Screen：LTPO adaptive variable high frame rate, high resolution, high refresh screen can also save power
Screen part，The screen of OnePlus9 Pro still supports 2K 120Hz 10bit, these luxurious parameters，Upgraded to the latest E4 luminescent material，The brightness has also increased to 1400nit。Official ultra-high precision calibration，Ensure that every pixel of each OnePlus9 Pro can be the most accurate、Natural colors。Enhanced engine through image quality，It can improve the image quality of low-resolution videos，And improve the smoothness of the picture through the MEMC frame filling function。
but，We are mainly focusing on two new features this time：Adaptive refresh rate and game overclocking response。
——Adaptive refresh rate
OnePlus9 Pro uses new LTPO OLED，This realizes the new function of adaptive refresh rate。On traditional LTPS OLED，Due to the high leakage current of LTPS，Therefore, the screen needs to be refreshed continuously、Recharge the charge to maintain its normal working condition，Adaptive refresh rate cannot be achieved。
And under the new LTPO technology， The addition of IGZO materials greatly reduces leakage current，This greatly reduces the lower limit of the refresh rate。This screen of OnePlus9 Pro，Only refresh once a second to replenish charge， 1This is how adaptive refresh rate synchronization of Hz-120Hz is achieved。
Because of the self-luminous characteristics of OLED screen，Its power consumption is mainly concentrated in each refresh of the screen panel pixel points。The lower the refresh rate，The lower the power consumption。therefore，In daily use scenarios，Pause the sliding screen whenever you read content，The refresh rate will automatically decrease to save power，Increase again when sliding，Realize the infinite change between 1Hz-120Hz。
therefore，Its power saving is also reflected in daily use scenarios，There is almost no improvement in heavy use scenarios。According to everyone's use habits，Its power saving effect is also different，Need to feel it in fact。
——Game overclocking response
Game overclocking response is an additional benefit based on LTPO hardware，This technology can increase the synchronization frequency between screen and processor by 3-6 times，Game delay is reduced by 25ms to 30ms，Greatly reduce screen response time。
Once upon a time，Speaking of control and hand，We often mention OnePlus，And this time，OnePlus9 Pro will bring a more handy experience。
OnePlus9 Pro Performance：Multiple scheduling modes meet different needs and ultimate modes are comparable to game flagships
all along，OnePlus' performance scheduling is unexpectedly radical，Full performance release when running score，Even compete with the gaming flagship。But this generation，OnePlus9 Pro's scheduling has become much more conservative，Pay more attention to performance and heating in daily use、Equalization between power consumption。
- Theoretical performance test
1、Master Lu：In the mobile phone test of Master Lu，OnePlus9 Pro scores 875,146 points，Obtained the 8th ranking of performance in the overall list。
2、GeekBench：GeekBench generally uses GeekBench 5 as the benchmark reference，OnePlus9 Pro Single Core Score 1099，Multi-core score 3449，A normal level of Snapdragon 888。
3、Androbench：OnePlus9 Pro continuous reading speed 1540 MB/s，Continuous write speed 404.46 MB/s，Normal performance of UFS 3.1。Snapdragon platform encryption algorithm will cause UFS 3.1 to be tested at a low speed，Therefore, the comparison speed between different platforms is not of reference significance。
4、GFXbench：Compare with the Snapdragon 888 flagship scores tested in the past，In the first few tests of GFXbench，OnePlus 9 Pro scores are very good，But in the second half，The running score of OnePlus9 Pro begins to gradually lag behind the reference template，This should be mainly because the OnePlus9 Pro's scheduling is relatively conservative。
——Game performance test
1、King of Glory：The highest quality gameplay "Honor of Kings"，OnePlus9 Pro never reaches full frame of 90FPS，But the frame rate is stable，The average frame rate is 79.9FPS。
2、Peace Elite：OnePlus9 Pro is not yet adapted to Peace Elite's high frame rate mode，Therefore, we chose HDR HD+60 frame mode with high load for testing，Except for a slight fluctuation, the frame rate of the entire process is basically above 59FPS.，Average frame rate of 59.4 FPS。
3、Ace Warrior：Because "Ace Warrior" forces a lock frame 60 when the character is waiting for resurrection，To avoid interference，So the data is filtered，Show only the frame rate of the battle process。"Ace Warrior" has high compatibility with high frame rate mode，The average frame rate of the game can reach 118FPS，Excellent optimization。
4、Genshin："Genshin Impact" We set the highest image quality + 60 frame mode，Perform performance testing according to the path shown in the figure。
OnePlus9 Pro performs worse in Genshin Impact，Stuttering occurs more frequently，You can see that the fluctuations in the second half are particularly frequent。but，In the author's opinion，This is not to say that the performance of OnePlus 9 Pro is not released enough，It's because it's enough to optimize the game。
Long before，We will come to a conclusion - "Genshin Impact" is currently a CPU game on Android.，It basically won't take up too much GPU performance。
One minute after the "Genshin Impact" game started，Extra-large and large cores are directly passively slacking off，Only small cores work full load，This is natural for a stuttering.。
Whether it is theoretical performance testing or actual game testing，The heaviest load of "Genshin Impact" and GFXbench，The core temperature of OnePlus9 Pro is not higher than 51℃。In sharp contrast to this，Those models with excellent running scores，The core temperature often reaches a height of 76°C in the test，OnePlus 9 Pro's strict temperature control and conservatism can be seen from this。Don't know when it's officially released，The system's scheduling in game scenarios can be improved。
