HiSilicon Kirin 820 5G vs HiSilicon Kirin 950

When comparing the HiSilicon Kirin 820 5G and the HiSilicon Kirin 950 processors based on their specifications, several key differences can be identified.

Starting with the CPU architecture, the Kirin 820 5G features a 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 950 is equipped with 4x 2.4 GHz Cortex-A72 cores and 4x 1.8 GHz Cortex-A53 cores. This suggests that the Kirin 820 5G has a more advanced and diverse CPU architecture compared to the Kirin 950.

Another notable difference is the lithography process. The Kirin 820 5G utilizes a more advanced 7 nm lithography process, while the Kirin 950 uses a 16 nm lithography process. Generally, a smaller lithography process allows for more transistors and better power efficiency, making the Kirin 820 5G potentially more efficient in terms of power consumption.

Speaking of power consumption, the thermal design power (TDP) of the Kirin 820 5G is listed as 6 Watts, whereas the Kirin 950 has a TDP of 5 Watts. This suggests that the Kirin 950 might be more power-efficient than the Kirin 820 5G, although the difference is relatively small.

In terms of instruction set, the Kirin 820 5G adopts ARMv8.2-A, while the Kirin 950 uses ARMv8-A. The Kirin 820 5G's ARMv8.2-A instruction set offers architectural enhancements over the Kirin 950's ARMv8-A instruction set, potentially resulting in improved performance and efficiency.

Lastly, the Kirin 820 5G features the Ascend D110 Lite neural processing and HUAWEI Da Vinci architecture for neural processing tasks, whereas the Kirin 950 does not mention any specific neural processing capabilities.

Overall, the HiSilicon Kirin 820 5G appears to be more advanced in terms of CPU architecture, lithography process, and instruction set compared to the HiSilicon Kirin 950. However, the Kirin 950 may have a slight advantage in terms of power efficiency. The inclusion of specific neural processing capabilities is also a notable difference between the two processors.
