Interpretation of Huawei Kirin 9000

Kirin 9000 is the world's first 5G SoC with 5nm process technology, and it is the most advanced technology at present. Kirin 9000 and Apple A 14 adopted this technology. However, like Kirin 990 5G, Kirin 9000 integrates 5G baseband and chip, which can release more space and be more energy efficient than the form of baseband plug-in.

In the small Kirin 9000 chip, the number of transistors has reached 65.438+053 billion, including CPU, GPU, NPU, ISP and communication modem. Although the 5G modem is still the familiar Ba Long 5000, Huawei has optimized it.

Snapdragon 5000 supports the characteristics of dual-carrier aggregation aggregation, and the domestic 5G frequency in China has the most spectrum. The establishment of 5G networks of the three major operators has given Ba Long 5000 a higher space to play. Kirin 9000 supports 200M dual-carrier aggregation polymerization. In the Sub-6G SA network, the theoretical downlink peak rate of Kirin 9000 can reach 4.6Gbps and the uplink peak rate can reach 2.5Gbps, which is twice that of Snapdragon 865+ and A 14.

Of course, this is only a theoretical value, which may change in real life because of the environment. Huawei conducted a field test of delayed live network through China mobile network in Hangzhou, and the results showed that the online rate of Kirin 9000 was 83% in less than 30 ms. This means that mobile phones using Kirin 9000 can have a more stable 5G network.

On the CPU side, Kirin 9000 adopts a three-cluster architecture, namely 1 A77 super-large core (3. 13GHz), 3 A77 large cores (2.54GHz) and 4 A55 small cores. The improvement of GPU is relatively more obvious. The GPU of Kirin 9000 has been upgraded from the previous generation 16-core Mali G76 to the 24-core G78. Compared with Snapdragon 865+, the performance is improved by 52% and the energy efficiency is improved by 50%.

This improvement can improve the overall experience of users playing games, such as clearer and more stable pictures and less power consumption, which also means that Kirin 9000 can let users have more game time.
