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 .
AMD Zen+ Family 17h – revised Zen architecture (optimisation and die shrink to 12 nm). AMD Zen 2 Family 17h – second generation Zen architecture based on 7 nm process, first architecture designed around chiplet technology. [3] AMD Zen 3 Family 19h – third generation Zen architecture in the optimised 7 nm process with major core redesigns. [4]
Epyc server CPUs with Zen 4, codenamed Genoa, were officially unveiled at AMD's Accelerated Data Center Premiere Keynote on November 8, 2021, [37] and released a year later in November 2022. [38] They have up to 96 Zen 4 cores and support both PCIe 5.0 and DDR5. Furthermore, Zen 4 Cloud (a variant of Zen 4), abbreviated to Zen 4c, was also ...
In June 2022, Intel presented some details about the Intel 4 process (known as "7 nm" before renaming in 2021): the company's first process to use EUV, 2x higher transistor density compared to Intel 7 (known as "10 nm" ESF (Enhanced Super Fin) before the renaming), use of cobalt-clad copper for the finest five layers of interconnect, 21.5% ...
The MI300A is an accelerated processing unit (APU) that integrates 24 Zen 4 CPU cores with four CDNA 3 GPU cores, resulting in a total of 228 CUs in the GPU section, and 128 GB of HBM3 memory. The Zen 4 CPU cores are based on the 5 nm process node and support the x86-64 instruction set, as well as AVX-512 and BFloat16 extensions.

The Zen 4 core's pipelines use a high density leading-edge 5 nm process, which allows for larger instruction and data caches, deepending buffers and queues. [1] These chips use larger sockets such as TR4 , sTRX4 , sWRX8 , and sTR5 which support additional memory channels and PCI Express lanes.
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.
