Why run Ansys applications on AMD processors?

Companies are investing in high-performance computer infrastructure with the best-performing processors to maximize the value of game-changing Ansys applications. The 4th Gen AMD EPYC™ processors deliver the optimal architecture for Ansys and help reduce constraints on the number, size, and complexity of simulation models while helping provide faster time to results. In addition, with AMD CPU-based systems, engineers can improve design quality and prototype performance and significantly reduce total cost of ownership (TCO) using fewer servers to do the same work, helping reduce power and lower related emissions.

How does AMD improve Ansys applications’ performance?

Compared to the prior generation, the new AMD EPYC™ 4th Gen processors achieve better performance for Ansys applications with up to 50% more cores, higher frequencies, support for AVX-512 instructions, more memory bandwidth, and faster PCIe® and Infinity Fabric™ data transfer rate. In addition, optimizing Ansys applications with AMD compilers and libraries can help enhance performance further.

AMD Processors for Ansys

Koi Computers' System configurations

Below are our recommendations for Ansys applications with 4th Gen AMD EPYC™ processors with 12 memory channels per socket and support for AVX-512 instructions. This can deliver high throughput per node for Ansys applications since they benefit from multicore parallelism and greater memory bandwidth.
