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.

Socket AM4. Mobile: Dual-channel DDR4 or LPDDR4. Desktop: Dual-channel DDR4. Ryzen 3 (4300G, 4300GE, 4350G, 4350GE, Pro 4450U) Yes 2500–3800 (3700–4200 boost)
In December 2019, AMD started producing first generation Ryzen products built using the second generation Zen+ architecture. [41] An example is the Ryzen 5 1600, with new batches having an "AF" identifier instead of its usual "AE", essentially being an underbinned Ryzen 5 2600 with the same specifications as the original Ryzen 5 1600.
