Kunpeng (Hi16xx) is a family of 64-bit ARM multi-core server SoCs designed for Huawei line of enterprise ARM servers.

Overview

Kunpeng, also known as Hi16xx, is a series of 64-bit ARM server microprocessors designed by Huawei. First introduced in 2015, those processors are geared towards highly-threaded or high-throughput applications. Those processors are only found in the HiSilicon evaluation development boards and in a few limited series of Huawei servers. In 2018, with the introduction of the 920 series, Huawei rebranded the series as the Kunpeng.

In late 2018, Huawei announced the 920 series, also known as the Hi1620. Manufactured on TSMC's 7 nm process, those processors are based on the company's custom-designed Taishan v110 ARMv 8.2 cores operating at up to 2.6 GHz. All models support up to eight channels of DDR4 memory and up to four-way SMP.

• ISA: ARMv8.2
• TDP: 100 W - 200 W
• Mem: Octa-channel DDR4-2933 memory
• I/O: x40 PCIe Gen 4, 2x 100GbE, RoCEv2, CCIX, 4x USB 3.0, x16 SAS 3.0, 2x SATA 3.0
