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



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 were only found in the HiSilicon evaluation development boards and in a few limited series of Huawei servers. Huawei expanded their server offerings in 2018 and 2019 with the TaiShan line of servers. In early 2019, with the introduction of the 920 series, Huawei rebranded the series as the Kunpeng.

Hi1620 on exhibit.

In late 2018, Huawei announced the Kunpeng 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.

  • Proc: 7 nm process
  • ISA: ARMv8.2
  • TDP: 100 W - 200 W
  • Mem: Octa-channel DDR4-2933 memory
  • I/O: x40 PCIe Gen 4 with CCIX support, 2x 100GbE, RoCEv2, 4x USB 3.0, x16 SAS 3.0, 2x SATA 3.0

930 Series[edit]

Kunpeng 930 Roadmap

Next-generation SoCs are the Hi1630 which are branded as Kunpeng 930 series. Those chips are expected to feature a higher-performance core with higher frequencies, simultaneous multithreading support, and Arm’s Scalable Vector Extension (SVE) extension. Those chips will are also planned to move to DDR5 memory.

950 Series[edit]

The Kunpeng 950 series will be the follow-up to the 930 and are planned for the 2023 timeframe.
