China efforts to become independent from the West with regard to the required enterprise hardware for the server segment continue to bear fruit with the Zhaoxin KH-50000: 96 cores, a huge L3 cache and PCIe 5.0 are offered.

The Zhaoxin KH-50000: 96 processor cores with high IPC, a huge L3 cache of up to 384 MiBytes as well as 128 × PCIe 5.0 and DDR5 on a powerful memory interface with 12 channels are offered. The Chinese manufacturer is targeting the still emerging segment of AI servers.

Mega CPU Zhaoxin KH-5000 Specs Comparison

As part of the Shanghai World Expo 2025, the Chinese company Zhaoxin has officially announced its KH-50000 server processors and also named the first technical specifications. In direct comparison to the previous generation, far-reaching improvements should have been achieved, according to reports from China.

Zhaxoin KH-40000		Zhaxoin KH-50000
Processor cores	up to 32 processor cores	→ → →	up to 96 processor cores
Clock frequencies	up to 2.5 GHz boost clock	→ → →	up to 3.0 GHz boost clock
L3 cache	up to 64 MiByte	→ → →	up to 384 MiByte
memory	8-channel DDR4	→ → →	12-channel DDR5
PCIe	128 × PCIe 4.0	→ → →	128 × PCIe 5.0

according to the manufacturer, the IPC increases by ~ 30 percent.

In addition to the modernized and expanded memory interface, which can now connect up to 6 TB DDR5-RDIMM with ECC support via 12 memory channels, the in-house Interconnect ZPI has now been upgraded from version 3.0 to version 5.0. This allows up to four of the CPUs to be combined with up to 384 cores and used on a quad-socket mainboard.

The new server CPUs are expected to reach the Chinese market later this year and represent another declaration of China's independence in this so important segment. In addition, the manufacturer announced that it will soon be presenting the successors of its current desktop CPUs of the Zhaoxin KX-7000 series, which will also receive an NPU in addition to PCIe 5.0.
