Still dominate the list! Apple A15's powerful iPhone 14 low-end model continues to be used
Apple's processor has always been the best processor in smart phones, and A15 is the top among them. It will be welcomed by many users when it is launched on September 15, 2021. How about the specific performance of this high-end mobile phone processor? I have compiled the relevant performance score introduction for you, and I hope it can help you!
Still dominate the list! Performance Analysis of Apple A15
Score
According to the score results of Geekbench5, a famous score scoring website, Apple A15 currently has 1724 points for single core and 4625 points for multiple cores. It is now the best in mobile phones. A14Bionic is equipped with a new 16 core Neural Engine, which doubles the number of cores compared with the previous generation, and can process up to 11 trillion operations per second, making this chip's machine learning performance a breakthrough.
Schema Parameters
A15 continues to integrate six core CPUs, including two high-performance large cores, four low-power small cores, 4-5 GPU cores, as well as new display pipelines, video encoders, video decoders, ISPs, doubled system cache, and stronger neural networks.
In terms of CPU, the large core microarchitecture has little change compared with A14, at least the throughput and latency of the back-end remain unchanged.
There are relatively many small kernel changes. For example, the number of integer ALUs has increased from 3 to 4, and the cache subsystem TLB has been upgraded.
The operating frequency of a single large core is up to 3240MHz, which is 242 MHz higher than A14. The parallel operation of two large cores is 3180MHz, which is 290MHz higher. The maximum operation frequency of a small core is 2016MHz, which is 193MHz higher.
The A15 manufacturing process is still TSMC 5nm. It is speculated that it should be an enhanced version of the N5P, which also contributes to the frequency increase.
The system cache has doubled from 16MB on A13/A14 to 32MB, and the large core L2 cache has also increased by half from 8MB to 12MB, which is larger than the total cache of Snapdragon 888 and other SoCs. At the same time, it is the same as Apple M1, but only serves two cores instead of four.
The second level cache of the small core remains at 4MB, but TLB is increased.
CPU test
The CPU part of the test uses the SPEC CPU 2017. In addition to comparing the performance (on the left), it also adds a comparison of power consumption (on the right).
In terms of small cores, compared with the previous generation, the minimum increase is 8.4% (531. deepsjeng_r), and the maximum increase is 46% (520. omnitpp_r). The overall increase is 23%, which means a significant increase of 11.6% in IPC.
The power consumption is basically the same, so the energy efficiency improvement is not as obvious as that of the big core.
The A78 and A55 cores in Snapdragon 888 can't be played at all. For example, compared with the A55, the performance of the A15 small core is 3.5 times higher on average, and the power consumption is only 32% higher, so the energy efficiency exceeds 60%.
GPU test
For the first time, different models of the iPhone 13 are configured with different GPU specifications. The 13 Pro series are all complete with 5 cores, while the 13 mini and 13 have only 4 cores. This test is for 13 and 13 Pro.
In the 3DMark Wild Life test, the peak performance of 13 Pro and 13 Pro is 30% and 14% higher than that of the previous generation respectively, and the peak performance is at least twice that of the competitors.
However, in terms of continuous performance, 13 is higher than 13 Pro.
Game Test
As for the actual game test, it is difficult to completely unify the games on Android and iOS platforms, so it is not easy to directly compare them. Here we take "Genshin Impact" as an example, running the iPhone 13 Pro Max, and the Samsung Galaxy S21 Ultra and Xiaomi 11 Ultra of Snapdragon 888.
Xiaomi 11 Ultra
Samsung S21 Ultra
The power consumption of the Snapdragon 888 of the S21 Ultra has been stable at 3.5W, while that of the Xiaomi 11 is 5-6W, significantly higher.
The iOS version has higher resolution and finer image quality.
The above is an introduction to the performance of Apple A15. This processor is excellent in all aspects. It has brought users a good experience in both running and testing. Those who like this processor can try this phone!
