The ultra-high-end CPU 'Ryzen Threadripper PRO 7995WX' with 96 cores and 192 threads was found to exhibit 1.2 times the performance in the Linux environment than in the Windows environment

AMD released the ultra-high-end CPU ``Ryzen Threadripper PRO 7995WX'' with 96 cores and 192 threads on November 22, 2023. It has been revealed that this CPU

has higher multi-core performance compared to previous generation models and rival CPUs , but it has been newly discovered that it exhibits higher performance in a Linux environment than in a Windows environment. Confirmed by media Phoronix.

AMD released the high-end CPU ``Ryzen Threadripper PRO 7000WX'' series and ``Ryzen Threadripper 7000'' series on November 22, 2023. Benchmark results that have already been published confirm that this series has higher performance than the previous generation series and rival series, and the flagship model Ryzen Threadripper PRO 7995WX requires multi-core performance. It has been confirmed that it exhibits overwhelming performance in tasks. Benchmark results for both series can be found in the articles below.

According to Phoronix, Linux is good at handling CPUs with a large number of cores, and it has been confirmed that the previous Threadripper series can demonstrate higher performance in a Linux environment than in a Windows environment. Phoronix conducted a benchmark test of Ryzen Threadripper PRO 7995WX in an environment with ``Windows 11 Pro 23H2'' and ``Ubuntu 23.10'' installed in order to confirm the difference in performance between Ryzen Threadripper PRO 7995WX in Linux and Windows environments.

Below is a graph comparing the number of drawing samples per second when rendering is performed with the 3D renderer 'LuxCoreRender'. The difference between Linux and Windows environments varies depending on what you are rendering.

Below is a graph comparing the number of frames drawn per second when rendering with the ray tracing library 'Intel Embree'. The Linux environment performed better under all conditions.

Below is a graph comparing the rendering time of models using the 3DCG tool 'Blender'. All models were able to complete rendering in a shorter time in the Linux environment.

Below is a graph comparing the second frame rate when encoding a video using the H.265 encoder 'Kvazaar'. The Linux environment performed better when encoding 4K video.

On the other hand, when encoding 1080p videos, the Windows environment performed better.

Below is a graph comparing the second frame rate when encoding a video using the AV1 encoder 'SVT-AV1'. When encoding with SVT-AV1, the Linux environment showed higher performance at both 4K and 1080p.

In addition to the above tests, Phoronix also conducts tests such as ``image noise removal'' and ``CPU mining,'' and concludes that Ryzen Threadripper PRO 7995WX exhibits 19.5% better performance in a Linux environment than in a Windows environment.
