Dear Sir/Madam I am Reza Teimouri a user of Mac Pro 2019 with AMD Radeon Pro 580X 8 GB graphics card, which I want to upgrade. I am writing to know if it is upgradable or I have to change the card completely? I look forward to hearing from you. Best reg
Mac Pro, macOS 10.15
To upgrade you will need to change the card completely.
(You might be able to install a new card and keep the old, but most applications can't use two different graphics cards in which keeping the old would offer limited benefit).
There is no need to replace the card if all you need is more displays.
"With the default AMD Radeon Pro 580X graphics processor, this Mac Pro supports as many as six 4K displays, two 5K displays, or two 6K Apple Pro Display XDR displays."
