I've connected my 2K monitor to eGPU directly, and I ran geekbenck4 opencl test in my external display. The score shoud be more than 150k, 130k is too low. (Akitio Node + RX580 4G: 110k, win10 + built-in Vega56: 180k).

The Akitio Node3 only has a 400W PSU, but I don't think this is the problem, because I use my eGPU only for final cut pro instead of gaming. I don't know why this is happening, any advice will be appreciated, thanks!

Run the Unigine Superposition benchmark in Windows instead.

You can get good system performance info there.

Thanks for your reply! Are you suggesting the geekbench4 opencl compute benchmark is not reliable? This eGPU setup is not for gaming, so the OpenCL compute performance is more important than famerate. PS: I've run a Geekbench5 OpenCL benchmark, the score is 59K

Superpostion results are consistent over the last several months.

So you can meaningfully compare your Superposition results with other Vega 56 owners. 

(Not going to comment on other benchmarks 😂)

You can also run the Luxmark render benchmark to test Mac Open CL performance.

Thanks, I should be very careful because the 400W PSU cannot keep vega56 running at full load
