eGPU with Mac mini 2018
I am confused whether I should connect eGPU with Mac mini or with monitor directly! Thunderbolt 3 monitor is expensive, and usb-c port (without thunderbolt 3) has smaller bandwidth (does eGPU work only by thunder old 3? Or it works too with hdmi/DisplayPort?). Then, except black magic and sonnet, does the Razer one also support? Thanks.
I disregard iMac due to its old-looking design.
