The evolution of server CPUs has taken a significant leap with the introduction of the Hygon C86-7490 processor, which boasts a notable expansion in core count and memory support. This CPU, based on a collaboration involving AMD’s Zen core IP, targets China’s server market, balancing domestic demand with technological advancements.
Hygon’s Latest CPU Offering: A Glimpse into the C86-7490
Hygon’s C86-7490, a processor leveraging the Dhyana x86 IP and similar to AMD’s Zen+, marks a substantial progression in the CPU landscape. This latest model has doubled the core and thread count from its predecessors, jumping from a maximum of 32 cores and 64 threads up to an impressive 64 cores and 128 threads.
This jump in computing power is attributed to the configuration of four 16-core Compute Core Die (CCDs), which allows the C86-7490 to deliver substantial parallel processing capabilities, a critical factor in server environments. Further differentiating itself from the initial Zen and Zen+ EPYC CPUs, the C86-7490 includes two Input-Output Dies (IODs), expanding its data handling and connectivity options.
The Integration with SP5 Socket Platform
Such capacity to accommodate dual IODs is facilitated by the support for the SP5 socket platform, which provides a larger physical space than the SP3 sockets used in previous generations. This allows for the requisite room needed for both the multiple CCDs and IODs without feeling cramped.
Memory Capabilities: DDR5 Support
In terms of memory, the C86-7490 takes a significant leap forward with the adoption of DDR5 memory channels, with up to 12 possible channels. This memory support exceeds that of the earlier Zen EPYC CPUs that were limited to DDR4. With DDR5, the Hygon CPU stands poised to offer faster memory speeds and improved power efficiency, which are invaluable for complex server operations where data throughput and energy usage are key considerations.
Market Placement and Pricing
Designed explicitly for the Chinese market, the latest addition to the Hygon CPU lineup addresses the region’s demand while domestic policies emphasize local technology development. The Hygon C86 processors, with the C86-7490 as their flagship, are positioned at price points ranging from 35,000 RMB ($4900 approximately) to 42,000 RMB ($5900 approximately), reflecting their advanced features and market positioning.
Conclusion
The launch of the Hygon C86-7490 CPU is a significant development in the server CPU market, particularly for China. Bringing together 64 cores, dual IODs, DDR5 memory support, and SP5 socket compatibility, this processor sets a new benchmark for server-oriented CPUs tailored to suit the demands of large-scale, memory-intensive applications. As the technology evolves and the adoption of DDR5 becomes more mainstream, it serves as an example that might impact future global server CPU designs and trends.
