For Snapdragon 8 and Snapdragon 888, touching the conscience said that whether as a consumer or as a digital practitioner, in fact, can not be considered too satisfied, the reason everyone understands. Tuned well, we can say a mobile phone manufacturer skill, this punch ten years of kung fu, Qualcomm it can not stand; poor optimization, that can also be thrown to Qualcomm or Samsung's 5nm process, do not have to have any psychological burden.
Anyway, it's Qualcomm's fault, and everyone thinks so.
MediaTek's flagship chip was struggling under Qualcomm's step-by-step in the past, and once it could only find a sense of presence in the low-end market. If Qualcomm can remain strong, It is indeed difficult for MediaTek to achieve a breakthrough in the high-end market, but the Snapdragon 888 and Snapdragon 8 give MediaTek the opportunity to reinvigorate.
I believe that from the second half of 2021, many friends have paid attention to mediatek's engineering machines in advance "public appearance", and have achieved consistent praise on the two high-end chips of Tianji 9000 and Tianji 8100, especially in the case that MediaTek Engineering Machine has no heat dissipation, performance release and energy efficiency performance exceeds Snapdragon 8, which inevitably makes people look forward to it more and more. The originally calm lake has become "magnificent" because of the addition of MediaTek, which is beneficial and harmless to consumers.
This time, we also got two new machines of the Redmi K50 series at the first time, namely the Redmi K50 equipped with the Tianji 8100 and the Redmi K50 Pro equipped with the Tianji 9000. Honestly, we're also curious about the performance release of the Tianji 8100 and Tianji 9000, and how stable it can be with the better heat dissipation of Redmi.
In particular, the Tianji 8100 debuted by Redmi K50 will be the mainstay of this year's flagship/mid-range market, and it is also the model that most consumers will give priority to when purchasing. If you want to see the specific performance of K50 Pro and Tianji 9000, you can move to another review.
Qualcomm, don't look for me, I'm afraid MediaTek will misunderstand
Let's go straight to the theme, performance this hard dish for everyone first. First of all, the conclusion, comprehensive peak performance, temperature, power consumption data, Tianji 8100 will be the sub-flagship / mid-end market deserved king. Even in the author's opinion, if you don't necessarily require the top performance, the Tianji 8100 is even worth it compared to the Snapdragon 8.
Tianji 8100 chip and qualcomm flagship chip in recent years is different, did not use 1 + 3 + 4 three-cluster architecture, but directly used 4 Cortex A78 large cores, and the main frequency is given to 2.85GHz, it seems that MediaTek is more confident in TSMC's process, and the four big cores will not have a problem. The small core is 4 Cortex A55s at 2.0GHz. The GPU side is the G610MC6, which is also upgraded on the previous GPU architecture.
First use AnTutu to run an overall "impression score" for everyone, the overall score in the performance mode (the same below) is 809584 points, which is comparable to the Snapdragon 870 after optimization in the second half of last year, and it is fast catching up with the level of Snapdragon 888, and the GPU part is not left behind.
The CPU part is still tested with GeekBench 5.4.1, and the single-core performance is relatively poor because it does not use the three-bush architecture this time, which is about the single-core level of the Snapdragon 865. The score of nearly 3700 points on the multi-core is similar to the score of snapdragon 8 under the software test version. In the case of four big nuclei letting go of the run, the Tianji 8100 did have a good performance.
The GPU part is the one that surprises us the most. The peak performance is 5755 points, which is comparable to the Snapdragon 870 and close to the level of the Snapdragon 888. However, the stability data below is a high level that we have not tested at present, and 92.7% means that in most scenarios, the Tianji 8100 will not have a significant performance decline.
3D Mark Wild Life Stress Test is a high-voltage test that lasts for 20 minutes, most flagship models can only achieve 50%-70% stability in this link, and are basically in the frequency reduction stage in the middle and late stages, while the Tianji 8100 can maintain a stable output for a long time, which is really surprising.
But as we have mentioned many times in the test before, it is not uncommon to have a good experience of running scores but "pulling the crotch", all the hardware of the mobile phone is for the experience, and the parameters are not as good as the experience of excellent results. So we still look at the actual performance in the game. The phone maintains automatic brightness, turns on Bluetooth and WLAN connections, and clears the background.
In high quality, the average frame rate of "Original God" is 51fps, which seems to be lower than the data of some Snapdragon 8 Gen1 models? But in fact, it can be used to compare The Snapdragon 8 with the Tianji 8100 itself is successful, and the Tianji 8100 also has its own advantages, such as the Tianji 8100 has almost no frequency reduction throughout the process, the frame rate map you see the number of frames drops, there is almost no stutter problem, and the frame rate drop is limited to some scenes that require strong CPU and rendering performance.
And even if the frame rate is compared, in the case of not using external means, the Snapdragon 8 model is only close to the level of the Redmi K50 in addition to a certain model that lets go of the performance, and the consequence of letting go of the run is that the fuselage temperature reaches about 50 ° C. I listed the high-quality "Original God" test results of several Snapdragon 8 flagships here, which can be compared. In order to avoid suspicion, there is no specific model.
(A snapdragon 8 flagship with a body temperature of 50 °C)
(Two other Snapdragon 8 flagships)
In fact, users familiar with "Original God" should know that the GPU of this game is not a bottleneck, the CPU is. At present, perfdog can not read the GPU usage rate of MediaTek chips, in the test of snapdragon 8 models, GPU usage rate is often only 60%-70%, and the game will be because of the CPU downscaling frame rate plunged sharply, Tianji 8100 should also be difficult to touch the GPU bottleneck. Looking at the performance of Tianji 8100, three of the four large nuclei have remained running at 2.3GHz for a long time, and when there are few frequency fluctuations, it is 4 small nuclei and 1 large core to top.
It is worth mentioning that the 4 small cores also run at high frequencies of 2.0GHz for a long time. In the past, we always ridiculed mediatek chip is a core difficult, seven core onlookers, but now it can do a collective effort, for the "Original God" such a multi-core optimization of the game, the experience is a great improvement.
At present, we simply read the data through the software, and the average power consumption of the high-quality "Original God" is about 5.5W, and the peak can reach 7.6W, which is probably one of the best performances on the current mobile phone products. From the side, it is not also explained that TSMC's process is indeed much more mature...
Therefore, a good chip is easy to bring about a virtuous circle. We have seen that the Redmi K50 is not only excellent in stability, excellent gaming experience, greatly improved energy efficiency ratio, but also gives users a very comfortable grip in terms of body temperature. Chongqing's recent warmer weather, the outdoor temperature in the afternoon has reached 31 ° C, the indoor temperature shows 30 ° C, but the somatosensory should only be about 28 ° C. In such an environment to test the "Original God" for half an hour, the body temperature of the Redmi K50 is only 43.5 ° C and 42.8 ° C on the front and back, and in the common holding habit, basically only the fingers of the left hand used to support the fuselage will feel a little heat.
Of course, Tianji 8100 is not a flagship chip in the strict sense, the sub-flagship, the mid-end market is where it shines, in a sense, we also use the price of mid-range products to experience better game performance than the flagship. Then we don't have to use flagship game standards to require the redmi K50 game experience, we will reduce "Original God" to medium quality, other conditions remain unchanged, Liyue City continues to run for half an hour, and the frame rate is as follows.
The average frame rate is higher, the frame rate fluctuation is smaller, and the frame rate shows a relatively regular periodic change, which means that the K50 does not have any performance degradation due to temperature changes. In the test, we deliberately paid attention to the relationship between the game screen and the frame rate, and the distance between the two teleportation points in Liyue City has a certain fluctuation due to the building and light and shadow, and the frame rate will stabilize in other positions, about 55-58fps. In the actual game process, players can choose to turn off some of the light and shadow effects to improve the overall stability of the game.
Compared with the high image quality, the power consumption is further reduced, only less than 5.4W, and the energy efficiency advantage of the Tianji 8100 is still relatively obvious.
In "Glory of the King", open the 120 frame mode, the highest resolution, high quality HD, synchronously open anti-aliasing and water reflection, simple matching, the frame rate is no jitter throughout the whole process, maintain 120fps full frame, stable effect pull full.
Tianji 8100 is positioned in the sub-flagship, if placed on this year's Qualcomm chip, that is the competitor of Snapdragon 888 and Snapdragon 870. Of course, we see that the performance of the Tianji 8100 on the Redmi K50 is obviously slightly better, perhaps not as good as the Snapdragon 888 in peak performance, but surpassing the Snapdragon 870 is not a problem. What is more outstanding is that the Tianji 8100 achieves a stable performance output at low power consumption, and the stability is not available in the Snapdragon 888.
For gamers, Tianji 8100 is the strongest chip in this gear.
It may be the 5G phone with the strongest battery life
After the release of the iPhone 13 Pro Max last year, everyone was surprised to find that the flagship with the strongest endurance in the conventional form of mobile phones has been taken down by Apple. Today, with a large battery of 5500mAh and the low power consumption of Tianji 8100, Redmi K50 will become the king of a new generation of battery life.
Like the iPhone 13 Pro Max we tested, we used the 5G network to play 1080p TV series online, the phone maintained the highest brightness and maximum volume, the refresh rate was smart, the resolution was intelligently adjusted at 2K, and the playback from 100% power to shutdown was recorded. 580 minutes, which is the final result of the K50, is 1 hour higher than the 517 minutes of the iPhone 13 Pro Max, which should be the strongest battery life at present.
In terms of fast charging, The Redmi K50 supports 67W fast charging, but because the battery capacity is 5500mAh, the corresponding charging time will be longer. Charging starts at 1% and takes 60 minutes to fully charge, but at 60 minutes the galvanometer has almost no current input and can be judged to be fully charged. The first 15 minutes can be charged to 42%, the efficiency is not bad.
I can already anticipate what kind of compliments users of the Redmi K50 will have: two days a charge, a full day of playing games... Stronger battery life can effectively improve the continuous use experience of the phone, and more possibilities will be unlocked in outdoor scenes.
This screen, very strong
In terms of design style, K50 has a heritage and changes compared to the previous generation of products. For example, the ink feather color we got continues the cosmic aesthetic design inspiration of the previous generation of products, and is full of the depth of the starry sky. At the same time, K50 also added a little design to the camera module, and the collision between Founder and Round seems to add the concept of "Heavenly Round Place", which is China's thinking and exploration of the universe. The decorative rings in the style of the star ring around the lens further enhance the texture of the black and bring a more holistic visual appearance.
The change is in the texture. The texture of the ink feathers of the previous generation comes from the Damascus steel knife, which is a more metallic color. On the K50 ink feather color matching, the texture from the olive meteorite from outer space is absorbed, polished by the nano-microcrystalline process, irregular changes in the grain and faint color gradients, and the mysterious beauty of the starry sky.
The screen upgrade on the front is probably the strongest screen ever recorded in the K series "Standard Edition". This screen specification is very high, 6.67 inches size, resolution 3200 * 1440, refresh rate support to 120Hz, from Samsung flexible screen, and is still a straight screen, in the same positioning model, this is almost the highest specification of the screen.
At the same time, this screen supports full DC dimming to effectively reduce the strobe problem, support 16,000 levels of automatic brightness adjustment, and cooperate with the light sensor to achieve more accurate automatic brightness adjustment. Peak brightness can reach 1200nit, so support for Dolby Vision makes sense, with more highlight and shadow detail when playing HDR 10+ high dynamic range video.
In terms of experience, the upgrade brought by this screen is obvious. As a device that needs to interact through the screen most of the time, especially the dependence of modern people on mobile phones is infinitely high, long-term use of mobile phone screen quality, health has extremely high requirements. The K50 uses a high-specification 2K flexible direct screen to give users the best feedback.
The most eye-catching aspect of the fuselage opening is the dual speakers at the top and bottom of the fuselage, which are staggered left and right. Stereo dual speakers can be a wonderful upgrade for heavy users of the phone, which can greatly improve the sound effect of the phone in multiple scenes, without relying on the effect of headphones. At the same time, the K50 earpiece can also emit sound outwards, making the sound of the mobile phone more three-dimensional.
2K+120Hz direct screen in the consumer group has been high in the voice, but similar products have been few, Redmi K50 is undoubtedly a very good appetite for people's sub-flagship new products.
Experience, very detailed
It has to be said that as a light flagship positioning model, although the K50 can not do the best in all aspects, but also has an excellent level. For example, the image performance, the rear uses 48 million pixels three shots, the sample during the day is full of color, the details are restored in place, whether it is indoors or outdoors can take good photos.
Night scenes can also suppress the highlights relatively well, and improve the details of the shadows, you can see a small amount of trees leaking from distant buildings. Noise is well controlled and is a good look at a glance.
There are also Dolby dual speakers. When it comes to speakers, many people will think of subways, elevators, vibrato, but in fact, there are many scenes where it is not very convenient to use headphones, such as when playing games, or watching movies with a mobile phone at home, at this time it is not appropriate to wear headphones, right? The K50 is a solid stereoscopic dual speaker, and supports Dolbyu Atmos, and the earpiece at the top can also assist in sound, bringing more three-dimensional business effects, chasing dramas and playing games more immersive.
The X-axis linear motor can be said to be the necessary hardware for Redmi, and even the high-end models in the entire Xiaomi ecosystem, which effectively improves the vibration feedback of the mobile phone, and the information prompt, typing, and game vibration can give a more comfortable effect. There are also full-featured NFC and infrared, without these two are embarrassed to call Redmi mobile phones, this is to start from the details of the experience.
Review summary
There are many highlights of the Redmi K50, such as the 2K flexible direct screen, which is a very competitive hardware on the same price point products, and the display effect is also first-class. But maybe you are also like me, more focus on the Tianji 8100 chip, the better peak performance, and the long-term stable performance release, countless users who are tortured by the "fire dragon" can't help but cry: this is the ultimate experience I want to see.
The stability of the Tianji 8100 in the 3D Mark and the game testing of "Original God" is obvious to all. Leading process, excellent performance scheduling, and K50's 3950mm super VC cooling are the keys to maintaining a stable gaming experience.
The first launch of the Tianji 8100, this is the biggest killer of the Redmi K50.
