AMD today announced the pricing and (approximate) availability for Threadripper, its high-end desktop platform that was first unveiled in May.
The top-end part will be the Ryzen Threadripper 1950X: a 16 core, 32 thread chip with a base clock of 3.4GHz and a boost clock of 4.0GHz for $999.

Below that will be the 1920X: 12 cores, 24 threads, at 3.5/4.0GHz, for $799.
Both chips will use a 4094-pin socket called TR4 and the X399 chipset, offering 64 lanes of PCIe 3.0 connectivity and four channels of DDR4 memory.

Both have a notional power envelope of 180W.
Internally, the chip is essentially a doubled up version of the existing Ryzens: AMD’s basic building block is a unit of eight cores with 16 threads (split internally into two core complexes of four cores each).

Threadripper has two of these chips in each package; the Epyc server processor has four.
