HEDT assault begins with a trio of giant TR4 chips priced from $549. AMD's high-end desktop (HEDT) Ryzen Threadripper processors are now available for pre-order ahead of retail availability starting August 10.

The enthusiast additions to the Ryzen range extend the reach of the Zen architecture from $109 for the Ryzen 3 1200 right the way up to $999 courtesy of the new Ryzen Threadripper 1950X. AMD's range-topping part has been on the cards for some time, as has the second-rung Ryzen Threadripper 1920X, and the manufacturer is now revealing some of the finer details including TDP and cache size, as well as confirmation of a third HEDT chip, the $549 Ryzen Threadripper 1900X, due August 31.
