In this regard, to further test the performance of OPPO K12, we turned off the memory expansion function of the phone, turned on the high-performance mode, and conducted a set of theoretical performance and game performance tests.
Performance Testing
In the AnTuTu comprehensive test, OPPO K12 scored a total of 894,000. Compared with the previous generation K11, the overall performance was nearly 24% ahead.
CPU single test, Geekbench6 single-core score 1161 points, multi-core score 3012 points, compared to the previous generation is not a big improvement, but in terms of GPU, the improvement is very big. In the GFXBench test, this generation of Snapdragon 7 Gen3 is better than the Snapdragon 7 Gen3 equipped with the previous generation K11. Dragon 782G has a lead of more than 45%.
In the flash memory test, the read and write speeds of 1830.1MB/s and 1718.51MB/s are in line with the level of UFS3.1.
Game testing
In the game test session, we selected two mainstream mobile game masterpieces, namely “Honor of Kings” and “Peace Elite”, and tested them in an indoor office environment of 26 degrees Celsius with frame rate priority. During the test period, we turned on E-sports mode recording the frame rate of the game and the heating performance of the phone.
1. King of Glory
According to the actual measurement of the Honor of Kings mobile game, the frame rate of 5V5 team battles can run at 120FPS. The average frame rate during the entire game is stable at 120.48FPS, without the slightest sense of lag, and the frame rate is surprisingly stable.
In terms of temperature, after a team battle, the maximum temperature on the front of the fuselage was 36.5 degrees Celsius, and the maximum temperature on the back was 35.6 degrees Celsius. This temperature was almost insignificant during the game.
2. Peace Elite
For the medium-to-high-load Peace Elite mobile game, under extreme frame rate + HDR high-definition image quality, after a fierce battle, the average frame rate stabilized at 59.89FPS. There was no significant frame rate fluctuation during the test, and the game screen was special.
In terms of temperature, it is naturally higher than the King. The maximum temperature on the front of the fuselage is 39.7 degrees Celsius, and the maximum temperature on the back is 39.4 degrees Celsius. It is very worthy of praise that it does not reach 40 degrees Celsius.
Cameras
The OPPO K12 main camera uses a 50-megapixel Sony IMX882 sensor with a 1/1.953-inch photosensitive unit and supports OIS optical image stabilization.
The ultra-wide-angle lens is an 8-megapixel Sony IMX355.
Main Photographer
In daytime scenes, the proofs taken by the main camera show a style that is loyal to reality without excessive saturation.
Even under backlight conditions, thanks to advanced light and shadow processing technology, the camera can still capture and retain the details and layering of the picture, presenting clear and detailed pictures.
Night view
In the night scene, using the long exposure sample, you can see the outline of the lamps around the light, the color is pure, and there is no particularly obvious color cast.
Moreover, thanks to the blessing of OIS optical image stabilization, the shooting rate of night scenes is greatly increased. There is no need to deliberately stabilize the phone, and the objectivity of the straight-out photos is very good.
Super wide angle
The ultra-wide-angle lens is more suitable for recording some buildings and scenes with a larger viewing angle. The 8-megapixel lens can also show magnificent tension as long as you don’t zoom in and take a closer look.
