Chinese import substitution: Zhaoxin plans to release 7nm processors with support for PCIe 4.0 and DDR5 in 2021

KX-7000 processors expected to have new DirectX 12 compatible iGPU.
Citing a WikiChip Fuse, the source said that Chinese processor maker Zhaoxin outlined its next-generation KaiXian and KaiSheng processors. KaiXian processors are for consumer systems, and KaiSheng processors are for servers. These are the two main lines of Zhaoxin processors.

The modern processors of the KaiXian KX-6000 and KaiSheng KH-30000 series are produced by TSMC using a 16-nanometer process technology. However, by 2021, the Chinese company expects to achieve parity with Intel and AMD in terms of technology.

KaiXian KX-6000 processors are built on the LuJiaZui microarchitecture, have up to eight cores and operate at frequencies up to 3 GHz. According to unconfirmed reports, the basis of the KX-7000 processors will serve as a new architecture. These processors will be designed for release at 7 nm standards. The transition from 16 nm to 7 nm will increase the frequency, which, coupled with the new microarchitecture, will reduce the performance lag from Intel and AMD processors.

It is expected that the KX-7000 processors will have a new iGPU compatible with DirectX 12, as well as a PCIe 4.0 root system and a DDR5 memory controller.

KH-30000 server processors now also use the LuJiaZui microarchitecture. These processors have up to eight cores operating at frequencies up to 2.7 GHz. The KH-30000 will be followed by the KH-40,000 series. These processors will also be 16-nanometer, but their basis will be a new microarchitecture, and the number of cores will be increased to 32. In addition, it is assumed that the KH-40000 processors will support dual-processor configurations, DDR4 memory and PCIe 3.0 interface.
