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.
Model A1419 / EMC 3070 / Mid 2017 / 3.4, 3.5 or 3.8 GHz Core i5 or 4.2 GHz Core i7 Kaby Lake Processor (ID iMac18,3) / Retina 5K display. Refer to the older iMac Intel 27" Retina 5K Display (Late 2014 & 2015) guides as the system is very similar.
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.
