Huawei develops new ARM-based server CPU
Kunpeng 920 processor is best performing ARM process, says Huawei
Huawei has announced a new ARM-based server CPU, which it says is the highest performing ARM based processor on the market.
The new Kunpeng 920 processor was designed by Huawei based on ARMv8 architecture license.
The new CPU is designed to boost the development of computing in big data, distributed storage, and ARM-native application scenarios. The processor is built on 7nm wafer, and significantly improves processor performance by optimizing branch prediction algorithms, increasing the number of OP units, and improving the memory subsystem architecture. At typical frequency, the Kunpeng 920 CPU scores over 930 in the SPECint Benchmarks test, which is 25% higher than the industry benchmark.
At the same time, power efficiency is 30% better than that offered by industry counterparts. Kunpeng 920 provides much higher computing performance for data centers while slashing power consumption.
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%. 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 has also released three new servers in its TaiShan range which use the Kunpeng 920, with specific models for storage, high density deployment and balanced usage. The TaiShan servers are built for big data, distributed storage, and ARM-native application scenarios. The ARM architecture is best suited for these scenarios with advantages in many-core and performance per watt. TaiShan will enable computing platforms with high performance and low power consumption for enterprises.
