Product overview

Released August 31, 2017, AMD’s Ryzen Threadripper 1900X is a first‑generation Threadripper (1000‑series, Zen) HEDT CPU for the TR4/sTR4 platform. It positioned as the entry to Threadripper, built to deliver the platform’s I/O and memory bandwidth without stepping up in core count.

With 8 cores/16 threads at 3.8/4.0 GHz (XFR to 4.2) and a 180 W TDP, it suits video editing, 3D rendering, and streaming on X399 motherboards. You get quad‑channel DDR4‑2667 with ECC support, 64 PCIe 3.0 lanes, and an unlocked multiplier; there’s no integrated graphics, so a discrete GPU is required. Notably, it’s an 8‑core CPU that still exposes the platform’s full 64 PCIe lanes.
