Socket FM2+ (FM2b) is a CPU socket used by AMD's desktop "Kaveri" APUs (Steamroller-based) and Godavari APUs (Steamroller-based) to connect to the motherboard. The FM2+ has a slightly different pin configuration to Socket FM2 with two additional pin sockets. Socket FM2+ APUs are not compatible with Socket FM2 motherboards due to the aforementioned additional pins. However, socket FM2 APUs such as "Richland" and "Trinity" are compatible with the FM2+ socket.
- ECC DIMMs are supported on Socket FP3 but not supported on the Socket FM2+ package. GDDR5 or HBM memory are not supported.
- There are 3 PCI Express cores: one 2 ×16 core and two 5 ×8 cores. There are 8 configurable ports, which can be divided into 2 groups:
- Gfx-group: contains 2 ×8 ports. Each port can be limited to lower link widths for applications that require fewer lanes. Additionally, the two ports can be combined to create a single ×16 link.
- GPP-group: contains 1 ×4 UMI and 5 General Purpose Ports (GPP).

Its mobile counterpart is Socket FP3 (µBGA906).
The 4 holes for fastening the heatsink to the motherboard are placed in a rectangle with lateral lengths of 48 mm and 96 mm for AMD's sockets Socket AM2, Socket AM2+, Socket AM3, Socket AM3+ and Socket FM2. Cooling solutions should therefore be interchangeable.

- APU models: A8-7680, A6-7480. CPU only: Athlon X4 845.
- Unified shaders : texture mapping units : render output units
- 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. Alternatively active DisplayPort-to-DVI/HDMI/VGA adapters can be employed.
- DRM (Direct Rendering Manager) is a component of the Linux kernel. Support in this table refers to the most current version.
