AMD has launched its third and most affordable Threadripper CPU, the Ryzen Threadripper 1900X. It is now available to purchase online at places like Amazon and Newegg for $549.

The Threadripper 1900X doesn't go nuts with core and thread counts—it has 8 cores and 16 threads, versus the 12C/24T Threadripper 1920X ($800) and 16C/32T Threadripper 1950X ($1,000). That is the same core and thread count as AMD's Ryzen 7 1800X, but at nearly double the TDP (180W versus 95W).
