The current C5 Pro, C7 Pro and C9 Pro of Samsung's "China Special Machine" C series are the second generation products. Compared with the original generation products, they have more changes for the Chinese market, and also continue to become the international version. Previously, we Love to play computer games This article explains the changes in the appearance design of the C7 Pro. What is the upgrade of the whole model?
Chinese style appearance
We like to play computer games in " Samsung Volkswagen Face? Galaxy C7 Pro The appearance changes of Samsung's C-series models were introduced in more detail. It can be seen that the entire design style of the C7 Pro caters to the current domestic fashion trend. It can be said that even if Samsung's logo is removed and another brand is replaced, the C-series machines will not be incompatible. As a mass market model, the C series is very conservative in appearance, without the unique feeling of Samsung on the flagship.
Stable display
The C7 Pro is equipped with a 5.7 inch 1080P Super AMOLED screen, which continues the traditional look and feel. The default adaptive display mode is more gorgeous, which will be more pleasing to people who are "heavy taste". If you don't like it, it is recommended to change to the basic mode. Use the most accurate basic mode for testing. The maximum brightness under manual conditions is about 330 nits, and the color gamut can cover 99.3% of sRGB.
The color temperature in basic mode is 6400K, very close to the standard 6500K. The test result of 104 color calibration shows that the average DeltaE is 2.9, and the maximum DeltaE is 4.9, which is normal for Samsung. At the same time, there is a certain gap with the flagship model, reflecting the positioning of the C series.
Predicted performance
C7 Pro has made a very small upgrade on the processor compared with C7 - it has changed from Snapdragon 625 to Snapdragon 626, the same 4G+64G storage combination, so in fact only the main frequency of the processor has soared from 2GHz to 2.2GHz, which is the same in other aspects. The same architecture only increases the main frequency, so the performance should be improved slightly, but it is impractical to compete with the higher end SoC.
The actual test also shows that the scores of both single core and multi-core machines have increased to a certain extent compared to the Snapdragon 625 machine, especially the multi-core performance has improved significantly, especially in the test of GeekBench 4, which has increased by more than 1000 points compared to the 3000 points of the Snapdragon 625. It can't help but wonder whether the Snapdragon 626 is specially optimized for the scores.
However, there seems to be no improvement in GPU compared with CPU - except for 0.1 frame improvement in GFXBench Manhattan test, the rest of the test items are completely consistent with Snapdragon 625. Since Qualcomm did not indicate the frequency of the GPU when it released it, the test results show that Snapdragon 626 may not upgrade the GPU compared with 625.
The C7 Pro system is based on Android 6.0.1, and the UI is naturally customized by Samsung. The C series system is almost the same except for the cell. The smoothness of the whole system is good. With sufficient memory, there is little need to manage the background in daily use. Of course, it will be difficult to run large games due to performance limitations. At the same time, Samsung has also made some localization for the domestic environment, which is quite sincere among international manufacturers. It is not clear whether it is due to the National Bank of China that Samsung Milk Music, which has stopped service, can still be used on the C7 Pro normally.
Photos with acceptable performance
The camera interface of the C7 Pro maintains Samsung's consistent style, provides multiple mode options, and also adds special watermarks and filters that girls prefer. The shutter and focusing speed are both fast. With the shortcut of double clicking the Home key, the user experience is good. The CMOS used by the C7 Pro is Samsung's own S5K3P8, which is superior to the C9 Pro in terms of parameters. How about the actual imaging?
Daytime performance
As a natural brother, the samples of C7 Pro and C9 Pro are quite similar. C7 Pro is slightly better than C9 Pro, mainly because it is superior in white balance and details. After zooming in the proof sheet, you can see that C7 Pro handles the font edges better, but the gap is not big.
In the complex environment of the supermarket, the advantages of C7 Pro will be obvious. The overall white balance will be better, and C9 Pro will be relatively dim. At the same time, the text part will appear relatively "fleshy", with a slight lack of sharpness, and the overall appearance will be much weaker than C7 Pro.
However, when referring to the samples of some scenes, it seems that the lens of C7 Pro is not as good as that of C9 Pro, and the glare is a bit serious; At the same time, the sample of C7 Pro tends to be red, which makes the color of notebook in this group of contrast samples quite prominent.
There is not much difference between the performance of macro and that of C9 Pro. C9 Pro just lost the white balance, and the samples are cold. Both show different reds in the head, chest, hands and feet, and there is no difference in the details.
Nocturnal performance
The performance of the C7 Pro can be said to be slightly better in the daytime, but the performance at night is not as good as that of the C9 Pro. From this group of samples, it can be clearly seen that C9 Pro is more excellent in details, white balance and noise control.
Among other samples, C9 Pro also presents better samples than C7 Pro. The details of light and dark parts, noise control and better glare control can only be said to have a win or lose in terms of white balance. However, although it is better than C7 Pro, it is not practical to require night scene performance like S7, and the actual proof can only be said.
More samples of C7 Pro are attached:
In general, the performance of the C7 Pro in the daytime is not bad, but it is hard to cope with the ordinary scenes in the low light environment. Considering the positioning of the C series, such strength is reasonable.
Remarkable endurance
The C7 Pro is equipped with a 3300mAh battery. Considering the power consumption of the SoC and the mature Super AMOLED, the actual endurance of the C7 Pro should have a good result. After our regular 3-hour endurance test, the C7 Pro still has 82% of power left. This endurance can be used generously.
Final
Compared with the big brother C9 Pro, the reduced size of the C7 Pro seems to be more "just right" for Samsung's advertising. It is obvious that Samsung is targeting OPPO vivo、 The models launched by Huawei are slightly different from the customer base of Xiaomi and Meizu. From the C5 Pro to be listed, it can be clearly seen that Samsung is going to fight against them with the C series, which has caused a storm in the Chinese market.
