I upgraded to a metal-compatible GPU (Radeon RX 580 Pulse) primarily because Mojave requires it and the clock is ticking on High Sierra. Now I'm trying to figure out whether or not to utilize metal or OpenCL for Photoshop, Camera Raw and photo stacking.

I found comments on online forums saying that OpenCL performs better on a Mac than Metal. There was speculation (wishing) that with updates over time Metal would perform better, but that time has not yet come.

Anyone have experience to share regarding Metal vs. OpenCL with Mojave on cMP 5,1?

High Sierra (active)
Vanilla Mojave (installed on separate HDD partition) and soon to be clean-installed with applications on an NVME SSD.
Boot Rom 144...
Photoshop CC
