Kirin 980 is a 64-bit 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 Cortex-A76 cores operating at up to 2.6 GHz along with four little Cortex-A55 cores operating at up to 1.8 GHz. This chip incorporates an ARM Mali-G76 and LPDDR4X-4266 memory.

Overview

Introduced at the 2018 IFA, the overall core organization has changed from the Kirin 970 which was introduced the previous year. The 970 features two high-performance big Cortex-A76 core operating at 2.6 GHz, 2 medium-performance big Cortex-A76 operating at 1.92 GHz, and four little Cortex-A55 cores operating at 1.8 GHz. Compard to the 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 Mali G76 GPU and incorporates a new dual-neural processor designed for AI acceleration. The 970 has two improved ISPs and a more powerful LTE modem supporting up to User Equipment (UE) category 21 capable of reaching a maximum downlink of 1.4 Gbps.

Memory controller

The Kirin 980 supports 4-channel LPDDR4X up to 2133 MHz. Each channel supports at most two ranks.
