Kirin 985 Details:

5G SoC:

Kirin 985 achieves leading 5G speed and supports NSA and SA architecture and TDD/FDD full spectrum bands. It also supports service concurrency for dual cards on 5G phones. Users can play games using one 5G mobile data over one SIM card, while still using the other SIM to receive VoLTE HD voice calls and handle messaging at the same time.

To provide seamlessly 5G experiences, the Kirin 895 5G comes with anti-jamming capabilities for complex 5G communication environments, the advanced adaptive receiver based on machine learning for high-speed mobile scenarios.

To reduce latency, Kirin 985 accelerates 5G network searching and handover. Achieving the best 5G occupation ratio to ensure ultra-low latency.

In addition, Kirin 985 supports bandwidth part (BWP) technology, which implements the flexible switching of bandwidth resources with available 5G bandwidths. Reducing 5G power consumption and offering a lasting 5G experience.

NPU:

Kirin 985 adopts Da Vinci NPU architecture, improving AI performance by 173% compared to the predecessor.

The AI power of Kirin 985 improves photographs by providing smarter AI shooting, solves common issues.  The new AI RAW technology significantly improves image quality. It enriches image detail while reducing noise, and boosts the image’s dynamic range performance.

Based on the AI portrait segmentation capability, Kirin 985 effectively removes image distortions at the edges of group photos and performs real-time AI correction on the edges of images to achieve the desired effects.

Kirin ISP 5.0:

The Huawei-developed Kirin ISP 5.0 improves both pixel throughput and energy efficiency by 15% over the previous generation. In addition to the AI RAW technology, Kirin ISP 5.0 supports BM3D for image noise reduction and dual-domain video noise reduction. This improves noise reduction performance for images and videos by 30% and 20%, respectively.

CPU and GPU:

Kirin 985 has a new CPU architecture including one big core (Cortex-A76 Based), three middle cores (Cortex-A76 Based), and four little cores (Cortex-A55). This combination achieves optimum performance and higher energy efficiency.

For the first-ever, Huawei has used a new 8-core Mali-G77 GPU in its chipset starting Kirin 985.  The new GPU greatly improves performance and energy efficiency and allows for a faster and smoother gaming experience.

To help achieve this, Kirin 985 supports Kirin Gaming+ 2.0, which uses the newly updated AI frequency modulation scheduling technology.

The technology fuses GPU scheduling into the CPU and DDR system frequency modulation scheduling and adds gaming-associated thread optimization technologies to dynamically detect performance bottlenecks.

Moreover, Kirin Gaming+ 2.0 builds a precise performance and power consumption model by learning from over 1 million frames of game images, refining performance and power consumption scheduling for each frame, and achieving in-depth and precise optimization.
