Wendell discovers the problem why ryzen threaddripper 2990wx performs 50% less on windows

Wendell, a computer expert, has finally discovered the problem where the Windows kernel makes the AMD Ryzen Threaddripper 2990WX processor perform up to 50% less than it should for the Microsoft system. In addition, it has managed to implement a small application capable of solving this error immediately.

Windows kernel is to blame for Ryzen Threaddripper 2990WX performing 50% less

We already knew for a while that the AMD Ryzen Threaddripper 2990WX processor had a problem in Windows that made it get less performance than other systems like Linux. This was noted in typical CPU benchmark tests and tests with compressors like 7-Zip under the Microsoft system.

The AMD Ryzen Threaddripper 2990WX is still today the most powerful processor in the AMD desktop range. A beast that is basically the union of two saddles of Zen architecture to give us 32 cores and 64 processing threads under a 12 nm architecture with no less than 64 MB of L3 cache. The processing frequency is 3.2 GHz with a turbo mode that raises it to 4.2 GHz.

Well, the problem that Wendell has detected is due precisely to the configuration of these two silicons and the NUMA technology for managing shared memory between them. Due to this design with two dies without direct access to RAM, unlike other Threadripper processors, the Ryzen 2990WX uses a quad-NUMA configuration, which has allowed them to create the world's first 32-core consumer processor. Precisely in the use of these four NUMA channels is the problem, since it has been determined that the Windows kernel is not capable of using them correctly.

To be sure of that, Wendell also tested the AMD EPYC 7551, which uses 32 cores and 64 threads and an eight-channel NUMA configuration. The result was practically the same, lower performance on Windows platforms and perfect performance under Linux.

All this is perfectly explained in a video made by Wendell himself, so if you control English, we recommend you watch it in its entirety.

Problem identified, isolated and Solved?

Well apparently yes. After explaining the tests to which the processors were subjected in the video long and attentively, Wendell, with the help of another partner, have managed to create a tool called CorePrio that solves this problem immediately in Windows 10.

After a call to the application, the results they have obtained using the Indigo benchmarking software are radically opposite to the previous ones, providing the same performance as in Linux and can then take advantage of 100% of the performance of these two processors.

Definitely good news for those who have emptied their pockets on this AMD Ryzen 2990WX. The fact of having the best processor on the market yielding half of its possibilities is something, at least, unpleasant. Our congratulations to this team for being able to solve what a huge multinational company such as Microsoft has not been able to do. There are no words to comment on Microsoft and "the best operating system they have created". Are you an AMD Ryzen Threaddripper 2990WX user? What do you think about the discovery of this problem and whose is the culprit? Feel free to write in the comments.
