I've been looking at the GPU in the 2018 model which is a UHD 630. This is the same chip that was in the prior generation Kabylake CPUs. And according to research the likely chip for the 2019 Mini will still be using the same 630 model. E.g. https://en.wikichip.org/wiki/intel/core_i3/i3-9100 So that begs the question of whether we should skip the 2018 and 2019 models while we wait on upgraded iGPU in the 2020 Mini?
