Russia unveils Irtysh CPU based on Loongson's LoongArch architecture
Russia's Tramplin Electronics has introduced the Irtysh processor, developed under full authorization from China's Loongson Zhongke. The chip is based on the LoongArch LA664 core and marks the first openly licensed use of this architecture outside China.
Three versions are planned:
- 16-core S616 at up to 2.2 GHz
- 32-core S632 at up to 2.1 GHz
- 64-core S664 at up to 2.0 GHz
Peak floating-point performance ranges from 844.8 GFLOPS to 3072 GFLOPS, comparable to Intel's previous-generation Xeon Silver processors.
Tramplin Electronics completed the technology transfer in October 2025, securing rights to independently modify and expand the architecture. The company also obtained DDR4 memory and PCIe 4.0 physical layer technology licenses. Production will take place in Russia, with a target of 30,000 units in the first year. Early 2026 will see Russian companies launching complete systems based on Irtysh, with operating systems already adapted to the architecture.
Loongson's LoongArch instruction set, introduced in 2021, is fully independent and controllable, free from Western technology ties. It has become the third major global ecosystem alongside x86 and Arm. Loongson previously announced that the architecture would be permanently open and free for licensing, allowing customization by partners.
Irtysh processors are designed to meet Russia's demand for secure, autonomous computing systems. They include self-developed security modules and are expected to support both domestic and international markets. Performance is benchmarked against Loongson's own 3C6000 series, which can rival Intel's Xeon Platinum 8380 in certain configurations.
Tramplin Electronics is a Russian technology company headquartered in Omsk Oblast. It operates under the Springboard Group, founded by entrepreneur and philanthropist Svyatoslav Kapustin. The group's business spans technology, education, public welfare, construction, and media. Tramplin Electronics has previously invested in local processor projects but faced setbacks due to sanctions. By partnering with Loongson, the company aims to establish Russia's first fully independent CPU ecosystem, reducing reliance on foreign technology and strengthening national information sovereignty.
