The wave of new phones at the end of this year is earlier than last year, and you can see new phones equipped with the fourth-generation Snapdragon 8 and Dimensity 9400 as soon as after the National Day.

At this time, the question is, what is the performance of this wave of new machines?

At present, it is probably certain that the Dimensity 9400 will choose the CPU and GPU of ARM's new generation of public version, which are Cortex-X925 CPU and Immortalis G925 GPU, which are iterations of the Cortex-X4 and Immortalis G720 used in the Dimensity 9300.

ARM said that this time, in order to highlight the significant increase in CPU, the naming convention of Cortex-X was specifically changed. Officially, the Cortex-X925 delivers a 36% increase in single-core performance over the previous generation X4's Geekbench single-core performance, and thanks to 3MB of private L2 cache, the performance of AI workloads is improved by 41%.

According to the results of our third-generation Snapdragon 8, Dimensity 9300, and A17 Pro cross-test last time, although the comprehensive performance of the Dimensity 9300 exceeds that of the A17 Pro, it is only slightly inferior to Apple in single-core performance. Since ARM separately lists the single-core performance for publicity, it means that the single-core performance of the Dimensity 9400 will be significantly improved this time.

The GPU part is the Immortalis G925 GPU, which Arm claims is the "most powerful and efficient graphics processor" to date. Compared to the previous generation, the G720 delivers 37% faster graphics applications, 52% better ray tracing performance for complex objects, and 34% faster AI and ML workloads, while reducing power consumption by 30%.

According to the information currently exposed, the Dimensity 9400 is still an all-large core architecture, coupled with ARM's progress in performance and energy efficiency, it is expected that it will perform well in terms of performance and energy efficiency. The vivo X200 series and the OPPO Find X8 series are likely to be the first phones to use the Dimensity 9400.

The fourth-generation Snapdragon 8 has changed a lot, because this time it is very likely to use Qualcomm's self-developed CPU and GPU architecture, which was previously the public version of the CPU + self-developed GPU, such as the third-generation Snapdragon 8 is this combination. It was previously reported that Qualcomm has revised the design and will increase the main frequency to 4.26GHz.

This is a very high frequency, and for comparison, the third-generation Snapdragon 8 commonly used in flagship phones is 3.3GHz. Higher clock speeds will bring more extreme performance to maintain the performance advantage over Apple's A-series chips since last year. However, with such a high frequency, people are very concerned about its power consumption and energy efficiency level.

As for the iterative chip of the A17 Pro, let's call it "A18 Pro", there is not much information about it at the moment, but we can find a little information from Apple's latest release of the M4.

The M4 uses N3E, an improved 3nm process technology, and its performance is the largest performance upgrade since the launch of the M1, but the energy efficiency has not changed much compared to the M3.

Therefore, the N3E process may not bring any energy efficiency upgrades to the A18 Pro, and the feedback to the use of the mobile phone is the power consumption of the new machine, and the battery life may not change much compared with the iPhone 15 Pro series. Let's wait to see if Apple will upgrade the A18 Pro's chip architecture to achieve better performance and energy efficiency.

In addition to the above three chips, Kirin Core will also have iterations at the end of the year, which will be launched by the Mate70 series. Huawei Pura70 Ultra uses Kirin 9010, bringing the first real super-large core of the Kirin chip, and the actual performance improvement at that time is very exciting.
