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.

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 ...
Steamroller is the AMD codename for its third-generation microarchitecture based on an improved version of Piledriver. Steamroller cores are found in the Socket FM2+ Kaveri based series of APUs and CPUs. Excavator is the codename for the fourth-generation Bulldozer core. [55]
Zen 4 is the name for a CPU microarchitecture designed by AMD, released on September 27, 2022. [4] [5] [6] It is the successor to Zen 3 and uses TSMC's N6 process for I/O dies, N5 process for CCDs, and N4 process for APUs. [7]
It made its debut as AMD's high-end processor brand on June 23, 1999. [1] Over the years AMD has used the Athlon name with the 64-bit Athlon 64 architecture, the Athlon II , and Accelerated Processing Unit (APU) chips targeting the Socket AM1 desktop SoC architecture, and Socket AM4 Zen (microarchitecture) .
