Socket AM1

Socket AM1 is a socket designed by AMD, launched in April 2014^[1] for desktop SoCs in the value segment. Socket AM1 is intended for a class of CPUs that contain both an integrated GPU and a chipset, essentially forming a complete SoC implementation, and as such has pins for display, PCI Express, SATA, and other I/O interfaces directly in the socket. AMD's first compatible CPUs, designated as APUs, are 4 socketable chips in the Kabini family of the Jaguar microarchitecture, marketed under the Athlon and Sempron names and announced on April 9, 2014.^[2] Socket AM1 was initially branded as Socket FS1b before its release.^[3]

Socket AM1

Type	PGA-ZIF
Chip form factors	Flip-chip
Contacts	721
FSB protocol	PCI Express
Voltage range	1.4V
Processor dimensions	35mm × 35mm 1,225mm2
Processors	Desktop APU products Jaguar- and Puma-based (Athlon- and Sempron-SoCs)
Predecessor	FM2+
Successor	AM4
Memory support	DDR3
This article is part of the CPU socket series

The brand names are Athlon and Sempron. The underlying microarchitectures are Jaguar and Puma. All products are SoCs, this means the Chipset is on the die of the APU and not on the motherboard.

While the AMD mobile CPUs are available in a 722-pin package Socket FS1, it is not clear whether these notebook CPUs are compatible with Socket AM1 or vice versa.

Its mobile counterpart is Socket FT3 (BGA-769).

At least one board is supported by coreboot.^[4]
