Hexin Technology, a prominent CPU developer in China, announced the successful power-on of its HX-C2000 TC2, the second-generation test chip for its forthcoming HX-C2000 processor. Setting itself apart from current server CPU designs, Hexin opted for IBM’s open source Power ISA, steering away from the prevalent x86, Arm, and RISC-V instruction set architectures. The HX-C2000 chip, equipped with a staggering 110 billion transistors, aims to cater to diverse applications such as artificial intelligence (AI), big data, and cloud computing.
While most server CPUs in China rely on x86 processors from Intel and AMD, the country’s ongoing endeavor to overcome US sanctions has prompted a quest for alternative processor designs. Hexin’s adoption of IBM’s Power ISA introduces a unique approach to the market, leveraging an open source architecture that debuted in China back in 2014. With a team of 400 professionals, many of whom previously worked at IBM’s high-performance R&D center, Hexin has skillfully reconstructed IBM’s closed design methodology using its own chip design tools, architecture, and design flow.
China’s server market is projected to reach a substantial value of $30.8 billion by 2023, predominantly driven by x86-based servers. However, faced with the restrictions imposed by the US government on China’s AI and high-performance computing sectors, there is an increasing impetus to cultivate homegrown CPUs and GPUs for consumer PCs and servers.
Hexin’s latest achievement, the TC2 silicon, signals a significant milestone toward the eventual production of the entire HX-C2000 processor. Although the company has not specified an exact timeframe for the delivery of final chips, their successful power-on of the test chip, HX-C2000TC2, within just four hours underscores the silicon’s readiness. Hexin has expressed confidence that the chip has met or exceeded all of its expectations.
While server programs are compatible with the RISC ISA, further optimization would be required to maximize the potential of Hexin’s HX-C2000, particularly for modern workloads such as AI, HPC, and cloud computing. Thus, Hexin acknowledges the need for extensive software support and compatibility efforts before the CPU can be effectively utilized in the targeted markets.
