Zen 4c is a variant of Zen 4 featuring smaller Zen 4 cores with lower clock frequencies, power usage, reduced L3 cache per core, and is intended to fit a greater number of cores in a given space. Zen 4c's smaller cores and higher core counts are designed for heavily multi-threaded workloads such as cloud computing .
Zen 4c is designed to have significantly greater density than standard Zen 4 while delivering greater power efficiency. This is achieved by redesigning Zen 4's core and cache to maximise density and compute throughput. It has 50% less L3 cache than Zen 4 and is not able to clock as high.
AMD Zen 4 Family 19h – fourth generation Zen architecture, in 5 nm process. [5] Used in Ryzen 7000 consumer processors on the new AM5 platform with DDR5 and PCIe 5.0 support. Adds support for AVX-512 instruction set. AMD Zen 5 Family 1Ah – fifth generation Zen architecture, in 4 nm process. [6] Adds support for full-width AVX-512 pipeline.
On 27 September 2022, AMD officially launched their Ryzen 7000 series of central processing units, based on the TSMC N5 process and Zen 4 microarchitecture. [37] Zen 4 marked the first utilization of the 5 nm process for x86-based desktop processors. In December 2022 AMD also launched the Radeon RX 7000 series of graphics processing units based ...

Socket AM5 (LGA 1718) is a zero insertion force flip-chip land grid array (LGA) [1] CPU socket designed by AMD that is used for AMD Ryzen microprocessors starting with the Zen 4 microarchitecture. [ 2 ] [ 3 ] AM5 was launched in September 2022 and is the successor to AM4 .
Bristol Ridge (Excavator core supporting DDR4) (2016) (and Stoney Ridge implements Zen microarchitecture but utilizes the same Socket.) Low-power architecture; Bobcat, Jaguar, Puma (2011–present) [ edit ]
However, such releases never became the basis for the development of coreboot beyond AMD's family 15h, as they were subsequently halted. [2] AGESA became particularly relevant with the AM4 platform, which AMD designed for futureproofing, and as of May 2019 has served as the base for three different generations of CPUs based on its Zen architecture.
