Minimum requirements for running Core

I am wondering if anyone has any experience or advice on creating on Core on a computer that doesn't meet the minimum requirements. Specifically how well does it run on an AMD 3200G or 3400G with integrated graphics Vega 8/11 Graphics?

Does anyone have experience running it on a 2017 era 27" iMac with Radeon 575 graphics card (booted into Windows 10, not Mac OS)?

Minimum stated requirements are Nvidia 1050, recommended 1660Ti. At this point with the graphics card shortage everything is very scarce or overpriced. Probably best available is 1650.

Hence I am curious about running this on systems under spec.

Any thoughts from the community greatly appreciated.
