Threadripper, or Ryzen Threadripper, is a brand of HEDT (high-end desktop) and workstation multi-core x86-64 microprocessors designed and marketed by Advanced Micro Devices (AMD), and based on the Zen microarchitecture.^[1] It consists of central processing units (CPUs) marketed for mainstream and workstation segments, and as such comes in two line-ups, Threadripper and Threadripper PRO respectively.

Background

Threadripper, which is geared for high-end desktops (HEDT) and workstations, was not developed as part of a business plan or a specific roadmap. Instead, a small team inside AMD saw an opportunity to give AMD the lead in desktop CPU performance. After some progress was made in their spare time, the project was greenlit and put in an official roadmap by 2016.^[2]^{[better source needed]}

Characteristics

Threadripper chips have higher core counts, increased power requirements, support faster memory, and more expansion opportunities. 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. When compared to non-HEDT CPUs:

Higher core count (up to 96 cores)
Higher power consumption
Additional memory channels
Increased RAM capacity
More PCIe lanes

Threadripper PRO

The Threadripper PRO line-up debuted with the 3000 series for workstations and adds support for increased RAM capacity (2TB vs 1TB) and memory channels (eight channels vs four channels) when compared to regular Threadripper. It is targeted at the workstation market.
