Socket FM1 is a CPU socket for desktop computers used by AMD early A-series APUs ("Llano") processors and Llano-derived Athlon II processors. It was released in July 2011. Its direct successors are Socket FM2 (September 2012) and Socket FM2+ (January 2014), while Socket AM1 (January 2014) is targeting low-power SoCs.

  2. ^ Unified shaders : texture mapping units : render output units
  3. ^ To play protected video content, it also requires card, operating system, driver, and application support. A compatible HDCP display is also needed for this. HDCP is mandatory for the output of certain audio formats, placing additional constraints on the multimedia setup.
  4. ^ To feed more than two displays, the additional panels must have native DisplayPort support.[8] Alternatively active DisplayPort-to-DVI/HDMI/VGA adapters can be employed.
  5. ^ a b DRM (Direct Rendering Manager) is a component of the Linux kernel. Support in this table refers to the most current version.
