What you need to know

  • AMD today launched its new Ryzen Threadripper Pro series.
  • Built for workstations, the lineup packs up to 64 threads, 128 PCIe 4 lanes, and 8-channel memory support.
  • The first workstation with these new chips is Lenovo's ThinkStation P620.

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.

The bare specs are also paired with enhanced security features. Here's a look at the highlights from AMD:

  • AMD PRO security – Layers of built-in security features to help protect sensitive data
  • AMD PRO manageability – Simplified deployment, imaging, and management compatible with user's current infrastructure
  • AMD Memory Guard – Full memory encryption to help prevent physical attacks on sensitive data.
  • AMD PRO Business Ready – 18 months of planned software stability and 24 months of planned availability

Here's a look at how each of the chips in the Threadripper Pro lineup compares in terms of specs.

The first workstation to sport AMD's new Ryzen Threadripper Pro series is Lenovo's ThinkStation P620. It's expected to launch in September starting at $4,599. We also expect to see more PC manufacturers announce new workstations with Threadripper Pro series CPUs as we draw closer to fall.

  • A lot of the listed specs differ from AMD's website
  • Are you sure you are looking at the PRO on the website? I haven't checked myself, just asking since there is already a 64 core non-pro threadripper available.
