Seeking eGPU for Mac & Dell for dual screen (int + ext) use

Hi

I <hope> I've read around enough of this forum and other eGPU related sites by now that this question doesn't seem like I haven't done my homework.
Here is my intention...

At work I have a Dell XPS 15 9570 (i7, 1050maxQ, 64GB Ram, 512GB SSD, TB3 x 1)
and two Mac Air 2019 (i5, 8GB Ram, 512GB SSD, TB3 x 2)
plus a DP monitor

My main activity is editing and colour grading in Resolve 16 Pro on the Dell.
BUT I also teach some minions video editing and they will use the Mac Airs for light tasks.
Some form of USB or TB3 passthrough is essential as we will have the media drives connected too (minimal overhead in real terms).

The workloads are very VRAM hungry so I want to go with the Radeon VII 16GB but if that's a real no-go 5700XT 8GB is not off the cards.
Given the lack of availability of eGPUS where I live (Tokyo - go figure!), my options are limited to two that my workplace would potentially buy me from Amazon.
The Razer Core X Chroma and the Akitio Node Pro. Only the Razer officially supports Radeon VII and the "builds" section suggests it's a good option for both PC and Mac.

Thing is when editing we need dual screen functionality - as in, Resolve windows will be spread across the laptop screen AND an external DP monitor.
While after much research I am fairly confident that the Razer + Radeon VII will work on both Dell and Mac, I'm most keen to know (1) if I can use the laptop screen and DP monitor as I intend and (2) would the Akitio Node Pro work and if so in this way too?

I had thought about the Mantiz Venus but it seems it wouldn't work in (1) - also, cannot find it in Japan.
I had also thought about the Netstor HT23 (whatever version has the additional TB3 port) - but also, cannot find it in Japan. 

Thank you for any advice you can offer! Especially if you have tried any combination of the above.
(If you happen to work for Black Magic please release a Vega64/Radeon VII version that's compatible with PC and not more expensive than a new computer!)

Yes, a new Vega 64 Blackmagic would be best suited to fill this niche you are looking for. 😁

But running two external displays from the eGPU will be much easier than trying to use the Dell or MacBooks displays.

Here in the US, I would choose a temporary solution of a PowerColor Gaming Station ($250 US price) housing a Vega 56 - making sure it has Samsung HDM2 vram ($300 US price). 

You could use the Gaming Station Ethernet port to connect to media files on a network accessible storage device. 

(Unfortunately, the USB and network ports on the Core X are unreliable)

 

2018 Mac Mini i5 / 6-core 3.0-4.1 Ghz / 32GB / 256GB / Intel UHD 630 / PowerColor Gaming Station / PowerColor dual-fan RX 5700 XT / Mac OS 10.15.6 Catalina / Windows 2004 😏 / Dual LG 27" 4K displays

@mini-i5, thanks for the reply.

Good ideas. Though strange as it sounds the dual monitor set up is a no-go.
Long story but essentially desk space is limited. So is that intended monitor set up not possible?

Alas Ethernet will not be up to the task, it has to be USB3 or TB3. Also the Powercolor isn't available in Japan.
My storage is a Drobo 5D3 (which I have to use via USB3 not TB3 on Windows as Drobo lied about TB3 support in Windows and continue to do so - if the Drobo supported TB3 then the eGPU could be anything).
I heard the network port on the Razer was suspect but didn't realise the USB ports might be as well.
Thanks for the heads up.

If only GPUs had a USB port on them!

Cheers

You’d need to try adding a Caldigit TS3 dock (which has a USB-C port) in-between the Dell 9570 and the Core X

https://egpu.io/forums/thunderbolt-enclosures/success-chaining-caldigit-ts3-plus-dock-egpu-with-three-4k-60hz-displays/

But it will still be very difficult trying to accelerate both an external display and the Dell’s built-in display.

@mini-i5, !!!

I hadn't thought of that, great idea.
Actually that might be the way forward...

Technically the laptop will be driving both displays as it currently does, but the eGPU will be doing the crunching, and I can find something cheaper than the crazy-razer (was that a 90's nu metal band?!). AND this interface can power the laptops too! Sweet.

I'll look into this.

Cheers
