According to the comparison of core CPU specifications, Kirin 980 has been significantly upgraded in terms of manufacturing process, transistor number, CPU (main frequency/cache), GPU, baseband version, 5G network support, etc. It can be said that the comprehensive performance has been comprehensively upgraded. Let's make a specific comparison and analysis below.
1. Different manufacturing processes
The previous generation Kirin 970 adopted a 10nm process, while the new generation Kirin 980 was upgraded to a more advanced 7nm, making it the world's first processor adopting a 7nm advanced process.
Generally speaking, the lower the value, the more advanced the process, the lower the power consumption and heat generation of the processor. The advantage of feedback to the mobile phone is that it can improve the life of the mobile phone, while the low heat generation can reduce the heat generation of the mobile phone in complex environment, for example, the heat generation of large-scale games will be better controlled.
2. Different CPUs
The previous generation Kirin 970 used A73+A53+NPU and 2M L2 cache specification. The new generation Kirin 980 starts with A76+A55+ dual NPU, 128kB L2 cache +4MB L3 cache, which significantly improves the CPU performance.
Compared with Kirin 970, Kirin 980 has a great upgrade in CPU performance. At the same time, the four A76 cores also divide themselves into two high frequency and two lower frequency, so as to achieve a more balanced energy efficiency ratio without wasting performance and reducing power consumption.
3. GPUs are different
Mali-G72 MP12 12 core design built in the previous generation Kirin 970, with the main frequency of 746Mhz. The new generation Kirin 980 is built with Mali-G76 10 core design, and its main frequency is 720Mhz.
On the surface, the number of cores and frequency of Kirin 980 have been reduced, but in fact it uses Mali-G76 with a new generation of more advanced architecture, and its performance is obviously stronger than G72. According to Huawei's official data, its image performance has been improved up to 46%.
4. Different baseband
The baseband version of the new generation Kirin 980 is LTE Cat.21/18, which is a higher level than Cat.18/13 of Kirin 970. The highest speed of Kirin 980 mobile network reaches 1.4Gbps, which is the fastest in the whole network at present. It supports 4x4 MIMO, three 20Hz carrier aggregation and 256-QAM.
In addition, as the 5G network will be put into commercial use obviously, Kirin 980 supports the plug-in Ba Long 5000 baseband to support the 5G network. The previous generation Kirin 970 does not support 5G network, even if the baseband is plugged in.
5. Other differences
5.1、NPU
Compared with Kirin 970, Kirin 980' s independent NPU has also been upgraded. It is equipped with two NPU units, which has stronger computing power, supports AI scenes such as face recognition, object recognition, object detection, image segmentation, intelligent translation, etc., and has higher precision deep network and better real-time performance.
5.2. Memory support
Kirin 980, like Kirin 970, supports LPDDR4X memory, but Kirin 980 supports the highest LPDDR4X 2133Mhz high-frequency memory with a bandwidth of 34.1GB/s, which is improved compared with Kirin 970.
As for the memory, it remains unchanged from Kirin 970, and still supports UFS 2.1.
5.3. Video decoding
For video decoding, Kirin 980 is equipped with a new fourth-generation ISP, and it is a dual-unit configuration, which claims to increase the decoding speed by 46% compared with Kirin 970. It also supports 4K60fps video decoding and 4K30fps video coding.
Generally speaking, there is a big gap between Kirin 970 and Kirin 980, and there is a gap in all directions. It can be said that the comprehensive performance of Kirin 980 is obviously improved compared with Kirin 970. From the running score of Antu exposed by the Internet, Antu is expected to exceed 300,000 points, which is stronger than Snapdragon 845. Compared with Kirin 970 mobile phone with Antu running score of about 200,000 points, its performance is greatly improved.
