HiSilicon Kirin 935 vs HiSilicon Kirin 955

The HiSilicon Kirin 935 and HiSilicon Kirin 955 are both processors used in mobile devices like smartphones and tablets. While they have some similarities, they also have several key differences in terms of their specifications.

One major difference between the two processors is their CPU architecture. The HiSilicon Kirin 935 has a CPU architecture comprised of 4x 2.2 GHz Cortex-A53 cores and 4x 1.5 GHz Cortex-A53 cores. On the other hand, the HiSilicon Kirin 955 has a CPU architecture composed of 4x 2.5 GHz Cortex-A72 cores and 4x 1.8 GHz Cortex-A53 cores. This means that the Kirin 955 has faster and more powerful CPU cores in comparison to the Kirin 935.

Another significant difference between the two processors is their lithography. The HiSilicon Kirin 935 has a lithography of 28 nm, while the Kirin 955 has a lithography of 16 nm. A smaller lithography generally translates to improved power efficiency and performance.

The number of transistors is also different between the two processors. The Kirin 935 has 1000 million transistors, whereas the Kirin 955 has 2000 million transistors. This suggests that the Kirin 955 has a higher transistor count, which can lead to better overall performance and functionality.

One final difference to note is the thermal design power (TDP) of the processors. The Kirin 935 has a TDP of 7 Watts, while the Kirin 955 has a lower TDP of 5 Watts. A lower TDP typically indicates better power efficiency, which can contribute to longer battery life and cooler operation.

In summary, the HiSilicon Kirin 955 offers several improvements over the Kirin 935. With a more powerful CPU architecture, smaller lithography, higher transistor count, and lower TDP, the Kirin 955 generally provides better performance and power efficiency.
