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.

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] .

Zen is a family of computer processor microarchitectures from AMD, first launched in February 2017 with the first generation of its Ryzen CPUs. It is used in Ryzen (desktop and mobile), Ryzen Threadripper (workstation and high end desktop), and Epyc (server). Max. CPU cores.

The chiplet architecture enables leading edge 7nm [1] CPUs for multiple markets, while retaining backward compatibility to complex IO and memory subsystems in a scalable design with high reuse for improved time-to-market. A key benefit is the heterogeneous technology deployed between the CPUs and the IO/mixed-signal IP.

X570 的南桥是 14nm 的 IO die，所以发热是十分巨大的，南桥一般都会配备一个风扇 (除了 ROG C8DH)。 X570 可以提供最多 16 条 PCIE4.0 (八条和 SATA 公用)、12 个 SATA (八个和 PCIE 公用)、八个 USB3.1 接口这个扩展能力已经不输某些 HEDT 平台，也是顶级主板的御用芯片组。

2023年3月5日 · Although we've known most of the details of AMD's I/O die in its Zen 4 processors, until now, AMD hadn't shared a die shot of the cIOD, but thanks to its ISSCC 2023 presentation, we not only have a die shot of the cIOD, but some friendly people on the internet have also made annotations for us mere mortals.

• INNOVATIVE FUTURE: The hybrid multi-die architecture puts us on a path of rapid innovation Our 3D V-Cache technology adds cache memory to CPU dies today, but we don’t see ourselves limited to adding static capacity with our solderless connections What if we could add specialized processing units to the CPU die? SMKE. READY TO CONNECT?

2024年8月14日 · Am4 是 2016 年发布的 AMD 芯片组，取代了 Am3+。 它支持 AMD 的 Ryzen 插槽，并得到了主板制造商的广泛采用，使其成为市场上最受欢迎的 AMD 芯片组。 AMD 专门为其 Zen 4 处理器设计了AM5 插槽，以取代自 2016 年以来一直使用的当前 AM4 插槽。 AM5 插槽与其前代产品相比有多项改进，例如支持 DDR5 内存、PCIe 4.0/5.0 以及改进的电源传输。 AM5 插槽相对于其前身 AM4 具有的一些主要优势包括： DDR5 内存支持： AM5 插槽将支持 DDR5， …

2023年6月6日 · We take a deep dive into the microarchitecture used in the latest AMD Ryzen 7000 CPU lineup, from cache changes to the new front end and AM5 socket. The latest AMD CPU architecture is called Zen 4, and it sees AMD mounting a full-frontal assault on Intel with its Ryzen 7000 series of CPUs.

"T-Topology" memory trace layout does great with 4 DIMMs but is less effective with 2 DIMMs, and makes this board weak at ram relative to more recent boards. Notable Features: Full control of all the minor voltages needed to fight cold issues on Ryzen.
