This article is part of the CPU socket series

"Llano"-branded products combine K10 with Cedar (VLIW5), UVD 3 video acceleration and AMD Eyefinity-based multi-monitor support of up to three DisplayPort-monitors.

"Trinity"- and "Richland"-branded products Piledriver with Northern Islands (VLIW4), UVD 3 and VCE 1 video acceleration and AMD Eyefinity-based multi-monitor support of up to four DisplayPort-monitors.

While the AMD desktop CPUs are available in a 722-pin package Socket AM1 (FS1b), it is not clear whether these desktop CPUs will be compatible with Socket FS1 or vice versa.

It is the last pin grid array socket for AMD's mobile processors - all mobile processors in microarchitectures succeeding Piledriver are exclusively available in BGA packaging, for example Steamroller-based mobile processors uses Socket FP3 socket, which is a µBGA socket. Intel also adopted same practice, starting with Broadwell microarchitecture.

  2. For FM2+ Excavator models: A8-7680, A6-7480 & Athlon X4 845.
  3. A PC would be one node.
  4. An APU combines a CPU and a GPU. Both have cores.
  5. Requires firmware support.
  6. No SSE4. No SSSE3.
  7. Single-precision performance is calculated from the base (or boost) core clock speed based on a FMA operation.
  8. Unified shaders : texture mapping units : render output units
  9. 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.
  10. 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.
  11. DRM (Direct Rendering Manager) is a component of the Linux kernel. Support in this table refers to the most current version.
