Chinese Semiconductor Company Phytium Introduces New Data Center Processor

Phytium, a Chinese semiconductor company that faced U.S. government sanctions from 2021, has introduced its latest data center processor, the 64-core Feiteng Tengyun S2500. This processor is specifically designed for cloud and high-performance computing applications.

The Feiteng Tengyun S2500 comes with several notable features, including a large-capacity shared L3 cache, enhanced security capabilities for cloud servers, and improved memory subsystem reliability.

The processor is powered by 64 FTC661 cores developed by Phytium, which are based on Armv8 ISA. It boasts 64 MB of L3 cache and 512 KB of L2 per core, resulting in a total of 96 MB of processor cache.

Compared to the previous generation line, the S2500 offers an increased L3 cache and TDP of 150 Watts, up from the previous 90 Watts.

This release marks Phytium's first new CPU in several years, leading to questions about its production capacity and access to foundries due to the sanctions it faces. The manufacturing foundry for the Feiteng Tengyun S2500 remains unknown, and more information is expected to be revealed as units are shipped. Currently, only display units have been seen.

Despite these challenges, Phytium has continued its hardware development efforts and has expressed interest in collaborating with Huawei to unify hardware and software ecosystems. However, this collaboration has yet to materialize.
