AMD Ryzen processor adopts Socket TR4 socket, which supports four channels of memory and provides up to 64 PCIe channels. This series adopts multi-chip module, code-named "Whitehaven".

In fact, four 8-core chips codenamed "Zeppelin" are packaged on the processor substrate, which is the second processor series with NUMA structure on the consumer computer platform. Because it is an 8-core chip, learning, programming and use are very smooth.

Framework:

1, Zen microarchitecture

Zen is x86-64 microarchitecture released by AMD in mid-20 16, replacing bulldozer microarchitecture and its improved version. Zen microarchitecture has two kinds of chips, one is an eight-CPU core chip code-named "Zeppelin" and the other is a four-CPU core +GPU chip code-named "Raven Ridge". ?

2.Zen+ microarchitecture

Zen+ is a slightly improved version of Zen, which is made by Grofonde's "12 nm" LP process, and is actually an improved version of the same factory's 14nmLPP process. The main improvement lies in the access performance of secondary cache, memory access performance and AMD SenseMI, thus achieving more stable step-by-step switching of frequency and voltage.
