HiSilicon Kirin 935 vs Unisoc SC7731E

VS
The HiSilicon Kirin 935 and the Unisoc SC7731E are two processors with different specifications.

Starting with the HiSilicon Kirin 935, it features an architecture of 4x 2.2 GHz Cortex-A53 and 4x 1.5 GHz Cortex-A53 cores. With a total of 8 cores, this processor offers a powerful performance for multitasking and running demanding applications. The instruction set used is ARMv8-A, which ensures compatibility with the latest software and technologies. The lithography of 28 nm indicates its manufacturing process, which may not be as efficient as newer processors with smaller lithography sizes. However, it still delivers decent performance. The number of transistors is 1000 million, suggesting a good level of hardware integration. The TDP (Thermal Design Power) is 7 Watts, indicating moderate power consumption.

On the other hand, the Unisoc SC7731E has an architecture of 4x 1.3 GHz Cortex-A7 cores. With only 4 cores, this processor may not provide as much processing power as the Kirin 935. The instruction set used is ARMv7-A, which is slightly older than the Kirin 935's ARMv8-A. The lithography size is 28 nm, similar to the Kirin 935, suggesting a comparable manufacturing process. The TDP is also 7 Watts, indicating similar power consumption.

In conclusion, the HiSilicon Kirin 935 offers a more advanced architecture and twice as many cores compared to the Unisoc SC7731E. It also utilizes the newer ARMv8-A instruction set for better software compatibility. However, both processors share the same lithography size and TDP, suggesting they may have similar power consumption levels. Ultimately, the Kirin 935 is likely to deliver better performance and multitasking capabilities compared to the SC7731E.
