- Zhaoxin KH-50000 structure suggests lingering shadows of previous AMD ties
- DDR5 reminiscence channels increase capability to 3TB in server environments
- PCIe 5.0 assist delivers a notable leap in information connectivity
Zhaoxin has launched the Kaisheng KH-50000, its newest server processor which adopts a chiplet-based design carefully resembling AMD’s EPYC line.
This similarity raises questions on whether or not the structure displays unbiased innovation or builds closely on earlier hyperlinks between Chinese language companies and AMD know-how.
What makes this release more intriguing is that Zhaoxin has yet to disclose the thermal design power, an omission which leaves industry watchers 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 Centaur Technology’s earlier designs.
The chip uses a chiplet arrangement consisting of twelve compute dies grouped around a large I/O die, creating a total of 96 cores and 384MB of L3 cache.
A second model cuts the count down to 72 cores but raises the base clock slightly.
Both versions exclude simultaneous multithreading, which keeps the thread count equal to the core count.
Compared to its predecessor, the KH-40000, the KH-50000 offers expanded memory support and connectivity.
It now accommodates 12 channels of DDR5-5200, allowing 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, tripling bandwidth opportunities relative to the previous generation.
While SATA and USB ports were trimmed, the shift to USB 3.2 Gen 2 modernizes the remaining connections.
The physical footprint measures 72 x 76 mm, aligning closely with AMD’s Genoa and Bergamo processors.
It fits an LGA socket and can scale into 2S and 4S systems, reaching up to 384 cores on a single motherboard.
Zhaoxin’s proprietary ZPI 5.0 interconnect provides communication between chips, aiming to mirror the scalability offered by AMD EPYC and Intel Xeon platforms.
The KH-50000 is just not designed for gaming or desktop workloads as a result of it’s strictly positioned for the server phase.
Right here, efficiency is measured in throughput and scalability fairly than client benchmarks.
Nevertheless, comparability to one of the best AMD processor and the fastest CPUs is inevitable, though China’s home priorities could matter greater than competing with Western distributors.
What stays unsure is the TDP, a vital issue that determines how sensible this processor will likely be for real-world deployments.
