HiSilicon Kirin 985 5G vs Unisoc Tiger T618

The HiSilicon Kirin 985 5G and Unisoc Tiger T618 are both powerful processors, but they differ in several key specifications.

Starting with the CPU cores and architecture, the Kirin 985 5G features a more advanced architecture, including 1x 2.58 GHz Cortex-A76 core, 3x 2.4 GHz Cortex-A76 cores, and 4x 1.84 GHz Cortex-A55 cores. On the other hand, the Tiger T618 has 2x 2.0 GHz Cortex-A75 cores and 6x 2.0 GHz Cortex-A55 cores. While both processors have 8 cores in total, the Kirin 985 5G offers a wider range of performance options with its Cortex-A76 cores.

In terms of instruction set, both processors have ARMv8.2-A, which is the latest version offering improved efficiency and performance.

When it comes to lithography, the Kirin 985 5G has a clear advantage with its 7 nm process. In contrast, the Tiger T618 utilizes a larger 12 nm process. The smaller lithography of the Kirin 985 5G allows for greater power efficiency and thermal management.

In terms of TDP (Thermal Design Power), the Kirin 985 5G has a lower TDP of 6 Watts compared to the Tiger T618's 10 Watts. This means that the Kirin 985 5G is designed to consume less power and generate less heat, which can contribute to longer battery life and better overall system performance.

When it comes to Neural Processing Units (NPU), the Kirin 985 5G utilizes the Ascend D110 Lite + Ascend D100 Tiny with HUAWEI Da Vinci Architecture. On the other hand, the Tiger T618 features its own NPU. Both processors support AI tasks, but the specific capabilities and performance of their NPUs may vary.

In conclusion, the HiSilicon Kirin 985 5G offers a more advanced and power-efficient architecture with a broader performance spectrum compared to the Unisoc Tiger T618. However, the Tiger T618 still provides solid performance and includes its own NPU. The final choice will depend on specific requirements and priorities, such as power efficiency, AI capabilities, and overall system performance.
