China's Zhaoxin KH-50000 CPU has been taped out. This CPU has 96 cores and its IPC is 30% higher than that of KX-7000, reaching the level of Skylake.

KX-7000/8 detail by china tester 8-Core CCD die size ≈ 78.5mm2 IOD die size ≈ 152mm2. not boost all cores 3.2GHz single core 3.6GHz boost all cores boost 3.6GHz single core boost 3.8GHz after some day maybe reach 4GHz

Well, maybe it is confirmed that Zhaoxin has a better architecture, the zx-f/cns consumes 140W at 2.5GHz avx, and at 2.2GHz, only 65W.

CHA/Ncore may no longer be available, cns has more possibilities to be attacked by Spectre than yongfeng

According to some rumors, KX-7000 is manufactured using a variety of different process combinations, possibly SMIC N+2 / TSMC 6nm / HLMC 14nm / TSMC 16nm. KH-50000 same that.

What makes many people unbelievable is that zx-f/cns is not completely designed by Centaur, and zx-g/yongfeng is not designed by Centaur either. zx-h/Century Avenue is based on Yongfeng micro-architecture. Yongfeng's vector unit width is 128 bits. zx-f/cns is 256 bits. zx-f/cns, in the...

Zhaoxin’s next-generation server CPU is KH-50000, which will be launched next year

There was an error in the introduction of the previous test. The KX 7000 was not at the 3.7GHz frequency, but at a higher frequency. The KX7000 is no ordinary KX-7000 processor, but an engineering sample with more options. The Best score in 4GHz and more, use GCC 14, may be Overclocking...

Yes, KX-7000 is based on yongfeng, it may be a modification of yongfeng. In recent years, Zhaoxin has thoroughly understood the design of the CPU by rewriting important modules, iterating Centaur's CNS and the old yongfeng architecture, and many modules in the pipeline have been implemented with...

Some Chinese OEMs I know have tested the KX-7000. The Zhaoxin KaiXian KX-7000 processor is a complex SOC with various units and pipelines to handle different types of instructions. Introduce KX-7000 architecture in here Decoder Units: Four decoder units.(0,1,2,3) 1-uop instructions can be...
