AMD has released two new models of its Ryzen Threadripper high-end desktop processors, the 1950X and the 1920X.

The two models support the new SocketTR4 platform, sporting sixty-four PCIe lanes, quad channel DDR4 memory and AMD simultaneous multithreading (SMT). The Ryzen Threadripper 1950X delivers multi-processing power with support for 16 cores and 32 processing threads, while the Ryzen Threadripper 1920X provides 12 cores and 24 processing threads.

A third variant, the 8-core 16-thread Ryzen Threadripper 1900X, is expected to be available August 31.

Ryzen Threadripper 1950X and 1920X processors include 40MB and 38MB of processor cache, respectively. AMD said all Ryzen Threadripper processors from the Threadripper 1900X to the Threadripper 1950X feature the same quad-channel DDR4 memory bandwidth, 64 lanes of PCIe 3.0 connectivity and processor-direct SATA/NVMe/USB connectivity.

In addition, every Ryzen Threadripper processor is multiplier-unlocked to provide user flexibility. A full ecosystem of SocketTR4 X399 platforms, with native USB 3.1 Gen2 10GB/s connectivity, provide support for all Ryzen Threadripper processors at launch, with motherboards coming from manufacturers like ASRock, ASUS, Gigabyte and MSI.
