In recent years, Samsung's flagship has adopted a dual version strategy (except for the Galaxy S6/Note5 generation), and there will be some differences in performance and photos between versions. In the case that many media have not even obtained the Galaxy S8, we Love to play computer games The dual version Galaxy S8/S8+has been tested.
The content of the virtual home key, face recognition and Exynos version can be stamped The most detailed and comprehensive experience evaluation of Samsung Galaxy S8/S8+ 、 Samsung Galaxy S8/S8+Evaluation Video of Exynos 8895 。 This time we are bringing a detailed evaluation of the S8/S8+of Snapdragon 835. According to the experience of previous years, the Exynos version will win more. What will happen this year?
PS： Because the Bank of China may not be launched until May, the firmware tested is still an early version, and the performance of the final version may be different.
parameter
Appearance and workmanship
The most striking thing on the front of the Galaxy S8/S8+is the rounded curved screen with ultra-high screen proportion. There is no logo on the front, The overall outline of the fuselage is very similar to that of the Galaxy S7 (the outline of the mainframe is more like Note7).
Double curved face scale design, the position of flash lamp and heart rate sensor is moved to the left, and the fingerprint identification module is placed on the right, which cannot be pressed, but the notice bar can be pulled down/folded by sliding (only the first level can be pulled down, and cannot be pulled down completely). The front is very impressive, but the back is He is suspected of "slacking off and squeezing toothpaste".
This year, the front of all versions is black, but only the black version has black borders. In terms of wheel integration, the black version will definitely be the best. The black coating under the glass has slight color difference under different light and angles. However, I have to complain that the glass on the back cover of the testing machine does not seem to have anti fingerprint coating, and it is a fingerprint at hand. I hope that mass production will be able to repair the coating.
Familiar body layout: the right power supply and the left volume button have been changed to the integrated design, and the Bixby button has been added. The bottom is the headphone, Type-C interface, microphone and speaker openings, and the top is the card slot (there are more Qualcomm 4G stickers than the Exynos version). All versions of the Bank of China are dual cards, which adopt the "AND or card holder" design. You can insert dual nano SIM cards or nano SIM cards+mirco SD cards at the same time (users who need to expand dual cards and memory cards can only stick the sim card to the memory card by themselves).
The glass is higher than the metal frame and there is no transition of plastic washer. The fitting is very tight and the workmanship joint is impeccable. The radians of the front and back surfaces are the same, and the 2.5D radians of the upper and lower glass edges are smaller than those of the previous generation. The metal frame has a bright surface coating, and its color is similar to that of the bright black iPhone (the blue version has a blue frame, while the silver version has a silver frame). The specific scratch resistance is unknown, and it must be better than that of the bright black version. No scratches are found in normal use, but its ability to stain fingerprints and dust is not fundamentally different from that of the iPhone.
Galaxy S8/S8+Appearance Comparison
The corner radians of the Galaxy S8/S8+are close, resulting in a larger screen that looks more like an enhanced version of Note7. The 3D control of the two machines is very good (the width of the S8+on the 6.2 inch screen is only 0.8mm larger than the S7 edge). It is difficult to find that the S8+is a large machine when it is placed alone. When testing, you often have to reflect to find out which one you have taken.
The real S8 with a 5.8 inch screen is very small. Its size is close to that of Huawei P10 with a 5.1 inch screen. It has excellent hand feel and one hand control. The width of the S8+is not a problem, but its length is close to that of the 6-inch screen model. If it is placed in a slightly tight jeans pocket, it may top the pocket.
In terms of false touch, there are not many false touches on the left and right sides during single hand operation, but there is still a high chance of false touch when pulling the notice bar or clicking the upper button. In terms of virtual keys, because the chin is very narrow, the final position of keys is very close to the common models of Samsung models, and unexpectedly there is not much customary cost.
screen
The Galaxy S8/S8+is equipped with 5.8 and 6.2 inch curved corner 18.5:9 screens respectively, with a resolution of 2960 × 1440 (the system's default mode is to render at 2220 * 1080 resolution, which requires changes in settings or device manager to render at full resolution). The PPIs of the two machines reach 570 and 529 respectively, support HDR, pass the UHD Alliance certification, and comply with the 4K HDR video playback standard.
All versions of the screen are consistent. The maximum manual brightness of the S8 screen is 365 nits, and the maximum brightness of the full white screen is about 600 nits under strong light. The color temperature of the basic mode is colder than before, reaching 7000K. The deltaE (the smaller the better) averages 2.7, and the maximum is only 5. The overall data is still excellent, but in the curved screen, S6 edge has the best color accuracy. For comparison, iPhone 7 is 1.6, Note5 is 1.8, S6 edge+is 2.6, and S7 edge is 2.9.
Limit brightness and redness: Under the condition of strong light irradiation in the automatic mode and the reduction of white display area, the extreme brightness of S8 can reach 909 nits, and that of S8+can reach about 875 nits. The extreme brightness score is slightly weaker than that of Note7, but it is not ruled out that this is the individual difference of the tester or the limit of the instrument. In addition, it is worth noting that the four BOC Galaxy S8/S8+we got have a certain degree of screen reddening tendency, and the screen will turn red if the upper and lower angles are slightly larger. This is not the case on the European version G950F/G955F before. I hope it is just an individual problem of the test machine.

The system of the Bank of China version is slightly different from the European version G950F/G955F, There are some more functions that are very grounded (of course, most of them are already available on S7): the device manager has automatic start control, detailed flow control, the brightness adjustment of the pull-down bar can choose whether to display directly when it is pulled down for the first time, the shortcut switch of the notification bar can adjust the density of buttons, the telephone has yellow pages, the SMS has type label classification The multi task interface has full screen stretching shortcut buttons.
Special proportion adaptation and difference between large and small machines
2K15 will have black edges by default
This year, the Galaxy S8/S8+uses an 18.5:9 scale screen. Applications that strictly follow Android design specifications can generally adapt automatically. However, Android platform applications, especially domestic applications, are mixed. Actual test, UC /For information applications such as JD, games such as 2K15/2K17/Crash 3/Rapids/Temple Escape, which are enabled by default, will not automatically stretch, but will have black edges.

However, in the system of BOC, there is a "full screen stretching" button on the multi task interface, which can forcibly stretch the application. This is a new function in the game assistant of BOC Samsung. After automatic full screen, the effect is quite natural. For example, UC, Jingdong, Rapids, Collapse 3, etc., all more than 20 third-party applications can be displayed in full screen.

The escape of the temple can not be stretched perfectly. The screen entered by the game is not flattened, but stretched horizontally and vertically, so the horizontal edge content is lost
Auto stretch effect: Most applications can lossless full screen display. In some games and information applications such as King Glory, a longer screen will have a larger view and can display more content. However, NBA 2K17 stretches the image directly, and the image map will be flattened, which makes it impossible to use the extra field of vision of 18.5:9; The temple escape even has the situation that the start image is stretched vertically and horizontally (the edge image is lost), and the virtual key bar is still reserved... GPU GFLOPS, a cool application, also has the problem that the content overlaps with the notice bar on S8+(the right side of the figure below).
The left two sheets are before and after S8 stretching, and the right two sheets are before and after S8+stretching
The left two are yellow pages of S8 and S8+, and the right two are browsers of S8 and S8+
Comparison of display contents between large and small computers: On the 5.8 inch screen S8, the notification bar and virtual key bar are wider. For ordinary applications that are not full screen displays, whether they are stretched or not will not greatly improve the experience.
and S8+with 6.2 inch screen Higher DPI (higher content display density) In the same application, the actual display of each element is similar to that of S8, The same application can display one or two more lines. S8+is not only larger before and after stretching, but also has more obvious advantages in displaying content after stretching the full screen. For deep users or game players, S8+will have a broader vision, and it will be a more suitable tool for "cheating".
performance
We like to test the European version of G950F/G955F before operating the machine, and use Samsung's own Exynos8895 (Asia Pacific version, Korean version and Taiwan version all use this processor) The national travel, Hong Kong, Japanese and American versions are Qualcomm Snapdragon 835.
Performance analysis: Kryo on Snapdragon 820 is Qualcomm's first fully self-designed 64 bit CPU. This unique architecture is based on floating point IPC performance (The number of instructions that can be processed per week can be generally understood that performance=IPC * frequency) Very strong, but the integer IPC performance is not as good as that of the A57 architecture before ARM (the previous generation of A72), and the energy efficiency ratio is also lower. but This year, Qualcomm abandoned the previous generation of completely independent architecture. The new Kryo 280 core is most likely to be a modified version of 4-core A73+4-core A53, Apart from the name, it has no inheritance relationship with the original Kryo architecture.
Snapdragon 835 The CPU performance is also very close to that of A73 on Kirin 960. The performance of integer operation IPC has significantly improved compared with 820/821, but the floating point performance has decreased compared with the previous generation (integer operation affects the daily application speed, and floating point operation more affects the graphics performance).
In terms of GPU, the Adreno530 architecture on Adreno 540 and Snapdragon 820 is not very different, A small optimization was made to avoid the previous bottleneck, and ALU and registers were optimized. By improving the depth rejection filter, the computing load of each pixel is reduced to improve performance and reduce energy consumption. Plus The 10nm process enables it to achieve higher frequency (from 624MHz to 710MHz). Qualcomm claims that its 3D rendering is 25% higher than that of the 820 Adreno 530. However, the GPU frequency on S8/S8+is only 670MHz, and the actual performance increase is expected to be only 15-20%.
Comparison object: We use the full frequency Snapdragon 835 prototype (the highest main frequency is 2.45G, the highest GPU is 710MHz), the S8+representative of the same generation Exynos 8895 (the highest frequency of the G955F tester can reach 2.5G), the one plus 3T representative of Snapdragon 821, the glory V9 representative of Kirin960, and the S7 edge representative of the previous generation Exynos 8890 for comparison. Detailed comparison can be used to show that we love computer Running points library see.
CPU operation performance test
On the balance of performance and endurance, Samsung has always been more inclined to tuning and endurance, and the Bank of China S7 edge is the Snapdragon 820 model with the lowest performance. Unfortunately, this tragedy is likely to be repeated on Snapdragon 835.
Because the maximum main frequency is only 2.36GHz, the CPU performance of the Bank of China S8/S8+is not as good as that of the Snapdragon 835 prototype. The Snapdragon 821/Exynos8890 won a year ago is not a big problem, but it still lost to its European S8+(8895), Kirin960 (Glory V9) and Snapdragon 835 prototype, which are among the three flagship SoCs of this generation, temporary The weakest CPU. On the other hand, the 8895 can still compete with the 835 prototype and the Kirin 960 in terms of Samsung's tuning, with gratifying results.
GPU graphics performance test
The performance of Snapdragon 835 is furious. Although it is not as good as the 835 prototype, the performance of the Galaxy S8/S8+only has 670MHz GPU, which has left the previous generation of Snapdragon 821 and Kirin960 and other competitors, and even more, the previous generation of Exynos8890 is rubbed on the ground.
This unprecedented graphics performance can be run at a lower frequency than the previous generation on the game, with lower GPU occupancy and better heat control. On NBA 2K15/2K17, which is still a showdown in 821, the GPU of the Galaxy S8/S8+version of the National Travel Agency is maintained at 257MHz most of the time, and even the extreme frequency of Rapide 3, which has always squeezed GPUs, is only 414MHz. This reflects that the Galaxy S8/S8+is not only very smooth in large games, but also only warm hand level, which is good news for the popularity and endurance of the game.
Storage performance test
All S8/S8+here are 64G, S7 edge is 32G, one plus 3T and glory V9 is 128G. In flash memory test, the larger the general capacity, the faster the speed. However, in actual performance, the Galaxy S8/S8+continues to read and write wildly. Even though its capacity is only 64G, it still beats the glory V9 and one plus 3T. Unfortunately, Snapdragon 835 is still weaker than Exynos 8895. The random read and write performance, It will directly affect the application opening speed, In addition to the performance of Glory V9, the double version S8+is better than the national bank S8, and the specific reason is unknown.
Core scheduling&heating
The Snapdragon 835 on the Galaxy S8/S8+is originally a reduced frequency version. The maximum main frequency has been reduced from 2.45G to 2.36G. With the support of the 10nm process, it is one of the few SoCs that can operate at the "highest frequency" for a long time.
Frequency monitoring during copying (left S8, right S8+)
15 minute copy output record (left S8, right S8+)
The daily application of Galaxy S8/S8+can basically be started and run at full frequency with 8-core full open. After 30 minutes of NBA2K15/Rapids 3, the copier can also run at full frequency for a long time, but there will be a period of small frequency reduction every other time. The 8-core full open copier has no obvious performance degradation for 15 minutes, which is amazing. This is one of the few flagship cores that have been available for real price and theoretical performance for many years.
In addition, the heat during the game is not high, only warm hand level, only when the brightness is the highest and the toaster is added, it can reach the hot hand level. Because ordinary large-scale games and games that squeeze GPUs are not enough for Snapdragon 835, the temperature measured in our usual game heat test is low. The room temperature is 26 degrees. After 25 minutes of running the rapids, the maximum temperature of S8+is only 36.6 degrees; The highest temperature of S8 running NBA 2K15 is only 34.4 degrees, which is amazing.
Galaxy S8/S8+photo contrast
In terms of photography, although the camera sensor on the Galaxy S8/S8+has changed from the previous generation IMX260/S5K2L1 to IMX333/S5K2L2, As the press conference said, this time the focus is not on hardware, but software upgrading. The camera parameter is still 1/2.55, 1.4 μ m unit pixel, dual core focusing, F1.7 aperture.
The four BOC Galaxy S8/S8+we got this time are all Sony's IMX333 sensors, while the European version G950F/G955F tested last time is S5K2L2. It is unknown whether the processor and sensor will be cross mixed like the previous year.
The interface of the Galaxy S8/S8+camera of the Bank of China version is simpler than that of the previous generation. The left and right sliding are respectively mode switching and various photo decorations/filters/watermarks. It has to be said that this half screen display and photo decoration are quite grounded. In addition, it also adds the shutter button to slide left and right to zoom, and slide up and down to switch the settings of front and rear cameras.
Photo experience: The camera completion of the Bank of China engineering machine is lower than that of the international version (8895), The overall photo taking experience is worse than that of the international version and the previous generation . First, its camera's fast start and hot start speed are both faster than 8890 version S7 edge is slow, and The noise of weak light shooting should also be more obvious. Although the focus of the current BOC engineering machine is still fast and the film rate is very high, the film speed is slower than that of the 8890 S7 edge. This gap will become more obvious when the light becomes worse and the night scene algorithm such as multi frame synthesis is triggered.

In terms of the film effect, we have updated the firmware of the Bank of China version S8. The two machines are slightly different in light measurement, but the overall difference is not significant.

In comparison with the S7 edge, iPhone 7 Plus and Huawei P10, the Bank of China version, like the international version, has significantly improved in glare control, white balance and noise reduction daubing. The white balance of the light scene is not as obvious as the red and warm noise of the previous generation.
The national bank version S8 with IMX333 not only has cleaner noise spots than the previous generation, but also has the same overall analytical power as the international version with S5K2L2, which can slightly beat the S7 edge. The gap between P10 and iPhone 7 has been further widened. As a representative of China, P10 still has much to improve in its photography.
Endurance and charging
Because of the Galaxy Note7 accident last year, Samsung suddenly became very cautious about the battery. The battery of the Galaxy S8/S8+has shrunk to 3000 and 3500 mAh, respectively, and the capacity is smaller than the S7 edge of the 5.5 inch screen. When the screen area of Galaxy S8/S8+is converted to 16:9 screen, it corresponds to 5.57 inches and 5.95 inches respectively. Although there is the blessing of 10nm process SoC, the screen area of both machines has become larger, which makes people worry about their endurance.
After you turn on full resolution rendering, After 30 minutes of large-scale games (NBA 2K15), 30 minutes of wifi and 4G Internet access, and 30 minutes of local video playback, a total of 2 hours of high-intensity endurance testing, the remaining power of the Galaxy S8/S8+is 83%, and the extra power of the big machine is just eaten up by the growth of the screen. This achievement is not only better than that of the previous generation, but also better than that of competitors with 4000mAh battery level. We have to sigh again that 10nm Dafa is good. It should be noted that this is only a two-hour test. If the time continues to extend, the gap will be further widened.
Last year's Snapdragon 820/821 has let the Android flagship crush the iPhone 7 Plus collectively, while this year's Snapdragon 835 is expected to make a large wave of flagship carriers run farther and farther in terms of endurance.
Although there is no need to worry about the endurance, the Galaxy S8/S8+still maintains the 9V/1.67A charging head for many years. The previous message shows that the Galaxy S8/S8+is probably equipped with the TA200 charging head of Note7. In front of the Android flagship, which is now prone to more than 24W, this charging power is indeed a lost opportunity.
In terms of actual power, we used the original 9V/1.67A (15W, S7 edge) AFC fast charging head, the highest power 25W fast charging head (on the Samsung Galaxy TabPro S panel) and the 18W output PD standard fast charging head (Pixel XL) to test, and the test power was below 10%. Results The charging power of Galaxy S8/S8+is maintained at about 12W. One S8, which uses the firmware from March, has a charging power of about 10W.
For comparison, the peak power of S7 edge charging can reach 14-15W, while the peak power of Note7 can even reach 20W. However, even if the Galaxy S8/S8+keeps charging at 12W and the battery is only 3000mAh, the charging speed of the machine is not optimistic. Samsung's charging power this time is obviously too conservative. I hope that the power limit can be relaxed when the firmware is later released and shipped officially.
summary
As the defending champion in the first half of 2017, the performance of Galaxy S8/S8+is truly remarkable:
In terms of appearance, the shocking ultra-high screen accounts for the curved round corner screen, the top workmanship, and the dust and water resistance that are still maintained are all impeccable;
The longer and narrower screen has better single hand operability, without too many false touch and compatibility problems. Some games can also be used as "cheating tools";
Although photographing is only a small improvement by squeezing toothpaste, the focusing performance and weak light imaging are still difficult to compete;
Snapdragon 835 failed to open the gap with Kirin960 in terms of CPU performance, and it still lost a little to Exynos 8895. Although the GPU performance of the previous generation is rolled, it has no advantages over the same generation;
In the case of shrinking battery, the endurance can be improved, and the dividend of 10nm process is huge.
The situation of Galaxy S8/S8+this year is very similar to the S7 edge of the previous year, and even can be directly applied to the conclusion of the previous year: unlike other brands of mobile phones, Samsung Galaxy S8/S8+has been partially lowered because of Snapdragon 835, which is the gap between the manufacturers standing at the top of Android all the year round and other manufacturers. There is no doubt that it is the real Android king in active service, and even the word "Android" can be omitted. Its rival may be the Exynos 8895 version itself.
