What does redmibook mean? What brand of notebook (Redmi notebook pro 15 configuration parameters)

Redmibook is a notebook series of Redmi owned by Xiaomi. Today's notebook market has entered the era of crazy nei and juan. The game is light and thin, light and thin, high performance and family commercialization. Various games with blurred boundaries emerge one after another, the purpose of which is nothing more than enriching the user portraits of products.

With the performance-to-power ratio of processors, graphics cards and other hardware getting higher and higher, thin design plays an increasingly important role. At this juncture when the processor and graphics card are changing from old to new, Redmi holds high quot; thin and high performance quot;, and it is not surprising that Redmi Book Pro 15 2022 was launched. Judging from our current testing experience, it is indeed a wolf suit in sheep's clothing.

Large core has high performance and small core has long battery life.

That's right. Redmi Book Pro 15 2022 is Intel's 12 generation H45 processor. We got the flagship version of Core i7 12650H, followed by the version of Core i5 12450H. Core i7 12650H adopts Intel 3rd generation 10nm process. However, Intel defines it as "Intel 7 processor", which is a 7-nanometer processor of the same generation as TSMC.

The biggest change of 12 generation core is the adoption of mixed architecture design, which is familiar to Android and Apple players. Core i7 12650H adopts a combination of six performance cores supporting multithreading and four efficiency cores, with a total of *** 10 cores and 16 threads. The performance core runs at 2.3~4.7GHz, the efficiency core runs at 1.7~3.5GHz, and the design TDP is 45W.

Compared with the previous generation tribal tiger H45 processor, 12 generation H45 has more physical cores. Even with 16 threads, the performance of Core i7 12650H is better than that of the previous generation Core i7 1 1800H. The multithreading performance of CineBench R23 has exceeded 13400, which is nearly 9% higher than the previous generation. This means that it has advantages in programming, office applications, graphic design and other fields.

Of course, this is the result of Redmi Book Pro 15 2022 switching to speed mode through Fn K shortcut key. At present, most domestic brand notebooks have the function of switching performance modes, so don't forget to switch on and off as needed before use, otherwise it is likely to affect work efficiency.

In addition, the single-core performance of Core i7 12650H is greatly improved, and CineBench R23 breaks through 1700, far better than Core i7 1 1800H. Considering that the current 3A games only support six cores, it is not difficult to find that the processor utilization rate is only 20~30% when testing most games, so the number of cores is small, especially the performance of single core has a great influence on the game.

Common notebook testing often focuses on the pure performance ceiling, but in real life, we rarely encounter the situation that the processor graphics card is full, especially for thin and light users, and we need it. The biggest advantage of large and small cores is that they can sprint by performance cores or maintain battery life by efficiency cores.

In mute mode, networking, 50% brightness and volume, local 1080P video is provided by Windows 1 1 # 039 American Film and Television. Many times, the four efficiency cores act as the main force of the operating system. Local video playback is about 1 hour. Occasionally, when chatting on WeChat, the battery is reduced from 72Wh to 62Wh, and Redmi Book Pro 15 2022 can last for more than 6 hours after daily light use.

RTX 2050!

I must admit, when I first got Redmi Book Pro 15 2022, all I could think of was quotRTX 2050? Is there a mistake? But in fact, RTX 2050 is a new graphics card released only at the end of last year. Although this stage belongs to RTX 20 series, it does not use the common12nmtu106quot turing quot micro-architecture of RTX 20 series, but uses the same 8nm ga107quot ample quot micro-architecture as RTX 30 series, with 2048 shader units as standard.

It seems to be better here than RTX 2060, but how can Lao Huang's watermelon knife tolerate this quot intrusion quot incident? Therefore, RTX 2050 experienced a terrible degradation: the memory bit width was cut to 64 bits, that is to say, although it was running at the same memory frequency, the memory throughput of RTX 2050 was 1/3 of that of RTX 2060, the memory capacity was reduced to 4GB, the power consumption was limited to below 45 W ... The performance was far worse than that of RTX 2060, and the real positioning was slightly higher than that of GTX/.

But as an old saying goes. A thin camel is bigger than a horse. After all, RTX 2050 supports ray tracing and DLSS, especially the latter. By reducing the actual rendering resolution and then using the data of deep learning to enlarge the picture, the hardware overhead is greatly reduced while ensuring the image quality and improving the frame rate of the game.

Take "God of War" as an example, the actual rendering resolution of DLSS with the highest performance is only 1068668, but it can be guaranteed to run on the 32002000 resolution display of Redmi Book Pro 15 2022, with low special effects of nearly 60fps, and the picture quality looks completely acceptable.

Another latest 3A masterpiece, Cyberpunk 2077, uses "super performance" and turns on low special effects in DLSS. Even forza motorsport: Horizon 5, which doesn't support DLSS at present, can reach 58fps on average with low special effects and manual ray tracing, which RTX 1650 without DLSS and ray tracing can't do.

Don't forget, we can further reduce the output resolution to run. After all, the screen spacing of 15.6 inch is already very small, even if it is reduced to 1920 1200, it is enough to see. It should be noted that starting DLSS will increase the load of the processor, but it is not a big deal for Redmi Book Pro 15 2022, which has strong processor performance. You can safely open it.

Of course, in the price range of 6000~7000, Redmi Book Pro 15 2022 mainly faces RTX 3050, whose graphics card performance is undoubtedly better. The difference at the product end is that the performance of Redmi Book Pro 15 2022 is improved on the basis of light and thin design, so even if it is 15.6 inch/KLOC-0 1.77kg, it still has a large-capacity battery of 72Wh, and Redmi Book Pro 15 2022 uses 130W.

On the other hand, competitors often choose to sacrifice battery capacity, such as choosing a battery within 50Wh, whether it is a heavy traditional game book or changing the thin design based on the game book thinking. However, the upper limits of performance and power consumption are higher and the interfaces are richer, so strictly speaking, their design ideas are not completely coincident.

As for the shortcomings, it is still less than-,and there is no direct display. To this end, we conducted a comparative test. When the monitor is directly output to an external monitor, the number of game frames will increase by 5~ 10%. However, considering that the frame rate base of 3A games is not large, this difference will not actually lead to a qualitative difference. Although e-sports games such as League of Legends have considerable differences in frame rate, they are beyond most people's perception.

I think direct display is the icing on the cake. It is better to have it, but it won without serious consequences. T on the other hand, due to the consideration of power consumption, the commercial books on the market are not directly connected, and even not all models of game books are directly connected.

Performance releases courage and warmth.

Although it is positioned as a high-performance lightweight book, the performance release strategy of Redmi Book Pro 15 2022 is actually quite similar to that of the game book. Never flinch when baking the processor alone, even if it reaches 97. Core i7 12650H processor can always run at 55W.

When baking dual processors and graphics cards, the processor will return to 20~30W, and the frequency will be greatly reduced. The cooling strategy is to give priority to ensuring that RTX 2050 graphics card runs at full speed of 45W, at which time neither the processor nor the graphics card will exceed 80W. In the game, because the real processor and graphics card will not be fully loaded at the same time and will not trigger the temperature wall limit, the comprehensive power consumption can reach or even exceed 80W, which is quite good.

Even though Redmi Book Pro 15 2022 adopts the design of double fans and three heat pipes, there is no multi-sided air outlet design because the performance release strategy is fierce and there is only one off-screen air outlet.

After playing the game for 20 minutes, we measured the temperature of the keyboard surface with infrared rays. We can see that in the middle of the keyboard, the temperature near the G, H and J keys has reached 58.3, which also corresponds to the area where the processor and graphics card are located. There is also a temperature above 43 near the W, A, S and D keys. It is not recommended that you play games with the keyboard and mouse for a long time. Anyway, most 3A are platforms now. In addition to shooting games, the handle is the first choice, and winning again will not affect me.

Redmi Book Pro 15 2022 is also equipped with 16GB LPDDR5 5200MHz dual-channel memory. When the bandwidth is upgraded, the power consumption is also greatly reduced. Because it is on-board memory, it can't be upgraded, but this capacity is barely enough to connect 3A games or video clips.

In terms of storage, it is 5 12GB PCIe 4.0 SSD, which reads and writes 3.4GB/s and 2.7GB/s in measured sequence, and reads and writes 70MB/s and197mb/s randomly in 4K. The software startup response is also very fast, and the game reading does not need a long waiting time. But to be honest, this achievement is still relatively general for PCIe 4.0 SSD, especially for 4K random reading and writing, which is basically the level of PCIe 3.0.

The default capacity allocation of drive C is 146GB, and the rest is drive D. This allocation can make drive D hold at least 2~3 3A masterpieces, and drive C also has enough space to store data. It should be noted that SSD is a single-socket design, which can only be replaced and cannot be directly upgraded. If you have the ability to be anxious, you'd better plan ahead.

3.2K high-resolution screen, all-metal body, cross-screen interconnection.

It is the biggest highlight of Redmi Book Pro 15 2022 screen besides performance. It follows the previous generation's 16: 10 32002000 resolution screen, which is quite rare. It has only one screen.
