The new 27-inch iMac is here, although you would be forgiven for thinking otherwise. Apple has left the design of its 5K iMac unchanged, but it has overhauled the internals with 10th Gen Intel Core processors and AMD Navi GPUs. The 21.5-inch iMac and iMac Pro have also been upgraded, albeit on a much smaller scale.

I'd like to see the gaming performances of the model with Radeon Pro 5700 XT with 16GB of RAM.
