- Zhaoxin KH-50000 architecture offers lingering shadows of past AMD connections
- DDR5 memory channels Expand capacity up to 3TB in server environments
- PCIE 5.0 support provides a noticeable leap in data connectivity
Zhaoxin introduced the Kaisheng KH-50000, its latest server processor that uses a chiplet-based design very similar Epic line AMDField
These similarities raise questions about whether the architecture reflects independent innovation or draws heavily on earlier connections between Chinese firms and Amd technology.
What makes this release more intriguing is that Zhaoxin has not yet revealed the power of the thermal design, an omission that has industry observers questioning how efficient this 96-core part will be.
Architecture and design choices
The KH-50000 uses Zhaoxin's “Century Avenue” architecture, which appears to descend from earlier Centaur technology designs.
The chip uses a chip arrangement consisting of twelve compute dies clustered around a large I/O, creating a total of 96 cores and 384 MB of L3 cache.
The second model reduces the countdown to 72 cores, but raises the base clock slightly.
Both versions eliminate simultaneous multithreading, which keeps the number of threads equal to the number of cores.
Compared to its predecessor, the KH-40000, the KH-50000 offers enhanced support and memory connectivity.
It will now house 12 channels of DDR5-5200, allowing for up to 3TB of memory, a figure that surpasses the 2TB maximum of the older DDR4 platform.
The chip also introduces 128 PCIe 5.0 lanes and 16 PCIE 4.0 lanes, bandwidth capabilities compared to the previous generation.
While the SATA and USB ports have been trimmed, the move to USB 3.2 Gen 2 modernizes the remaining connections.
The physical footprint measures 72 x 76 mm, closely related to AMD Genoa and Bergamo processors.
It fits into an LGA socket and can scale to 2S and 4S systems, reaching up to 384 cores on the motherboard.
ZPI 5.0 Proprietary Interconnect ZPI 5.0 provides chip-to-chip connectivity aimed at reflecting the scalability offered by AMD's EPYC and Intel Xeon platforms.
The KH-50000 is not intended for gaming or workloads because it is strictly positioned for the server segment.
Here, performance is measured by throughput and scalability rather than by consumer criteria.
However, comparison with the best AMD processor And fastest processors inevitable, although China's domestic priorities may be more important than competition with Western sellers.
What remains uncertain is the TDP, a critical factor that determines how practical this processor will be for real world deployments.
