- Hygon’s C86-5g ruptures are released from AMD Zen, unleashing 128 local muscle cores
- SMT4 drives each nucleus to execute four wires, stacking up to 512 threads in total
- AVX-512 instructions make it a strong adjustment for AI, analysis and scientific computing
Hygon, a key player in the Chinese semiconductor industry, is advancing its line of server processors with the next C86-5G, a high-performance flagship, with 128 cores and 512 wires, positioning it to directly compete with the AMD’s Epyc and Intel’s Xeon platforms.
According to Techpowerup, this marks Hygon’s complete breakdown of AMD’s Zen architecture and the introduction of its first totally harvest design, the result of five years of domestic R&D in the development of the CPU.
The new alignment is possible through a simultaneous four -way multiprine (SMT4), which allows each nucleus to handle four threads.
Built for parallel and high performance workloads
Although SMT4 is not a new concept, it has appeared in processors such as Xeon Phi of Intel and IBM’s Power8, its use in a modern Chinese processor and developed by the country is a notable milestone.
The configuration of 128 nuclei in the C86-5G represents an important leap of its predecessor, the C86-4G, which had 64 cores and 128 threads using traditional SMT2.
Designed for business and servers workloads, the C86-5G has 16 DDR5-5600 memory channels, which can admit up to 1 TB using 64 GB DDR5 modules. This is a step forward of the 12 channels of the previous model of DDR5-4800.
In the connectivity front, while Hygon has not yet revealed the exact PCIE 5.0 LANE count, has confirmed the support for Compute Express Link 2.0 (CXL 2.0), aligning the chip with the industry standards used by EPYC 9005 (Turin) of AMD and the 5th XEON GEN of Intel (Emerald Rapid). The previous C86-4g has already offered 128 PCIE 5.0 lanes, so a similar or better support is expected.
Although the specific microarchitecture has not been detailed, Hygon states that it is based on a “improved self -developed micro -architecture” that follows Dhyana’s design based on ZEN of the first generation.
According to the company, the architecture offers an improvement of 17% in the instructions per cycle (CPI), although this still does not verify in the absence of reference tests.
The chip also admits the AVX-512 instructions for high performance computer tasks and is created to handle physical stress in demanding environments. It is expected that it admits memory modules of the standard server as RDIMM and is intended for large -scale data centers implementations.
While Hygon still follows AMD and Intel in the general performance, the technical specifications of the C86-5G, which include I/O capabilities, memory bandwidth, threaded and core count, place it in a competitive position.
Although there is still no official launch date, it is likely that development is underway, since the C86-4G has been in the market since 2024.
