I was originally going to purchase the Radeon VII for my eGPU set up but after seeing the RX Vega 64 Liquid Cooled + Razer Core X Chroma build by @itsage I decided that was sufficient GPU power for my needs and furthermore I preferred the design and low noise of the liquid cooled card.

I found a used RX Vega 64 Liquid Cooled for a decent price 450 euros and it was in perfect condition. During my first tests the Unigine benchmarks were very unstable and a couple of Steam games caused the GPU to become noisy. @itsage pointed out that the default VBIOS was probably overclocked by the previous owner so I switched to the energy saving VBIOS. The result was successful, all the gaming, 3D and pro apps worked without a problem. The energy saving BIOS also makes the GPU run super quiet with very little performance penalty.

Other observations.

i. 10 bit colour support, flawless.
ii. Audio over HDMI to my 4K HDR display, flawless.
iii. Plug and play all the way, flawless, superb.
iv. 8K video scrubbing in Da Vinci Resolve 16b, great. I used the 8K sample HELIUM 8K from Red's site for the test.
v. The free version of Resolve appears to render out using only the CPU though. Maybe the full version renders on GPU?
vi. Image and video in Creative Cloud apps, super fast viewport navigation and resizing. This was the most important reason I needed an eGPU as this operations cause the MacBook Pro to throttle and choke.
vii. I put the Razer Core X in vertical position on the floor under my desk. This allows me to use a short Thunderbolt 3 cable to reach the MacBook Pro on my desk. It also makes the USB ports very accessible.
viii. This card is super quiet most of the time and under load it makes a pleasant whirring sound.
ix. Perfect sleep performance. The card goes to sleep and wakes flawlessly.
x. Tried Rise of the Tomb Raider. Same performance as the 1080 Ti but that's not great. It's a very badly ported title that randomly jerks and freezes even though the GPU is not overheating. 

I'm super pleased.

@craftsman,
nice build. The "vertical position" is intriguing. Can you tell us more about your Samsung monitor? It has 6400x3600 resolution?!

Samsung 4K display. It's not really 6400x3600 resolution. The System Profiler has a bug that misreports the screen resolution. The Display Preferences correctly shows that it is 4K...

@craftsman nice setup! How are the vibrations when standing the enclosure vertical? Does it gets transferred to the floor or desk? Might want to do the same.

For Resolve, if you are doing basic editing, the GPU won't load up. Only once you start having correction nodes, grading, fusion, etc and resolve will really chew through the GPU.

I think it's a shame to have a LC Vega 64 but use the power saving vbios. Search for the original Vega 64 LC vbios on techpowerup,

https://www.techpowerup.com/vgabios/195319/amd-rxvega64-8176-170811

boot using the v64 power saving bios in windows, flick switch to normal bios, and flash, and should be good to go. If it still crashes it might not be an issue with the bios (very few LC owners mod their bios) and could be hardware problems - check your temps and compare with other v64 LC owners. If coolant is leaking/evaporating have to address asap.

No vibrations at all, even under full load.

When you apply nodes and LUTs to video there is brief whirring up of the fans. Same in Creative Cloud apps. It's a pleasant sound anyway, kinda sci fi sounding like when Robocop turns his head.

I'll install the card in my PC and restore the VBIOS there but otherwise I'm not seeing a performance loss in energy saving mode. Maybe 1-2% max.

Surprise! I discovered that macOS was running my display at 6400x3600 but it was downscaled to fit. By choosing 'Default for this display' I now have the correct resolution, except that I have to live with slightly smaller fonts.  There's a small improvement in performance and grading in DaVinci Resolve is real time.

@craftsman Nice build! I wanted to ask if you have noticed the enclosure PSU fan noise during sleep. I hear it when the Razer Core X Chroma is asleep while connected to a TB3 host (MacBook Pro, Blade Stealth, and Mac Pro).

Perfect sleep. I leave the setup plugged in all night and it doesn't wake until I hit the keyboard in the morning.

Correction. Today I used to eGPU for work with hard drives also attached to the Chroma's ports. At the end of the day I put the machine to sleep but the PSU fans continued to gently spin. It appears if you use the system very thoroughly then the PSU doesn't fully sleep. It's easy to tolerate but I decided to disconnect the eGPU before sleep.

Have you've managed to find a way around this? Or is it just resolved by unplugging it?

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.
