AMD isn't slowing down its pace of ratcheting up the power with its Ryzen Threadripper CPUs. The company today took the wraps off of its latest lineup, dubbed the Ryzen Threadripper Pro. Built for workstation PCs, the Threadripper Pro series packs a ton of power, incuding the highest number of cores available in a single workstation chip.

The Threadripp Pro lineup is made up of four entries: the 3990WX, 3975WX, 3955WX, and 3945WX. At the top end, you can expect 64 cores, 128 thread, 128 PCIe 4 lanes, and 8-channel memory bandwidth. That's combined with up to a 4.2GHz clock speed and support for up to 2TB of memory.
