We tested both APUs with the supplied Gigabyte AB350N-Gaming-WiFi and a second motherboard of the same model when the first locked solid and refused to restart. AMD supplied a dual channel kit of G.Skill FlareX DDR4-3200MHz and we used a Sea Sonic Prime Titanium 600W Fanless power supply.
We compared the Vega graphics with two graphics cards from Sapphire. The Pulse Radeon RX 550 2GB has 640 Shaders (Polaris technology) at a maximum speed of 1071MHz so on paper it appears to fall somewhere between Vega 8 and Vega 11.
Sapphire Pulse RX 560 Pulse 4GB has 1024 Shaders (Polaris technology) and a core speed of 1300MHz that should be a clear upgrade for ether APU.
