Windows 10 Pro can't handle the AMD Threadripper 3990X's 128 threads

AMD recently released its monstrous Threadripper 3990X. It's a 128-thread CPU with a Max boost clock speed of 4.3GHz. It's an extremely powerful fleck, simply to go the virtually of that ability, you'll need to upgrade to something to a higher place Windows 10 Pro. In Anandtech's review of the Threadripper 3990X, they noticed that systems running Windows ten Pro split the CPU into two groups of 64 threads.

When dissever into two groups, a PC can still use all 128 threads, but a single program cannot. When a program runs, it goes into i of the processor groups. The system places the program in the group that's less busy to avoid congestion. A program tin just use the threads inside the group information technology's placed in, meaning that it's capped at 64 threads. Developers can make programs processor group aware, which gets around this upshot, but if a program isn't built for this type of setup, information technology can just access 64 threads.

You lot can also somewhat go effectually this result past disabling simultaneous multithreading. This volition brand it so your system only has one processor grouping with 64 cores. The downside of this is that some performance is lost, according to Anandtech's benchmarks.

The real style to get around this is to run an operating organization built to handle this many threads. Microsoft didn't build Windows 10 Domicile or Windows 10 Pro to handle 128 threads. That'due south reasonable considering the vast bulk of systems running those two versions of Windows will never run across anywhere about 128 threads.

If you desire to utilize the full ability of all 128 threads while running Windows, you can run Windows 10 Pro for Workstations or Windows x for Enterprise.

In that location'due south a chance that the result could go away, however. According to comments on Ars Technica (via TechRader), Windows 10 Pro has an update that allows it to see the 3990x's 128 threads correctly.

This processor packs 64 cores, 128 threads, and has a max base clock of 4.3GHz. It as well supports NVMe RAID so you lot can combine up to six NVMe disks.

An internet connection will before long exist required when setting up Windows 11 Pro

Microsoft has announced that later this year, users will be required to connect to the cyberspace and sign-in with a Microsoft Business relationship during the out of box setup experience on Windows 11 Pro. Microsoft has already been enforcing this requirement on Windows 11 Habitation since launch last October, and Windows 11 Pro is now expected to follow suit shortly.
