The AMD Athlon X4 850 is a quad-core desktop processor for Socket FM2+, based on the Godavari refresh of the Kaveri design with the integrated graphics disabled, so a discrete graphics card is required.

Notes
Windows 10 is supported. No Steamroller-based processor appears on Microsoft's Windows 11 supported-processor lists, which begin with the AMD Ryzen 2000 series, so Windows 11 is not supported. Current Linux distributions run without restriction.
