change the graphics card in my iMac 27 (Mid-2017)
Hello! Can I replace my graphics card Radeon Pro 575 4GB with a more powerfulRadeon Pro 580 8GB ? If so, how can I do this? I will be grateful for the instruction.
Sadly you can't swap out the GPU unlike the older 2011 models and older. From 2012 'Thin Series' use a soldered down GPU chip on the main logic board. Here is the teardown for the slightly older system for reference: iMac Intel 27" Retina 5K Display Teardown Jump down to Step8 for an over view of the chips on the logic board. Apple only did a slight upgrade to this system for the 2017 model.
