Socket AM4 is a PGA microprocessor socket used by AMD's central processing units (CPUs) built on the Zen (including Zen+, Zen 2 and Zen 3) and Excavator microarchitectures. [1] [2] AM4 was launched in September 2016 and was designed to replace the sockets AM3+, FM2+ and FS1b as a single platform.
Socket: AM4. All the CPUs support DDR4-2933 in dual-channel mode. All the CPUs support 16 PCIe 3.0 lanes. 4 of the lanes are reserved as link to the chipset. Includes integrated GCN 5th generation GPU. L1 cache: 96 KB (32 KB data + 64 KB instruction) per core. L2 cache: 512 KB per core. Fabrication process: GlobalFoundries 14LP.
There are currently 3 generations of AM4-based chipsets on the market. Models beginning with the numeral "3" are representatives of the first generation, those with "4" the second generation, etc. In addition to their traditional chipsets, AMD offers chipsets with "processor-direct access", exclusively through OEM partners.

This made Bulldozer a more superscalar design compared to Jaguar/Bobcat. However, due to K10's somewhat wider core (in addition to the lack of refinements and optimizations in a first generation design) the Bulldozer architecture typically performed with somewhat lower IPC compared to its K10 predecessors. It was not until the refinements made ...
The third generation of Ryzen processors launched on July 7, 2019, based on AMD's Zen 2 architecture, featuring significant design improvements with a +15 percent average IPC boost, a doubling of floating point capability to a full 256-bit-wide execution data path much like Intel's Haswell released in 2014, [20] a shift to an multi-chip module ...
Socket: AM4. All the CPUs support DDR4-2666 (DDR4-2933 Ryzen) in dual-channel mode. L1 cache: 96 KB (32 KB data + 64 KB instruction) per core. L2 cache: 512 KB per core. All the CPUs support 16 PCIe 3.0 lanes. Includes integrated GCN 5th generation GPU. Fabrication process: GlobalFoundries 14LP.
