Compared with the current industry standard 10 nm process technology, the TSMC 7 nm manufacturing process used to create the Kirin 980 improves chipset performance by 13%, energy efficiency by 25%, and transistor density by 1.6 times, enhancing both performance and energy efficiency.

This process upgrade is accompanied by a subsequent evolution in the design of 7 nm chipsets. Physically, silicon-based semiconductors can only be reduced to 7 nm in size before the electrons end up flowing uncontrollably from one gate to the next. To push right up to this 7 nm limit, the Kirin 980 had to be able to address the limitations of current semiconductor technology and the three-dimensional resistance and capacitance of transistors.

The Kirin 970 is the first to put dual-card dual-4G dual-VoLTE technology into commercial use. This feature enables both the primary SIM card and the secondary SIM card on a smartphone to support 4G VoLTE calls and provide the same HD voice calls and video calls.

To address these issues, Huawei's chipset team has started the basic research on the new 7 nm process three years in advance, and gathered the advanced IP and system design capabilities of the industry and Huawei to effectively solve the problem of 7 nm mass production. With a heterogeneous architecture for system convergence and optimization based on the CPU, GPU, NPU, ISP, and DDR, Kirin 980 integrates 6.9 billion transistors in less than 1 square centimeter. The stronger CPU, GPU, DDR, smarter NPU, better ISP, and faster modem bring the chipset an excellent energy efficiency ratio to achieve comprehensive leadership in performance and energy efficiency.

To enable the latest 7 nm process to provide mobiles users with stable and reliable premium experience, Kirin 980 has undergone a large number of reliability tests on the basis of implementation of high performance and high energy efficiency. The comprehensive verification from the chipset to the entire system provides the most reliable technical assurance for mobile phone users.

In addition to the adaptation and optimization of terminal services on the CPU core, the CPU scheduling algorithm and bus are thoroughly designed to ensure that the Kirin CPU subsystem meet the increased user response and battery life requirements.

The Kirin CPU subsystem uses an intelligent flex-scheduling mechanism that creates a 3-level energy efficiency architecture consisting of two super-big cores based on Cortex-A76, two big cores based on Cortex-A76, and four little cores based on Cortex-A55. Compared with the traditional big.LITTLE design, the 3-level energy efficiency architecture provides more precise scheduling layers. This not only allows the CPU to adapt flexibly in heavy-load, medium-load, and light-load scenarios, but also greatly reduces the CPU power consumption in actual integrated service scenarios.

The Kirin 980 is also the first in the industry to put the Mali-G76 GPU into commercial use. Compared with its predecessors, the Mali-G76 GPU improves performance by 46% and energy efficiency by 178%. This GPU can work seamlessly with Huawei’s innovative AI frequency modulation scheduling technology, which predicts task load by learning frame rates, smoothness, and touchscreen input changes in real time and dynamically and intelligently detects performance bottlenecks. Especially in gaming scenarios, this scheduling technology improves each frame’s load prediction accuracy by more than 30% when compared with traditional prediction methods. This effectively improves average frame rates and greatly reduces game jitters and freezes, making mobile games play more smoothly. Take the heavy-load 3D game NBA2K18 as an example, which has a max frame rate is 60 fps. The Kirin 980's max frame rate is just below 60 fps, while competitors cannot even come close. This provides a gaming experience far beyond the industry average and allowing users to play heavy-load games smoothly and seamlessly on their mobile phones.
