AMD is attacking Intel's high-end desktop chips with the announcement of a third Ryzen Threadripper CPU priced at $549.

The Ryzen Threadripper 1900X will feature 8-cores and 16-threads of computing power, but unlike the Ryzen 7-series, which also features 8-cores and 16-threads, the 1900X will slip into the company's X399 socket.

The Ryzen Threadripper 1900X supports 64 PCIe lanes, as well as quad-channel memory configurations. Intel's newest Skylake-X Core i7-7820X (8-core) CPU is featuring 28 lanes of PCIe.

The Ryzen Threadripper 1900X will have a base clock of 3.8GHz and a boost clock of 4GHz. That's a bit higher than the 12-core Ryzen Threadripper 1920X, which has a 3.5GHz base clock and 4GHz boost, as well as the 16-core Ryzen Threadripper 1950X, which has a 3.4GHz base clock and 4GHz boost clock.

AMD showed comparison benchmarks that put the top-end 16-core Ryzen Threadripper 1950X running about 55 percent to 15 percent faster than Intel's current top-end Core i9-7900X CPU. Both chips are roughly $1,000.

The company also said the 12-core Ryzen Threadripper 1920X would generally be faster in multi-threaded loads than the Core i9-7900X, even though it is $200 less.

Power consumption of Ryzen Threadripper will also be lower in some tasks thanks to its superior core count. AMD claims that the Threadripper 1950X will finish a workload faster than the Core i9, and then go idle while the Intel CPU is catching up.

The Ryzen Threadripper 1950X and 1920X are expected to be on store shelves by August 10, with the newly announced Ryzen Treadripper 1900X hitting shelves on August 31.

All three chips will come in a premium Threadripper packaging, which will also include a bracket adapter for most popular liquid coolers, as well as a torque wrench to properly install the CPU.

AMD also showed off a Ryzen Threadripper 1950X with all cores overclocked to 5.187GHz using liquid nitrogen. A CineBench R15 result of 4,122 is enough to break the world record for a 16-core CPU, AMD said. AMD said a Ryzen Threadripper 1950X being overclocked to 5.1GHz using liquid nitrogen broke the world record.
