Hygon C86-5G Specifications

The C86-5G, in contrast to its predecessor, the C86-4G, features up to twice as many cores and four times as many threads. Unfortunately, Hygon has not disclosed the specific microarchitecture utilized in the C86-5G, only mentioning that it has been “upgraded again.” Consequently, the chipmaker claims that the C86-5G will significantly improve instructions per cycle (IPC) by more than 17%.

Hygon has come a long way since its first-generation server processor, which was built on the Dhyana microarchitecture derived from AMD’s Zen IP. However, it seems to be a thing of the past, as Hygon’s roadmap indicates that since the C86-4G model, the company has adopted a “new self-developed microarchitecture.” Consequently, the C86-5G is said to employ an enhanced version of this mysterious microarchitecture.

The C86-5G has a rich feature set, including AVX-512 instructions and 16-channel DDR5-5600 support, up from the 12-channel DDR5-4800 configuration on the C86-4G. The former can substantially help the C86-5G power through server and enterprise workloads. Meanwhile, supporting 16 memory channels will allow Hygon’s upcoming platform to house an enormous amount of memory. The manufacturer didn’t specify which DIMM formats the C86-5G can handle, but being a server chip, it should support RDIMMs and such. But even with conventional DDR5 memory modules that have scaled up to 64GB per module, the C86-5G can have up to 1TB of DDR5-5600 at its disposal.

The earlier C86-4G model offers 128 PCIe 5.0 lanes for connectivity, matching the capacity of AMD’s fourth-generation EPYC 7004 (codenamed Genoa) chips. Although the number of PCIe 5.0 lanes for the C86-5G is yet to be disclosed, Hygon has confirmed that the new flagship will support Compute Express Link 2.0 (CXL2.0). This positions the C86-5G competitively alongside the latest AMD EPYC 9005 (codenamed Turin) and Intel’s 5th Gen Xeon (codenamed Emerald Rapids) processors in terms of interconnect standards.

The C86-4G has presumably been available since last year, suggesting that Hygon probably began development on the C86-5G already. However, since the roadmap is quite ambitious and lacks specific dates, we cannot determine the current status of the C86-5G.

Before the tariff conflict with the U.S., China was already pursuing technological self-sufficiency. The tariffs merely accelerated the nation’s efforts to reach this goal, with companies like Hygon vital to the process. It’s unrealistic to believe Hygon can launch a chip that rivals AMD’s and Intel’s performance levels. Nonetheless, the C86-5G seems to compare well with competitors in terms of features, at least. Considering the current landscape, we expect to see C86-5G benchmarks soon.
