPUs I've seen are Thunderbolt or a proprietary faster connection.

Give up the whole idea and buy a Surface if you value portability that much. Otherwise buy a real machine. Laptops almost qualify in some cases.

I looked into the external GPU approach to do something like what you are describing (keep the laptop portable and connect to powerful GPU when needed). However, you really need a laptop designed for this from the outset with enough Thunderbolt lanes to not choke the GPU for bandwidth. USB 3 and HDMI are a non-starter for preview acceleration- the bandwidth isn't there and the lag between sending data to the GPU and then to the screen make latency unworkable.

Even for Razer and Dell laptops designed for eGPUs, you lose performance vs a desktop system. Price for the enclosure and GPU is high. I ended up with a Dell XPS 15 that's compact but has a reasonable built-in GPU (GTX 1050). You can find this and other laptops in its class that Vegas will edit happily on.

The Azulle Access Plus mentioned by the OP looks like a media playback device designed around Windows 10 vs. Android which I cannot image is truly powerful enough to do any real editing on. On the road I use a gaming laptop with 6-core I7-9750h & dedicated 2060 GPU & just use Windows 10 or Chromecast to share the display over WiFi to a SmartTV or android, etc. media playback device...

I have a $999 Walmart Evoo 17 gaming laptop with I7-9750H CPU, 2060 GPU, (2) M.2 bays & (1) SSD bay for editing video on the go, but it has a short battery life... For days with long meetings, I sometimes use a small MS Surface with touch screen, TB3, etc. but I don't like editing video on it. I have to connect too many external devices to make it useful whereas the gaming laptop only needs a power cord...
