Testing the Radeon RX 580 4GB hardware encoding/decoding in Mac OS 10.14.5 beta 2.
The tests were done in FCPX version 10.4.6, using the 4k video file TCL Supercars 4k Demo.mp4 HEVC size 1.33 GB, also used VideoProc, HWMonitorSMC2 and Intel Power Gadget. I renamed my DGPU as Radeon Pro 580.
The picture 1 shows which GPU is used and loading.
The pictures 2 & 3 shows the time need it for exporting.
Best exporting time is market in red.
Test 1: DGPU RX 580 enabled, IGPU disabled, SMBIOS iMacPro 1,1.
HEVC -> H264 : 4:01 pictures 1&2
H264 -> HEVC : 3:09 picture 3

If want to verify export H264 performance on FCPX, use video clips more than 60 minutes for H264 export test. result will be differnce, AMD VCE should faster than IGPU + DGPU.
