The AMD Ryzen Threadripper 1900 is a desktop processor with 8 cores, that was never released. It is part of the Ryzen Threadripper lineup, using the Zen (Whitehaven) architecture with Socket SP3r2. Thanks to AMD Simultaneous Multithreading (SMT) the core-count is effectively doubled, to 16 threads. Ryzen Threadripper 1900 has 32 MB of L3 cache and operates at 3.1 GHz by default, but can boost up to 3.7 GHz, depending on the workload. AMD is building the Ryzen Threadripper 1900 on a 14 nm production process using 9,600 million transistors. The silicon die of the chip is not fabricated at AMD, but at the foundry of GlobalFoundries. You may freely adjust the unlocked multiplier on Ryzen Threadripper 1900, which simplifies overclocking greatly, as you can easily dial in any overclocking frequency.
With a TDP of 125 W, the Ryzen Threadripper 1900 consumes a lot of power, so good cooling is definitely needed. AMD's processor supports DDR4 memory with a quad-channel interface. The highest officially supported memory speed is 2666 MT/s, but with overclocking (and the right memory modules) you can go even higher. For communication with other components in the machine, Ryzen Threadripper 1900 uses a PCI-Express Gen 3 connection. This processor does not have integrated graphics, you will need a separate graphics card.
Hardware virtualization is available on the Ryzen Threadripper 1900, which greatly improves virtual machine performance. Programs using Advanced Vector Extensions (AVX) will run on this processor, boosting performance for calculation-heavy applications. Besides AVX, AMD is including the newer AVX2 standard, too, but not AVX-512.
