Zhaoxin’s Kaisheng KH-50000 steps into modern server territory with a 96-core chiplet design, 12-channel DDR5, and 128 lanes of PCIe 5.0. On paper, it mirrors the platform basics everyone expects in 2025—the questions are perf/W, software maturity, and supply.
The flagship KH-50000 is a 96-core part built from twelve 8-core chiplets around a central I/O die, for a quoted 384MB L3. Zhaoxin also plans a 72-core SKU. Both reportedly skip SMT. Platform specs include 12-channel DDR5-5200 (up to multi-terabyte capacities), 128 PCIe 5.0 lanes (+16 PCIe 4.0), and 4-socket scaling—meaning up to 384 cores per motherboard. Clocks cited top out around 3.0 GHz boost, but there’s no official TDP yet.
Specs are table stakes. Whether this rivals EPYC in the real world will hinge on compiler/toolchain health, virtualization stacks, security features, binning, and power. If volume and perf/W aren’t there, KH-50000 risks being a domestic procurement checkbox rather than an EPYC alternative.
Background on why this leap is feasible: chiplets let you stitch moderate-sized dies on older nodes into big CPUs. We’ve covered the approach in what is chiplet architecture and why DDR5 memory channels matter for bandwidth-bound workloads.
