I'm using an iMac Pro base with a 4k monitor connected via eGPU.

The eGPU box is the Akitioo Node, and the GPU is the RX480 4GB.

Lately, even without it, noisy eGPU boxes have become louder,

I watch YouTube from the extended monitor connected to the eGPU, use the power of about 120 watts GPU usage. Even  scroll through the screen in a web browser, about 90% GPU use

(I also benchmarked, but the speed is normal.)

I've been connected to a MacBook Pro 2018 that I'm living with, the same phenomenon.

I have also changed the Thunderbolt cable, but there is no change.

So far the conclusion is

1. iMac Pro is a bit strange = x: MacBook Pro 2018 is in the same situation

2. Thunderbolt3 cable is a strange third party = x: I bought a new genuine by apple.

3.GPU tastes gone = Possible

4. eGPU box tastes gone = possible

5. Is this the Mac OS 10.14 series? Maybe not

I will ask you a question and ask at the same time.

1. In this case, do you suspect the GPU? Or should I suspect an eGPU box?

2, In this case, I can not search  cases yet. It is possible that this is a general problem of MacOS, and I will send a test request to those who use eGPU.
Just watch the YouTube 1080p on the monitor connected to the eGPU, and check the GPU usage in 'Activity Monitor'.

I just turned a regular YouTube on Chrome and it's not like 4k. -;


Thank you.
