Huawei announces ARM-based CPU

Huawei has announced a 7nm ARM-based CPU, Kunpeng 920, aimed at server applications including big data, distributed storage, and HPC and AI.

‘Currently, the diversity of applications and data is driving heterogeneous computing requirements. Huawei has long partnered with Intel to make great achievements. Together we have contributed to the development of the ICT industry. Huawei and Intel will continue our long-term strategic partnerships and continue to innovate together,’ commented William Xu, director of the board and chief strategy marketing officer at Huawei.

Huawei claims that the Kunpeng 920 is the industry's highest-performance ARM-based server CPU. Based on a 7nm process fabrication process, the CPU was independently designed by Huawei based on ARMv8 architecture license. The company notes that performance is increased by optimising branch prediction algorithms, increasing the number of OP units, and improving the memory subsystem architecture. Huawei also announced that the Kunpeng 920 CPU scores over 930 in the SPECint Benchmarks test, which is 25 per cent higher than the industry benchmark. At the same time, power efficiency up to 30 per cent better than that offered by industry counterparts.

‘At the same time, the ARM industry is seeing a new development opportunity. The Kunpeng 920 CPU and TaiShan servers newly released by Huawei are primarily used in big data, distributed storage, and ARM-native applications. We will work with global partners in the spirit of openness, collaboration, and shared success to drive the development of the ARM ecosystem and expand the computing space, and embrace a diversified computing era’ added Xu

Kunpeng 920 integrates 64 cores at a frequency of 2.6 GHz. This chipset integrates 8-channel DDR4, and memory bandwidth exceeds incumbent offerings by 46 per cent. System integration is also increased significantly through the two 100G RoCE ports. Kunpeng 920 supports PCIe 4.0 and CCIX interfaces and provides 640 Gbps total bandwidth. In addition, the single-slot speed is twice that of the incumbent offering, effectively improving the performance of storage and various accelerators.

Huawei is working with Arm to continuously promote industry cooperation in terms of hardware, software, and applications. Huawei has been working with industry organizations such as Green Computing Consortium (GCC), Linaro, and Open Edge and HPC Initiative (OEHI) to build an open, collaborative industry ecosystem, alongside partners such as Hortonworks, Microsoft, Oracle, SAP, SUSE, Ubuntu, and China Standard Software.

To develop hardware Huawei is working with Linaro which aims to accelerate the development of Arm technology. Huawei is also a Platinum member of the OpenStack Foundation and a founding member of Cloud Native Computing Foundation (CNCF) to develop software.

‘Today, with Kunpeng 920, we are entering an era of diversified computing embodied by multiple cores and heterogeneity. Huawei has invested patiently and intensively in computing innovation to continuously make breakthroughs. We will work with our customers and partners to build a fully connected, intelligent world,’ noted Xu.
