Testing Overview
You can adjust the UMA size for graphics memory in the Gigabyte BIOS with a current maximum of 2GB, although we are told future BIOS releases will support 4GB and 8GB. We found the best strategy was to leave the UMA setting on Auto as there were times when 2GB gave a benefit and others when it was a hindrance.
We were impressed by the Vega 8 and 11 graphics cores in these APUs, however the new technology offered no direct benefit over Polaris in terms of performance. Having said that, while we are used to Vega 56 and 64 demanding massive levels of power and producing excessive levels of heat, it seems clear that Vega 8 and 11 are running at the correct clock speeds for this technology in this application, The result is that AMD has been able to shoehorn a serious graphics core into a tiny package and the results are impressive.
