Zhaoxin (Shanghai Zhaoxin Semiconductor Co., Ltd. Chinese: 兆芯; pinyin: Zhào xīn) is a fabless semiconductor company, created in 2013 as a joint venture between VIA Technologies and the Shanghai Municipal Government. The company creates x86 compatible CPUs. The term Zhào xīn means trillion core. The processors are created mainly for the Chinese market: the venture is an attempt to reduce the Chinese dependence on foreign technology.
The architecture of the ZX family of processors is a continuation of VIA's Centaur Technology x86-64 Isaiah design. The ZX-A and ZX-B are based on VIA Nano X2 C4350AL. The ZX-B is identical to the ZX-A, except that it is manufactured by Shanghai Huali Microelectronics Corporation. The ZX-C is based on the VIA QuadCore-E & Eden X4.
Zhaoxin came to the North American & European technology press' attention with the ZX-D processor, and its plan for future products, in late 2017/early 2018. Changes to the ZX-D include the integration of the northbridge like modern x86 designs, as well as additions of Chinese cryptographic functions. The ZX series also has integrated GPU technology from VIA's S3 Graphics. The ZX-D is noted to have roughly the performance of the Intel Silvermont (Avoton) processors.
The KX-6000 (formerly ZX-E) system on a chip was demonstrated to press in September 2018. The chip has an integrated DirectX 11.1 compatible GPU. The chip is reported to have a 50% performance increase over the KX-5000, and comparable performance to a 7th generation Intel i5 core processor from 2016.
