Kirin 985 5G – A Faster, Better, 5G supported Kirin 980?

Starting with the process, Kirin 985 features the TSMC’s 7nm LPP FinFET+ process. Similar to the Kirin 820, it’s N7P, DUV-based. In terms of CPU configuration, Kirin 985 5G has a tri-cluster design with the octa-core design (1+3+4). The high-performance core is  Cortex A76 core running at a speed of 2.58 GHz. There are three Cortex A76 cores at a speed of 2.4GHz clock speed acting as mid-performance clusters. Last but not least, we have four power-efficient Cortex A55 cores at a speed of 1.84GHz for less demanding tasks.

Connectivity

Kirin 985 highlights its integrated single-chip 5G baseband solution without a plug-in. It supports 2G / 3G / 4G / 5G network standard and NSA / SA 5G dual-mode. The theoretical maximum download rate is 1277 Mbps and the upload rate is 173 Mbps. Compared to the combination of Snapdragon 865 + Snapdragon X55 it is about 40% and 75% faster, respectively.

Since the capacity isn’t that much, the energy efficiency of Kirin 985 5G appears to be high. According to the officials, the power consumption under 5G heavy load and light load scenarios are only 504 mA and 291 mA, respectively, and the energy efficiency ratio is about 1.5 times that of Snapdragon 865 + Snapdragon X55.
