Kirin 820 Details:

5G SoC:

Kirin 820 is the first mid-range 5G chipset, integrating a 5G modem to provide a cost-effective option. It supports both non-standalone and standalone architectures, as well as TDD/FDD full-frequency bands.

With dual-SIM service concurrency enabled by Kirin 820-powered 5G smartphones, consumers are able to play 5G games on one SIM while making VoLTE HD calls and sending SMS messages on the other SIM.

Kirin 820 optimizes 5G communication experience with features including anti-interference capabilities for complex 5G communication environments, an advanced adaptive receiver for high-speed mobile scenarios, and an ability to intelligently select the optimal channel model for high-speed scenarios.

To reduce latency, the SoC achieves the industry-highest 5G network ratio by comprehensively accelerating 5G network searching and handover, and quicken the time for processing large files and videos.

In addition, Kirin 820 supports bandwidth part (BWP) technology, which implements the switching of bandwidth resources with available 5G bandwidths, reducing 5G power consumption and offering a lasting 5G experience.

NPU:

This mid-range adopts Huawei’s in-house Da Vinci NPU, enhancing AI computing by 73% at a lower power consumption compared with its predecessor.

Octa-Core CPU and New GPU:

Kirin 820 features an octa-core CPU with one high-performance big core, three balanced middle cores, and four energy-efficient little cores. The big and middle cores are customized based on Cortex-A76 and the little cores are customized based on Cortex-A55.

Achieving an operating rate of up to 2.36 GHz, this combination improves the overall multi-core performance by 27% compared with the previous generation. The Mali-G57 GPU boosts the performance by 38% and energy efficiency by 39% for a faster and smoother gaming experience.

Kirin 820 has Gaming+ 2.0, which incorporates 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 over 1 million frames of game images for refinements to performance and power consumption scheduling for each frame and in-depth and precise optimization.

Huawei ISP 5.0:

The Huawei-developed ISP 5.0 supports BM3D for professional-level hardware noise reduction and dual-domain video noise reduction, delivering sharp images and videos even in low light environments.
