The iPhone 14 may also use the A15 chip. Will its performance be sufficient?

In the near future, as the launch of the new iPhone 14 series is getting closer, there are more and more revelations about the iPhone 14 series. In the relevant breaking information, it is pointed out that the iPhone 14 will still use the same Apple A15 series chips as the previous generation iPhone 13 or iPhone 13 Pro series, but in terms of specific specifications, the frequency may be slightly increased but the name will be changed to A16, and the A16 will be launched. The Pro chip is used in the iPhone 14 Pro models. If the iPhone 14 still uses a chip that has not changed much from the A15 as its core configuration, will it still have an advantage over other competing products launched in 2022? Does the iPhone 13 series using the A15 chip still have an advantage at this stage? For users, will there be a need for replacement due to insufficient performance? The author has recently used the iPhone 13 at hand and the Red Magic 7S Pro off-screen gaming phone for a simple comparison, from which we can obtain the answer to the question. Specifications From the specifications on paper, it can be seen that the A15 chip launched by Apple last year was manufactured using the 5nm process from TSMC, and the Snapdragon 8+ chip launched by Qualcomm in the middle of 2022 is also from Samsung Snapdragon 8. The foundry is transformed into a 5nm process foundry from TSMC. From this point of view, the manufacturing process used by the Apple A15 chip and the Snapdragon 8+ has not opened the gap, and considering that the progress of TSMC's 3nm process will not enter large-scale commercial use until 2023. Therefore, the latest generation chips of Apple, Qualcomm and even MediaTek are expected to be manufactured using the 5nm process from TSMC, and the improvement in the process technology of the new generation chips will be relatively limited. In Apple's own product system, if the internal micro-core architecture of its chips fails to be further improved and the IPC is improved, the gap between Apple's A15 chip and the upcoming new generation of chips from Apple will not be too large. . In the face of Qualcomm chips, we can see from the parameters that even the Apple A15 chip from 2021 faces the Snapdragon 8+ chip from 2022, although the number of cores is small, it is equipped with extremely high The terrifying 12MB L2 cache and up to 32MB SLC (system shared cache) are overwhelming advantages compared to the 2MB L2 and 6MB SL3 of the Snapdragon 8+. The cache of the A15 chip can satisfy the branch prediction and branch hit of its core through a larger capacity, and by improving the hit rate, it can give positive feedback to the performance of the core, which is a bonus to the performance. And thanks to Apple's good strength in chip design, under the superposition of various factors such as architecture and cache, the CPU performance of Apple's A15 chip is better than that of Snapdragon 8+ in actual use, and personal It is predicted that compared with the Snapdragon 8 Gen 2, which mainly optimizes the design direction for power consumption performance, it will also gain performance advantages in single-core. In the actual comparison, the author chose the iPhone 13 (A15 chip 4GPU version) and the Red Magic 7S off-screen gaming phone (Snapdragon 8+) for comparison. In the actual comparison, the author will manually close the Red Magic 7S off-screen game The active cooling fan of the mobile phone is compared with the passive cooling method. In this case, you can understand the Red Devils, a gaming phone, as a Snapdragon 8+ chip phone with very good passive heat dissipation and relatively aggressive tuning. First of all, in the GeekBench 5 test, the actual score of the iPhone 13 using the A15 chip is 1712 points for single-core and 44,554 points for multi-core. The actual score of the Red Magic 7S off-screen gaming phone using the Snapdragon 8+ chip is 1295 points for single-core and 4205 points for multi-core. It can be seen from the running points that Apple's A15 chip has a very strong advantage over the Snapdragon 8+ chip in terms of single-core performance at this stage, and this situation is even the Snapdragon 8 Gen 2 that Qualcomm will launch. It may not be possible to achieve overtake, and the gap is very obvious. In terms of multi-core performance, the Snapdragon 8 Gen 2 still has the hope of surpassing the A15 or tying it. In the Wild Life test of 3D Mark, because the author uses the A15 chip with 4 GPU version, the actual score is 2338 points. According to the 3D Mark list, the iPhone 13 Pro using the 5 GPU core A15 chip has a score of around 3100, while the Snapdragon 8+ chip has a score of 2731. In between the 4 GPU and 5 GPU of the A15 chip. △iPhone 13's 3D Mark Wild Life score △Red Devil 7S Pro's 3D Mark Wild Life score In a further actual game test, the author chose the recently updated Sumeru City map of "Genshin Impact", and the author used the main city of Sumeru City. The scene was run for 15 minutes with full special effects. The test conditions are that both mobile phones are kept at the same brightness, connected to wifi, and run at the same room temperature. In the 15-minute running map of "Yuan Shen" Xumi City, the author selected the 4 GPU version A15 chip and the Snapdragon 8+ chip mobile phone to run the map, and the detection data of the frame number and performance power consumption are owned by Tencent WeTest. PerfDog (PerfDog) provides technical support derived. △ Snapdragon 8+ frame number data △ A15 4GPU version frame number data After 15 minutes of running, both chips can run a full frame level close to 60 frames, and the overall fluctuation is not large. It can be said that for the current stage For the needs of "Yuan Shen", it can be better satisfied. The author uses the 4 GPU version of the A15 chip. If you switch to the 5 GPU version chip, the performance stability may be better. On the running map of Genshin Impact, the average power consumption of the A15 4GPU version calculated by PerfDog is about 5.2W, while the power consumption of the Snapdragon 8+ chip running through the balanced mode in the Red Magic 7S Pro gaming phone under the screen is The average power consumption is nearly 6W, and if it is further turned on to a more aggressive awakening mode, the power consumption can be pulled to nearly 7.5W. △A15 4GPU version monitoring power consumption △Snapdragon 8+ monitoring power consumption (Red Devils 7S Pro balanced mode) △Snapdragon 8+ monitoring power consumption (Red Devils 7S Pro awakening mode) Another Mihayou game "Honkai 3" In the second chapter of the post-collapse book, the author conducted a scene test of the Shuidui City, and the test scenes were all on the 11th-17th floors of the Shuidui City. △ Snapdragon 8+ Collapse 3 frame number data △A15 Collapse 3 Frame number data Through the technical support of PerfDog, it can be seen that both A15 and Snapdragon 8+ ran an average frame number of close to 60 frames. But overall, even the 4 GPU version of the A15 chip has better frame rate stability than the Snapdragon 8+, significantly less volatility, and lower average power consumption. The average power consumption of the 4 GPU version of the A15 is around 5.2W, while the average power consumption of the Snapdragon 8+ is close to 6W. △A15 collapsed three monitoring power consumption △ Snapdragon 8+ collapsed three monitoring power consumption (Red Magic 7S Pro balanced mode) Conclusion From theoretical data to actual running points and game tests, we can find that at this stage, even The 4GPU version of the A15 chip still has a very strong duel ability when facing the new Snapdragon 8+ chip launched in 2022. Therefore, even if the iPhone 14 uses the same 4 GPU core version of the A15 chip as the iPhone 13, it can easily parry when facing other competing products at this stage. According to the trend of Apple in recent years, some core configurations of the previous generation Pro series are generally distributed to the new generation standard version. The iPhone 14 standard version should also be the A15 chip or the frequency-boosting version with 5 GPU cores. The advantage in image processing capability is further improved, and it has a performance advantage over competing products. Therefore, for the iPhone 14, even using the A15 chip cannot change the fact that its performance is still strong at this stage. For users holding the iPhone 13 and iPhone 13 Pro series, it can be seen from the current comparison that compared with the Snapdragon 8+ chip launched by Qualcomm in the middle of 2022, the A15 chip can perform close to the performance. With better power consumption performance, it is overwhelming. And this performance may not be inferior to the Snapdragon 8 Gen 2, which may be launched by Qualcomm at the end of 2022, and Q1/Q2 will become the flagship chip of the Android camp in 2023. At this stage, when the iPhone 14 series has not been released, I personally think that users of the iPhone 13 series do not need to consider the need for replacement because of performance issues.
