Threadripper

Threadripper, which is geared for high-end desktops (HEDT) and workstations, was not developed as part of a business plan or a specific roadmap.

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] 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.
