I have a Mac Pro with two LG 5k displays. I am thinking having two Radeon Pro 580x MPX modules to drive two displays, so the performance might be better. Is it possible to do that?
Mac Pro, macOS 10.15
Save your money, there is no need to do that.
The load on a graphics card to show the data in its RAM on a display uses some hot fast logic, but is not especially taxing, and these cards can already drive up to to SIX 4K displays without slowing down one bit.
The reason some users want more GPU power has to do with the OTHER side of a graphics card, the GPU computation --- when the CPU off-loads 3D drawing, shading, texturing, and similar operations to the substantial parallel numeric capability of a GPU compute engine.
If you are not doing professional cinema production or 3D modeling, there is no need for multiple GPUs. And if you ARE doing those things, you want the card with DUAL, Linked GPUs to get the best GPU compute power from it.
Maybe.
If you are trying to run a single application faster then NO (unless the app supports multiple GPUs).
If you need to run two graphically demanding apps at once then sure, start each app from a monitor connected to a different GPU.
Can I install two Radeon Pro 580x MPX modules in a Mac Pro for better graphic performance?
