These two processors because the performance is too close to the controversy, let's see how it is.
First of all, the Kirin 820 uses a 7nm production process, and the Kirin 985 uses the same 7nm EUV production process as the 990, and the 985 is indeed a stronger generation than the 820 in terms of production process.
Secondly, it is the CPU and GPU, the Kirin 820CPU includes a high-performance large core A76 2.36GHz, three energy-efficient medium core A76 2.22GHz, and four energy-efficient small core A55 1.84GHz. The GPU uses the six-core Mali-G57. In terms of this chip, it has improved a lot compared to the previous generation, the CPU has increased by 27% compared to 810, the GPU has increased by 38% compared to 810, and the AI ability has increased by 73%, which can be said to be a very large improvement.
The Kirin 985 can be said to be an improved version of the Kirin 980. The CPU is 1*A76 (2.58GHz) 3*A76 (2.4GHz) 4*A55 (1.84GHz). The GPU is an 8-core Mali-G77 GPU.
In fact, it is not difficult to see from the parameters, Kirin 985 is more comprehensive than Kirin 820, but it is not large. Other functions, whether it is 5g chip or Kirin ISP 5.0, are also roughly the same, and the difference is that NPU985 has one more core.
From the running score, it can be seen that 985 is about 410,000, 820 is about 380,000, and the strength is very strong, but Kirin 985 is indeed above Kirin 820, which is more powerful than Kirin 820.
Kirin 985 good.
Kirin 985 and Kirin 990 5G running score difference of about 10,000, Kirin 990 and Kirin 985 will still have a big gap. Kirin 985 and Kirin 990 comparison summary: Overall, Kirin 985, Kirin 990, 990 5G, Kirin 990 5G performance is the best.
The Kirin 985 processor is better because it is more powerful than the former.
First of all, from the point of view of performance, the former is only 380,000 points, while the latter reached nearly 500,000 points, the latter's performance is more than 20% higher than the former, and the latter's power consumption is more than 25% lower than the former.
