HiSilicon Kirin 820 5G vs HiSilicon Kirin 955

The HiSilicon Kirin 820 5G and HiSilicon Kirin 955 are two processors offering different specifications and features. Let's compare them based on their specifications.

Starting with the HiSilicon Kirin 820 5G, it features a more advanced architecture compared to the Kirin 955. This includes 1x 2.36 GHz Cortex-A76 core, 3x 2.22 GHz Cortex-A76 cores, and 4x 1.84 GHz Cortex-A55 cores. In contrast, the Kirin 955 consists of 4x 2.5 GHz Cortex-A72 cores and 4x 1.8 GHz Cortex-A53 cores.

The number of cores is the same for both processors, being 8, but the Kirin 820 5G provides a more diverse and efficient mix of cores for better performance across various tasks. It also offers the ARMv8.2-A instruction set, while the Kirin 955 utilizes ARMv8-A instruction set.

In terms of manufacturing technology, the Kirin 820 5G has an advantage with its 7 nm lithography, which allows for better power efficiency and heat management. The Kirin 955, on the other hand, has a 16 nm lithography, which is not as advanced.

The Neural Processing capabilities of the two processors also vary. The Kirin 820 5G integrates Ascend D110 Lite and HUAWEI Da Vinci Architecture, providing improved AI performance. The Kirin 955 does not mention any specific neural processing features.

In terms of power consumption, the Kirin 955 has a slightly lower TDP (thermal design power) of 5 Watts compared to the Kirin 820 5G with a TDP of 6 Watts. Lower TDP generally results in better energy efficiency.

To summarize, the HiSilicon Kirin 820 5G stands out with its more advanced architecture, diverse core configuration, improved neural processing capabilities, and better power efficiency thanks to its 7 nm lithography. However, the Kirin 955 still offers decent performance with its combination of Cortex-A72 and Cortex-A53 cores.
