Since the vivo Xplay3S released at the end of last year, mobile phones have officially entered the era of 2K (2560 * 1440). Although there are only a few mobile phones with such high resolution, this is indeed the development trend of the industry. The higher resolution puts forward new requirements for the memory bandwidth and GPU performance of the mobile phone. Compared with 1080P, what is the difference between the performance of the 2K screen on the mobile phone with the same configuration? Let's take a look at today's test:
To be fair, the two phones in this comparative test try to keep the same except for the screen resolution. We use OPPO Find 7 Standard (2K screen+MSM8974AC+3G Ram+32G Rom, ColorOS 1.2) and One plus mobile phone (1080P screen+MSM8974AC+3G Ram+16G Rom, ColorOS 2.0). It can be seen that the two use the same SoC, namely the MSM8974AC of Qualcomm Snapdragon 801 series. This chip uses a quad core Krait 400 2.5GHz, with 578MHz Adreno 330, plus dual channel LPDDR-3 933MHz (memory bandwidth up to 14.9Gb/s), which is the most commonly used chip in high-end mobile phones.
In addition, the "physique" (PVS value) of the standard version of Find 7 we tested here is 5, while the "physique" of one plus is 8, which may have some impact on the frequency reduction of the processor in the game. This individual difference is normal for both the evaluation machine and the retail version we buy on the market.

GFXBench 3.0
This is a common GPU performance test. In the past, we used Offscreen, that is, off screen testing. The equipment was tested in a 1080P environment, which shows the performance gap of pure GPU. This time, because we mainly consider the impact of resolution on performance, we use Onscreen to test. Here are the test results:
Because of the high resolution of Find 7 standard version, the number of scene frames in such high intensity operation is really ugly. The Manhattan scene even has only 6.6 frames.
For one and the other, Offscreen and Onscreen are both 1080P, so you are familiar with the frame numbers of these two scenes and they play normally.
Next is the game measurement. According to the convention, we first present the "Three Day King of Racing". These three racing games are the best in Android games in terms of gameplay and game special effects.
Wild Racing 7 (1.1.1)
Wild drag racing is a classic racing game of Gameloft. Although the game has been upgraded to the eighth generation, the maximum frame number of Wild drag racing 8 is limited to 30, so we still use the Shanghai track with the highest performance requirements in Wild drag racing 7.
The first is the standard version of Find 7. This is not the game limit frame number, but the average frame number is 31 after playing a round, which means that many times the frame number of the game is less than 30, so it is not very smooth to play, but users with low requirements will not feel that there is any big problem.
Needless to say, Yijia's performance is close to full frame in the whole process. It's really impressive to have such an effect under full HD resolution ▼
Real Racing 3 (2.3.0)
In this game, the performance of the standard version of Find 7 is fairly good. The average frame number after a round is 45. At the beginning, when there are many cars, the frame number is more than 30 ▼
In this game, Yijia doesn't have a gap with Find 7. The average frame number is only 2 frames higher in a circle, so when Find 7 runs this game, it may be at 1080P resolution ▼
Jipin Feiche 17 (1.5.01)
The best speed car 17 is also our old friend, and the version number has never been updated, but it has high support for Snapdragon 801. The average frame number of Find 7 standard version is 33, which is not very high ▼
The average frame number of this game is more than 10 frames higher than that of Find 7, but it has not reached the effect we imagined ▼
Modern War 4 (1.1.6)
Since the special effects of Snapdragon 800/801 are relatively low when running Modern War 4, and the pressure on the GPU is not high enough, we use the "artifact" GLTools (requiring root) to forcibly simulate the GPU into SGX544 before running the game.
The screenshot of GLTools settings is as follows:
The standard version of Find 7 performs well in this game. After the fierce battle at the beginning of the game, it can achieve an average score of 39 frames, basically ensuring the smoothness of the game ▼
It seems that GLTools may limit the performance of GPU after simulating GPU, and the number of frames in this game is not high, just 3 frames higher than Find 7 ▼
Comparison of the above test frames table:
Frame number curve comparison:
From this game test, under the same condition of using MSM8974AC, the performance of mobile phones with 2K screens in large-scale games is indeed significantly different from that of mobile phones with 1080P screens. Among the several games we tested, the standard version of Find 7 can only guarantee relatively good fluency in real racing 3, and there is a big gap between wild racing 7 and top class racing 17. Of course, for such a large game, we can be forgiven for the poor performance of the 2K screen phone, and the MSM8974AC has been able to better meet the requirements of the 2K screen in daily use. Before the deadline, the Samsung Galaxy S5 LTE-A with Snapdragon 805+2K screen has been officially launched in South Korea. We will also present the performance test of this new flagship phone for you at the first time.
