Threadripper, or Ryzen Threadripper, is a brand of HEDT (High-end Desktop) multi-core x86-64 microprocessors designed and marketed by Advanced Micro Devices (AMD), and based on the Zen microarchitecture[3]. It consists of central processing units (CPUs) marketed for mainstream and workstation segments, and as such comes in two line-ups Threadripper and Threadipper 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 develop the benefits of Ryzen and EPYC CPU roadmaps, so as 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.[4]

Characteristics[edit]

Threadripper chips have higher core counts, increased power requirements, support faster memory, and more expension opportunities. They 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, and adds support for increased RAM capacity (2TB vs 1TB) and memory channels (8 channels vs 4 channels) when compared to regular Threadripper. It is targeted at the workstation market.
