The name Snapdragon 870 is certainly not unfamiliar to those friends who have recently purchased a machine with a budget of about two thousand yuan. The Snapdragon 870 launched in early 2021 has won the favor of many mobile phone manufacturers with its excellent energy consumption ratio and lower price than the flagship chip. Its strong market performance even extended to 2022, Xiaomi 12X and other new machines continue to use the Snapdragon 870 processor at the same time, but also the price down to about 1999 yuan, there is a great potential to continue the name of the king of mid-range machines to 2022 momentum.
However, the market will not always be so calm, earlier this month MediaTek launched the Tianji 8100 processor, as a new generation of sub-flagship chips, which is aimed at the current mid-range machine market controlled by the 870. According to the information previously released by the official, Tianji 8100 has a very good performance in terms of performance and power consumption. Of course, the official publicity we can not accept all the orders, Tianji 8100 what kind of performance does it have? Today we will pull out the Snapdragon 870 and snapdragon 888 brothers and Tianji 8100 together to compare.
01What is the difference between the three chips?
To understand the difference in performance between the three chips, we first need to know the differences in the underlying architecture of the three chips. In the CPU part, the three chips are all Arm public architecture, using 8-core design, but the specific models and parameters are different. Both the Snapdragon 870 and the Snapdragon 888 use a large, medium, and small three-cluster architecture, the Snapdragon 870 is a Cortex A77 (3.19GHz) + three Cortex A77 (2.42GHz) + four Cortex A55 (1.8GHz).
On the basis of the Snapdragon 870, the Snapdragon 888 replaced the super core and the large core with the updated Cortex X1 and CortexA78 architectures, and the super core and large core frequencies were 2.84GHz and 2.4GHz, respectively, and the architecture and frequency of the small core did not change.
The Tianji 8100 abandons the three-cluster design and consists of four CortexA78s (2.85GHz) and four Cortex A55s (1.8GHz), with larger cores operating at higher frequencies.
GPU part, Snapdragon 870 uses Qualcomm's own Adreno650, Snapdragon 888 upgraded to Adreno660, which has been improved in terms of performance and power consumption, and Tianji 8100 uses Arm's public version of Mali-G610 GPU, 6 core design.
Finally, many people are concerned about the process problem, Snapdragon 870 uses TSMC 7nm process, Snapdragon 888 is Samsung 5nm process, and Tianji 8100 uses TSMC 5nm process, which is relatively better.
Overall, with a more advanced process technology, Tianji 8100 abandons the mainstream three-cluster architecture and uses 4 large cores + 4 small cores to obtain better CPU performance, but in the GPU part, the public Mali-G610 is still slightly weaker than Qualcomm's Adreno GPU.
02 From running points to heating, the measured performance gap is geometric
In order to actually test the performance of the three chips, we chose the Xiaomi Mi 11, which launched the Snapdragon 888, the Redmi K40, which represents the cost performance of the Snapdragon 870, and the Zhenmei GT Neo3 equipped with the Tianji 8100. Before actual measurement, we first need to unify the test environment. For redmiK40 and Xiaomi Mi 11, we select the performance mode in the battery settings and the performance mode in the GameTurbo, while on the True My GTNeo3, we turn on gt mode. At the same time, set the screen brightness to 50%, turn off Bluetooth, sound, connect the same Wi-Fi, and test at room temperature of 25 degrees Celsius.
Running sub-software
The first is the running score part, although the running score does not summarize all the use scenarios, but as the most intuitive and quantitative test method, the results still have high reference value. In this session, we tested with Antutu and GeekBench, and the results are as follows:
Among the Antu Rabbits, the True Self GTNeo3 with Tianji 8100 score is 812738 points; the Xiaomi Mi 11 score equipped with Snapdragon 888 is 755747 points; and the RedmiK40 with Snapdragon 870 score is 689555 points.

In GeekBench, the True Self GTNeo3 equipped with the Tianji 8100 has a single-core score of 963 points and a multi-core score of 3972 points; the Xiaomi Mi 11 single-core score equipped with the Snapdragon 888 has a single-core score of 1118 points and a multi-core score of 3242 points; and the RedmiK40 equipped with the Snapdragon 870 has a single-core score of 961 points and a multi-core score of 3250 points.
GeekBench score (Xiaomi Mi 11, Redmi K40, True Me GT Neo3 from left to right)
Overall, in the Antutu test, the True Self GTNeo3 equipped with Tianji 8100 won the first place in the test score. In the GeekBench test, the Snapdragon 888 was more excellent in the single-core score, and the Tianji 8100 achieved a large lead in the multi-core score.
Game frame rate
With the continuous improvement of processor performance, today's mobile games are also evolving, the picture is more exquisite, the frame rate has increased from the initial 30 frames to today's 120 frames, followed by higher and higher performance requirements. In such a situation, whether the processor can provide enough performance to allow users to get a good gaming experience has become a concern. In order to simulate the extreme scene, we directly chose the real running score software "Original God" and tested it at 60 frames + extremely high quality, and the frame rate is as follows:
It can be seen that the Xiaomi Mi 11 using Snapdragon 888 is very conservative in performance, locking the game frame rate at 45 frames after experiencing a one-minute fluctuation, and reducing the frame rate to 40 frames after running the game for 4 minutes, after which it has stabilized at 40 frames until the end of the test.
Xiaomi Mi 11 "Original God" frame rate performance
RedmiK40 equipped with Snapdragon 870 appears to be more "open" during the game, but in the later stages, there is a large degree of frame rate fluctuations, although there is no obvious sense of stuttering during the game, but it can still feel that it is not smooth enough.
Redmi K40 "Original God" frame rate performance
Equipped with Tianji 8100, the True Self GT Neo3 is more relaxed in the game, even in the extremely high quality +60 frame setting can still ensure the basic full frame operation, only a few times during the game has appeared slightly stuttered.

Fever
If the heating condition is not ideal, it will have a big impact on the life of the phone itself and the user's experience. In order to detect the heat of the three mobile phones, after using the same setting for half an hour of "Original God" test, I used the temperature gun to test the fuselage temperature of the three mobile phones, and the results were as follows:
Xiaomi Mi 11 tests the body temperature after
Redmi K40 tests the body temperature after testing
True me GT Neo3 tested the fuselage temperature
It can be seen that due to the more conservative performance adjustment, the average temperature of the fuselage of Xiaomi Mi 11 is 39.0 degrees Celsius, and the maximum temperature of the fuselage is 43.1 degrees Celsius; the average temperature of the fuselage of Redmi K40 is 39.9 degrees Celsius and the maximum temperature of the fuselage is 45.9 degrees Celsius; the average temperature of the fuselage of the True Self GT Neo3 is 39.3 degrees Celsius, and the maximum temperature of the fuselage is 43.5 degrees Celsius, and the temperature performance is relatively close to that of Xiaomi 11.
03 Summary
Overall, thanks to the updated architecture and better process technology, Tianji 8100 has obvious advantages over Snapdragon 870 in terms of performance and heat, and Although Snapdragon 888 is more powerful in performance, it has higher requirements for the manufacturer's adjustment ability.
