'''Kirin 980''' is a {{arch|64}} high-performance mobile [[ARM]] [[LTE]] SoC designed by [[HiSilicon]] and introduced in late 2018. Fabricated on TSMC's [[7 nm process]], the 980 incorporates four [[big cores|big]] {{armh|Cortex-A76|l=arch}} cores operating at up to 2.6 GHz along with four [[little cores|little]] {{armh|Cortex-A55|l=arch}} cores operating at up to 1.8 GHz. This SoC has an LTE modem supporting 1.4 Gbps download (Cat21), incorporates an ARM {{armh|Mali-G76}}, and supports LPDDR4X-4266 memory.

== Overview ==
Introduced at the 2018 IFA, the overall core organization has changed from the {{\\|970|Kirin 970}} which was introduced the previous year. The 980 features two high-performance [[big cores|big]] {{armh|Cortex-A76|l=arch}} core operating at 2.6 GHz, 2 medium-performance [[big cores|big]] {{armh|Cortex-A76|l=arch}} operating at 1.92 GHz, and four [[little cores|little]] {{armh|Cortex-A55|l=arch}} cores operating at 1.8 GHz. Compared to the {{\\|970|970}}, the 980 features 40% power efficiency and 62.5% smaller [[die area]] due to the [[process shrink]]. The 980 ballooned to over 25% more transistors from 5.5 billion in the {{\\|970}} to 6.9 billion. The 980 adds many enhancements, including a more powerful {{armh|Mali G76}} GPU and incorporates a new dual-[[neural processor]] designed for [[AI]] acceleration. The 980 has two improved [[image signal processor|ISP]]s and a more powerful LTE modem supporting up to [[User Equipment]] (UE) category 21 capable of reaching a maximum downlink of 1.4 Gbps.
