Gearbest Tech
[Gearbest Review]A few years ago, the concept of thin and light performance laptops had just emerged, and there were not many products to choose from on the market. Xiaomi Notebook Pro GTX version is one of the few, with a 15.6-inch screen, a compact aluminum alloy body, and a GTX1050 Max-Q graphics card with good performance and power consumption, so I didn't replace it for a long time.
At a time when process technology and CPU/GPU architecture are constantly innovating, AMD's Ryzen processors seem to have given consumers a brand new answer – your core graphics card can be just as powerful. The newly released Redmi Book Pro 15 2023 Ryzen Edition is obviously such a product. As a replacement product, its sincerity is far more than just replacing the new generation of Ryzen 7040 series mobile processors.
Replaced with Ryzen 7 7840HS, Radeon 780M's most powerful core graphics card is now available
The biggest update of the Redmi Book Pro 15 2023 Ryzen Edition is that it is equipped with the Ryzen 7 7840HS processor from AMD (hereinafter referred to as R7 7840HS). In fact, HS and H do not need to be too concerned about the 7000 series Ryzen processors. Users only need to pay attention to TDP. The official TDP range of the R7 7840HS processor is 35W-54W, and the Redmi Book Pro 15 2023 Ryzen Edition chooses 54W full power consumption to release performance, which lives up to the name of “Pro”.
Let's first take a look at the core specifications of the R7 7840HS. The platform codename of this series is “Dragon Range”, which sounds quite impressive. It uses a 4nm process technology and the latest Zen 4 architecture. In the CPU part, it has 8 cores and 16 threads, a main frequency of 3.8GHz, a maximum acceleration frequency of 5.1GHz, an L2 cache of 8MB, and an L3 cache of 16MB.
The biggest highlight of this processor is the GPU part. It integrates the latest Radeon 780M core graphics card, and the architecture adopts AMD's latest RDNA 3. It has 12 computing units (12CU), and the GPU's main frequency can reach up to 2700MHz. Users familiar with AMD or APU must know that in addition to its own specifications, the core graphics card is also very dependent on the absolute performance of the memory. The Redmi Book Pro 15 2023 Ryzen version is equipped with DDR5 6400MHz memory specifications.
In terms of memory, the Redmi Book Pro 15 2023 Ryzen version continues the level of the previous generation. At present, except for a few notebook products that are equipped with memory with a frequency of more than 7000MHz, most of them will use 6400MHz or 6800MHz memory. This notebook is also above the mainstream level.
First, let's take a look at the performance release. In a double-baking test at room temperature of 23 degrees Celsius, we can see from the screenshots that the processor's function can be stabilized at 54W, and the core temperature is maintained at around 80 degrees Celsius. What satisfies me is that even under such working conditions, the fan noise is still well controlled, which is definitely a plus.
R20 test results
R23 test results
In the CPU part, we used CineBench R20 for testing, and the single-core score was 684cb, and the multi-core score was 6121cb. In the CineBench R23 test, the R7 7840HS scored 1729 points in single-core and 15042 points in multi-core. The single-core performance is comparable to that of the Core i5-13500H, and the gap with the i7-13700H is not big, which can be regarded as the same level of performance; the multi-core score is slightly higher than that of the Core i7-13700H, which is a small advance.
As for the parameters of this most powerful core graphics, we have just mentioned that, with dual-channel 6400MHz memory, we used 3D Mark to run the score, and got 3200 points in Time Spy mode (graphics score is 2859). This score is improved compared with the previous generation Radeon 680M in performance, far exceeding the core graphics performance of the Core family, and is close to the performance of the RTX2050 mobile version.
Next, we tested several games, first trying the classic “Give Him Love 5”. In the benchmark test of the game, the combination of R7 7840HS + Radeon 780M, under the parameters of 1080P high-definition, the frame rate can be stabilized at more than 62 frames. You should know that this game has always been considered an “A-black” game, and it is not easy to achieve such a result, which has reached the definition of smooth operation.
In the test of “PUBG”, under the same parameters of full high quality + 1080P, the average frame rate in the Erangel map is 48, if it is in the smaller rainforest map, it can be stable at around 60 frames, and if it is adjusted to medium quality, the average frame rate can be maintained at 80. Although PlayerUnknown's Battlegrounds is no longer popular, it is a very representative game in terms of graphics card performance. After all, it is because of it that GTX1060 has become the graphics card with the highest installation volume among Steam users.

According to the test results just now, with the full power release of R7 7840HS, the Redmi Book Pro 15 2023 Ryzen version can almost play 3A games at 1080P quality, and it deserves the title of the strongest core display. And everyone knows that these generations of Ryzen processors have done a pretty good job in energy efficiency and power consumption control. With a 72Wh battery, the battery life of the Redmi Book Pro 15 2023 Ryzen version should not be underestimated.
The screen is upgraded to 3.2K+120Hz high refresh rate and the new logo is replaced
In terms of screen, the Redmi Book Pro 15 2023 Ryzen Edition has also been upgraded. The 15.6-inch IPS screen has not changed, the resolution is still 3200*2000 pixels, and the PPI has reached 242, which is a continuation of the advantages of the previous generation. While maintaining the advantages, the refresh rate of this screen has been upgraded from 90Hz of the previous generation to 120Hz, and supports smart switching. The screen brightness has also been upgraded from 400 nits of the previous generation to 500 nits, allowing users to easily see the content on the screen even outdoors.
In addition, the color gamut of this screen reaches 100% sRGB, Delta E ≈ 0.43, and the color accuracy of the screen is further improved. This screen also supports DC dimming and has a built-in Light Sensor intelligent photosensitivity. While ensuring that the screen is flicker-free, it can also adjust the screen brightness and keyboard brightness according to the ambient light. The certification link is also not absent. This screen supports Dolby Vision + Dolby Atmos dual certification, and has passed HDR 400 certification and Rhine TV hardware low blue light certification. In other words, not only the display effect is outstanding, but also it is more secure for eye health.
In terms of the mold part, the Redmi Book Pro 15 2023 Ryzen version does not use the new mold of the new Redmi Book 14, but the logo part on the A side is replaced with a new logo. Unfortunately, it does not adopt the same three-dimensional design as the new Redmi Book 14, but is sprayed on the metal.
Although it does not use a new design style, the Redmi Book Pro 15 2023 Ryzen Edition is indeed unambiguous in the shell materials and craftsmanship. The body is made of 6-series aviation-grade aluminum alloy, which is strong, safe, corrosion-resistant and anti-oxidation. On the A and C sides of the body, the CNC integrated carving process is used, combined with the ceramic sandblasting process, so that the notebook is guaranteed in texture and feel.
Although the Redmi Book Pro 15 2023 Ryzen Edition is a 15.6-inch notebook, it does not have a numeric keypad design, which is also an old tradition. However, under the premise of the 87-key standard layout, an edit key is added to the far right. The keys support a total of 4 levels of backlight adjustment, with a 1.3 key travel and a 0.2mm deep hyperbolic groove keycap.
If you have used a Xiaomi pen or a Redmi notebook, I don't need to say much about the feel of the keyboard. The length of the key travel, the speed and strength of the key rebound are all above average. As a writer, the requirements for the keyboard are relatively high, especially for long-term typing. The Redmi Book Pro 15 2023 Ryzen version will not make me feel tired quickly. Below the keyboard is an oversized touchpad of 125mm x 81.6mm, and the sliding feel and pressing force are quite satisfactory.
In terms of interfaces, the left side of the body is equipped with USB-C 3.2 Gen2, HDMI 2.0 and 3.5mm headphone jack; the right side of the body is equipped with USB-A 3.2 Gen1, USB-C 3.2 Gen2 and SD card reader. These are consistent with the previous generation of products, ensuring the practicality of the product.
In other parts, the Redmi Book Pro 15 2023 Ryzen Edition also has some minor upgrades, such as the camera has been upgraded from 720P to 1080P, but the physical bezel still does not appear. It has been upgraded to the new Xiaomi MiShare, which supports smart interconnection of mobile phones, tablets, headphones and other devices, mobile phone mirroring, file transfer, wireless headphone interconnection and other functions, and one-click hotspot, which is very practical.
In general, after the Redmi Book Pro 15 2023 Ryzen Edition was replaced with AMD Ryzen 7 7840HS, the product strength has been significantly improved. Whether it is CPU performance, core graphics performance or energy efficiency performance, it is very good, and mainstream 3A game masterpieces can be played smoothly. And the screen specifications have also been further improved. Although it is a pity that the new mold is not used, there are indeed not many all-round notebooks that can achieve this performance at this price. The Redmi Book Pro 15 2023 Ryzen Edition has firmly grasped this market.
