Hi. If I use an eGPU on a 2019 iMac, can I set the mac to use the GPU processing power from both cards at the same time? For one output...
I'm considering buying an iMac, and would want to use a preferred GPU in an external case, and would preferably then use both GPUs.
iMac Line (2012 and Later)
Generally, speaking no. It’s possible to use both, but few, if any, apps are written/configured to use both. What apps are you hoping will use both GPU’s?
Please contact the developer of the app for more support information with regard to you game being written to use both GPU’s.
There are some good comparisons on YouTube that show various frame rates and detail/resolution settings etc. Just do a little research and due diligence and you should find some good GPU’s to use for gaming.
I hope this helps.
Right. Thank you Jeff.
I'm considering an upgrade to and iMac to revisit my teens by getting into Baldur's Gate 3. The GPU that comes with the model I'm looking at isn't that great (a Radeon Pro 570X 4GB) whereas a different video card that's about the same price-value (the Radeon RX580) is much better. Both are AMD, it'd be great if they could both be put to the same app...
