Recently, with the launch of Snapdragon 865, 765, MT6889, and Samsung 980, the topic of mobile phone SOC performance scores has become hot again. In fact, mobile phone running scores are an old problem. Mobile phone manufacturers always want to prove that their products are faster, so they use their brains in running software to make their running scores higher.
Some manufacturers, in the gaming GPU test, reduce the resolution, strive for higher scores and better performance and power consumption ratio.
Some manufacturers cheat on the memory items in the CPU test, and specially design a small piece of cache to deceive the running software to obtain a higher memory score, thereby improving the processor’s score.
Meanwhile, manufacturers simply invest in running test software, making CPU, GPU, memory, and UI running tests a hodgepodge. Comparing total scores makes little sense.
So, how should we look at the running score of the mobile phone? What kind of running score can hang on with the performance experience?
First, how to look at the CPU performance of the phone?
Since ARM A15, mobile phones have been popular for large and small cores, big cores run extreme performance, and small cores handle daily small applications, so that mobile phones can save more power and improve their battery life.
For users, the typical application scenario is 90% of the time. It only requires the performance of a small core and does not need to be fully loaded. Only 10% of the time, 100% of the small core is still not enough, and the large core needs to work hard to improve the response speed.
So, to the user, the mobile phone is not fast, and it is invisible everyday. The memory is faster, the flash memory interface is faster, and the screen refreshes at 90hz and 120hz, which are more powerful than the processor.
The real test of the mobile phone processor is the heavy-duty tasks, such as loading large programs on the mobile phone and opening large applications. At this time, the extreme performance of the large core of the mobile phone is most needed.
Burst tasks call 100% big cores. Big cores are faster and mobile phones are faster.
So, when we reached Qualcomm 855, we came up with an independent high-frequency core.
This performance is actually the single core extreme performance of mobile phones.
Testing the single-core extreme performance of mobile phones, there are APPs such as AnTuTu, Geekbench, Master Lu, etc. Unfortunately, this kind of software is often targeted for cheating, and the results are not accurate.
The more reliable is the cross-platform SPCE CPU software. This set of things is a set of source programs. The versions are SPCE CPU Speed 2000, 2006, 2017, and fixed point and floating point.
The test principle of this program is to take out the actual computing task source program running on the workstation server and use a workstation of the year as the standard. You can get as many times as faster than the workstation of the year. Points, each task is weighted again, and a total score is obtained.
Because this set of things is not for mobile phones, and the source program is taken out to run, it is difficult to cheat. To optimize, you can only do it at the compiler level. This can only be done by Intel, so it is very reliable.
So, whether it is Intel, AMD, IBM or Godson, Feiteng, Kunpeng, run this program.
On mobile phones, the SOC on the tablet can also run. This score is real performance.
So, how powerful is the phone processor?
Apple uses a very complex and powerful architecture (complexity has reached the level of desktop processors and high power consumption), the most powerful performance, A13 integer can run 52 points, floating point can run 65 points. The A12 integer can run 45 points and the floating point can run 54 points. Far more than other mobile phone processors. Already close to the latest desktop processors.
Intel’s 9900K, with an integer of 54 points and a floating point of 75 points.
The Snapdragon series is weaker, the latest 865, with an integer of 33 points and a floating point of 48 points. 855plus is an integer of 26 points and a floating point of 37 points. 845 integer 17 points, floating point 23 points, 835 integer 13 points, floating point 16 points.
The Snapdragon 7 series and 6 series are even weaker.
Don’t underestimate this score. The latest domestic processor Godson has been specially optimized to only score 20 points.
Huawei’s Kirin series, Kirin 990 and Snapdragon 855 use the same core, but the frequency is slightly higher, so the integer is 28 points and the floating point is 39 points.
Kirin 980 is weaker, with an integer of 26 points and a floating point of 34 points.
The Kirin 970 has an integer of 13 points and a floating point of 16 points, which is similar to the Snapdragon 835.
Second, the performance of mobile GPU
Mobile GPUs are more demanding than CPUs, because the high performance of the CPU is finished after a short run, most of the time with small cores, high peaks, and fast user experience.
The GPU has to run all the time, because the game always has high requirements on the GPU.
Some manufacturers plugged the GPU with a lot of cores in order to run points. They pulled up to a very high frequency and ran for dozens of seconds. The test score was very high, but running the game would reduce a lot of performance after a while.
So GPU running points can’t be viewed as running points, but long-term continuous performance. This is a real experience.
Long-term performance, not only the GPU problem, but also the heat dissipation problem of the whole mobile phone. Also using the A12 processor and a larger Mini5 tablet, the continuous performance of the XS mobile phone is much higher. Although the two runs, the GPU performance of tens of seconds is basically the same.
So which phone is more powerful when you really run games?
We can test it out with long-term stable test software frames.
Of course, the strongest is Apple. The iPhone11 Pro MAX runs GFXbench’s Manhattan off-screen, which can continue to reach 98 frames (the peak time is 123 frames). Is currently the strongest gaming phone.
With the same processor, the iPhone 11 with a much smaller phone size (meaning much worse heat dissipation) can only run 80 frames (the peak is also 123 frames). This 80 frames is truly usable performance.
The ASUS ROG PhoneII with enhanced heat dissipation, although the peak is only 81 frames, but the heat dissipation is well done, and it can continue to run at 80 frames. The theoretical performance is only two thirds of the iPhone11, but it really runs, relying on excellent heat dissipation, performance It’s the same, this is the strongest Android gaming phone.
The OPPO Reno 10X is also a Snapdragon 855, but the heat dissipation is not so exaggerated, so it can only run for 70 frames.
The iPhone XS’s A12 processor is also very strong. It can run at a peak of 104, but it can only run 61 frames, which is not as good as 855.
Huawei’s Mate30 Pro is similar to Apple’s, with a peak performance of 75 frames and a sustained performance of 57 frames.
Samsung note9 is relatively large, with a chip of 845 and a peak of 60 frames, which is far worse than Huawei Mate30 Pro, but it can continue to run 52 frames.
The S9 +, which also uses the 845, can only run for 35 frames.
Huawei Mate20 Pro lasts 32 frames, although it peaks at 54 frames.
So, the game mobile phone depends not only on the extreme performance, but also on the continuous performance.
Three, the strongest phone
From the current situation, the strongest mobile phone has no suspense, that is, iPhone11 Pro MAX, with the strongest CPU and the strongest GPU.
Although its sustained GPU performance is 20% lower than the peak value, it is also the strongest after the drop.
If you give ASUS ROG PhoneII heat to iPhone11 Pro MAX, let its SOC
