Socket FM1
CPU socket for AMD CPUs
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.
Chipsets
For available chipsets consult Fusion controller hubs (FCH) .
Available APUs
APU's using Socket FM1 are AMD's Lynx platform.
Please consult List of AMD accelerated processing units for concrete product denominations.

^ For FM2+ Excavator models: A8-7680, A6-7480 & Athlon X4 845.
^ A PC would be one node.
^ An APU combines a CPU and a GPU. Both have cores.
^ Requires firmware support.
^ a b Requires firmware support.
^ No SSE4. No SSSE3.
^ Single-precision performance is calculated from the base (or boost) core clock speed based on a FMA operation.
^ Unified shaders : texture mapping units : render output units
^ a b 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.
^ To feed more than two displays, the additional panels must have native DisplayPort support.[ 10] Alternatively active DisplayPort-to-DVI/HDMI/VGA adapters can be employed.
^ a b DRM (Direct Rendering Manager ) is a component of the Linux kernel. Support in this table refers to the most current version.
