- The C86-5G of Hygon is released from Amd Zen, releasing 128 local muscle nuclei
- SMT4 feeds each nucleus to execute four threads, stacking up to 512 threads in total
- The AVX-512 instructions make it a strong adjustment for AI, scientific analysis and computer science
Hygon, a key player in the Chinese semiconductive industry, advances its range of servers processors with the next C86-5G, a flagship and high performance processor with 128 cores and 512 threads, positioning it to compete directly with EPYC and XED and Intel platforms.
According to TechPowerUp, this marks the complete break of Hygon from Zen architecture of AMD and the introduction of its first entirely local design, the result of five years of domestic R&D in the development of the processor.
The new range is made possible through simultaneous four -track multithreading (SMT4), allowing each nucleus to manage four threads.
Built for parallel workloads and high speed
Although SMT4 is not a new concept – it appeared in processors like Xeon Phi of Intel and Power8 of IBM – its use in a modern Chinese processor and developed in the country is a notable step.
The configuration of 128 cores in the C86-5G represents a major jump of its predecessor, the C86-4G, which had 64 cores and 128 threads using traditional SMT2.
Designed for corporate and server workloads, the C86-5G has 16 DDR5-5600 memory channels, potentially taking up to 1 TB using DDR5 64 GB modules. This is a step compared to the 12 channels of the previous model of DDR5-4800.
On the front of connectivity, although Hygon has not yet disclosed the exact number of PCIe 5.0 tracks, he confirmed the support of Compute Express Link 2.0 (CXL 2.0), aligning the chip with the standards of the industry used by Epyc 9005 (Turin) of AMD and Turin) and the 5th generation of Intel (Emerald Rapids). The previous C86-4G already offered 128 PCIE 5.0 lanes, so similar or best support is expected.
Although the specific microarchitecture has not been detailed, Hygon declares that it is based on an “improved self-developed microarchitecture” which follows the Dhyana design based on the first generation Zen.
According to the company, architecture offers an improvement of 17% of the instructions per cycle (IPC), although this is not checked in the absence of reference tests.
The chip also supports the AVX-512 instructions for high-performance computer tasks and is designed to manage physical stress in demanding environments. It should support the standard server memory modules such as RDIMMS and is intended for deployments of large -scale data centers.
While Hygon always follows AMD and Intel in overall performance, the technical specifications of the C86-5G, including the capacities of E / S, the memory bandwidth, the thread and the number of nucleus, place it in a competitive position.
Although there is not yet an official launch date, development is probably well underway, since the C86-4G has been on the market since 2024.
