Threadripper, or Ryzen Threadripper, is a brand of high-end desktop (HEDT) 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) and comes in two line-ups, Threadripper and Threadripper PRO.

Background#edit

Threadripper, which is geared for high-end desktops (HEDT), 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]

Characteristics#edit

Threadripper chips have higher core counts, increased power requirements, support faster memory, and more expansion opportunities. 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#edit

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