The first engineering sample of AMD's upcoming Ryzen ThreadRipper is reportedly here, with the Ryzen ThreadRipper 1920 processor rocking 12C/24T of CPU performance.
AMD's first Ryzen ThreadRipper 1920 chip will have its 12C/24T of power at 3.2GHz base clock, but we don't know what the boost clock will be under XKR. The higher-end 16C/32T processor without a name just yet, rumored as the ThreadRipper 1998X will have 3.4GHz base CPU clock, while under XFR it will hit 3.7GHz and hopefully, beyond.
There's also another 16C/32T chip at 3.1GHz base and 3.6GHz boost, another engineering sample. There's also the Ryzen 3 1200 processor, with its 4C/4T power at 3.1/3.6GHz for base/boost respectively.
This is what I've previously reported, with specs on the then-named Ryzen 9 chips:
ThreadRipper 16C/32T: Ryzen 9 1998X/1998
The new HEDT chips will be led by the flagship Ryzen 9 1998X and Ryzen 9 1998, offering 16C/32T at 3.5GHz base and 3.9GHz boost CPU clocks, while coming in with a 155W TDP - 5W less than Intel's next-gen Core i7-7920X which is a 12C/24T part. The Ryzen 9 1998 on the other hand will retain the 16C/32T power, but at 3.2/3.6GHz for base/boost clocks, respectively - on the same 155W TDP.
ThreadRipper 14C/28T: Ryzen 9 1977X/1977
AMD's purported 14C/28T processors will arrive as the Ryzen 9 1977X with a base 3.5GHz clock and boost of 4.1GHz on a 155W TDP. The smaller Ryzen 9 1977 will hit 3.2GHz base and 3.7GHz boost, on a lower 140W TDP.
ThreadRipper 12C/24T: Ryzen 9 1976X/1956X/1956
The mid-range ThreadRipper will still have 12C/24T and will include 3 SKUs in total, starting with the Ryzen 9 1976X with base and boost clocks of 3.6GHz and 4.1GHz, respectively, on a 140W TDP. The Ryyzen 9 1956X will have the same 12C/24T, but at 3.2GHz and 3.8GHz for base/boost, at 125W. The smaller Ryzen 9 1956 is a 125W part at 3GHz and 3.7GHz on base/boost.
ThreadRipper 10C/20T: Ryzen 9 1955X/1955
AMD will have its lowest ThreadRipper SKUs as 10C/20T parts with the Ryzen 9 1955X offering 3.6GHz and 4.0GHs base/boost CPU clocks, while the Ryzen 9 1955 will rock 3.1/3.7GHz CPU clocks.
