This is the first high-end notebook product in the history of RedmiBook. A notebook computer has no shortcomings in screen, hard disk, memory, and lightness. It can be called a milestone in the history of RedmiBook. Today’s protagonist is its fellow junior RedmiBook Pro 14!
The biggest feature of the RedmiBook Pro 15 is that it is equipped with Intel’s eleventh generation Core high-performance version i5-11350H processor. The difference between RedmiBook Pro 14 is that it is equipped with a low-power version of the i5 that belongs to the eleventh generation Core family -an 1135G7 processor.
So, how strong is this generation compared to the tenth-generation Core i5-10210U equipped with the previous RedmiBook 14? Let’s first look at the following table:
Compared with i5-10210U, the new generation i5-1135G7 uses Intel 10nm process technology. Although it is also 4 cores and 8 threads, the number of secondary caches has increased from 1MB to 5MB, which is exactly 5 times, and the tertiary cache has also increased from 6MB. To 8MB, equivalent to the level of the previous generation i7. The large increase in cache is an important factor for the 20% increase in IPC of the Tiger Lake architecture. Even if the core frequency is slightly reduced, the performance of the i5-1135G7 will be far stronger than the i5-10210U processor.
In addition, the built-in Iris Xe nuclear display of i5-1135G7 has 80 groups of EU, and the frequency is as high as 1.3GHz. The UHD630 nuclear display on the i5-10210U has only 24 groups of EU, and the frequency is only 1.15G. Therefore, in terms of nuclear display performance, i5-1135G7 will be several times the performance of i5-10210U and can be comparable to entry-level standalone displays like GeForce MX250.
Let’s talk about the Tiger Lake-U 11th generation Core platform. In addition to the performance improvement, the AVX512 instruction set and AI acceleration are also highlights that cannot be ignored. If AI has increasingly penetrated work and life, Tiger Lake is a processor born for AI. Its built-in Iris XE GPU, AVX 512 instruction set, and GNA neural accelerator all have AI acceleration functions. The computing power provided by these three engines can perfectly support various AI reasoning scenarios.
Thanks to the addition of the AVX512 instruction set, the i5-1135G7 processor has twice the 256-bit vector processing capability compared to mainstream products and competing AVX2. In addition, VNNI, based on the AVX512 instruction set, is Intel’s latest AI inference acceleration instruction set. Turning the three instructions required for the original int8 fusion multiplication and addition operation into one instruction execution greatly improves the AI convolution calculation related to the int8 data type. The rate of inference applications.
With the support of powerful AI computing power, PC can easily realize intelligent recognition and real-time optimization, one-click cutout, beauty and background replacement in graphics creation. In the video processing process, intelligent scene recognition, intelligent resolution enhancement (similar to DLSS), picture coloring, style change, intelligent recognition of main action areas, automatic execution of cropping, horizontal version to vertical version, etc., after the intervention of AI, Not only can the creative efficiency be greatly improved, the quality of the works can also be guaranteed.
In terms of live video and remote meetings, powerful AI computing power can achieve a smooth and clear interactive experience at the hardware level, intelligently distinguish human voices and portraits, and achieve high-quality noise cancellation, resolution enhancement, background blur, and other functions. In addition, the Tiger Lake-U platform also supports Thunderbolt 4 and Wi-Fi 6 high-speed connections, which is of great benefit to extended use. Both of these points have also landed on RedmiBook Pro 14, which is quite pleasant.
The highest speed of Thunderbolt 4 is 40Gbps like the previous generation, but it is still eight times that of USB 3.1 Gen2, and its scalability and functionality are greatly enhanced. For example, it can be connected to dual 4Kor single 8K high-definition displays, such as fast charging.
The detailed configuration table of the RedmiBook Pro 14 notebook is as follows:
Design & Appearance
RedmiBook Pro 14 is made with a micron-level CNC integrated fine carving process, and the entire A-side and C side with sidewalls are all finely carved from a single piece of the metal ingot. In addition, there is a ceramic sandblasting metal anodizing process on the surface of the notebook, so the notebook feels delicate to the touch. 14.1-inch IPS screen, 16:10 ratio, can display more content vertically, which can improve office efficiency.
The screen resolution is up to 2560*1600, with a 100% sRGB color gamut. C side is a traditional full-size keyboard with integrated molding design, humanized layout, 19.5mm key pitch standard, 1.5mm comfortable rebound high keystroke. There is a certification sticker in the middle of the D side, and there is a row of heat dissipation grids on it.

4. World of Tanks
The score of RedmiBook Pro 14 in “World of Tanks” is 8641, which translates to a frame rate of 52FPS. Five, baking machine and battery life test: PCMark measured nearly 10 hours of battery life
1. Endurance test
The RedmiBook Pro 14 notebook has a built-in large-capacity lithium battery with a capacity of 56Wh. We use PCMark 10 actually to test the battery life of the notebook.
The selected scene for the test is a modern office with PCMark 10, the power mode is “energy-saving mode”, all other processes are closed during the test, the network connection is closed, and the screen brightness is adjusted to 50%.
In the PCMark 10 modern office environment, the battery life test score is 9 hours and 45 minutes. Compared with today’s thin and light notebooks, this score is not very outstanding, but it is enough to support the needs of one day of mobile office battery life.
2. CPU baking machine test
Use AIDA64 FPU for the baking machine test, and the room temperature is 26 degrees during the test.
At the beginning of the baking machine, the power consumption of the i5-1135G7 was as high as 35W, but it will gradually decrease afterward and finally stabilized at about 29W. This is still the case even if you continue to bake for 15 minutes. The processor’s temperature during the baking machine is 93 degrees, and the full-core frequency is 3.2GHz.
Intel’s 11th generation low-power Core Duo is undisputedly a single-core processor with a solid performance in the notebook field. Comparable to the single-core performance of the top desktop processor, with fast response capability, whether it is the startup speed of the application or the computing speed of the office software, it is far from the previous low-power processors.
For example, compared with the i5-10210U equipped with the previous RedmiBook 14, the single-core performance of the i5-1135G7 processor of the RedmiBook Pro 14 has increased about 19%, and the multi-core performance has increased by more than 50%. Of course, the improvement of multi-core performance is beyond Tiger Lake’s IPC progress. RedmiBook Pro14 provides 28W TDP, which is also one of the important factors for performance improvement.
The Iris Xe GPU also allows Intel to change the old look in terms of nuclear display completely. The i5-1135G7 processor with 80 groups has a core display performance comparable to that of an independent display such as the GeForce MX250. Games such as “League of Legends”, “World of Tanks”, and “Overwatch” can be very good at medium and high quality. Smooth gaming experience.
These changes in numbers, reflected in practical applications, are a leap in real user experience. Today’s thin and light notebooks basically have the strength of an all-around notebook. Whether it is a daily multi-tasking office or a variety of audio-visual entertainment, even moderate content creation, casual games, it is no longer a problem. Don’t worry about running the software, but also greatly promote. With the advancement of the mobile era, there is no need to rely on desktop computers for a little heavy task.
Of course, the upgrade of the RedmiBook Pro 14 is much more than that of the 11th generation Core. The 2560*1600 resolution high color gamut screen, 65W PD charger, dual-channel DDR4 3200MHz memory, NVMe SSD, and other equipment make Redmi a 14-inch notebook with no obvious shortcomings.
In addition, in terms of battery life, with the support of the 10nm process i5-1135G7 processor, RedmiBook Pro 14 measured nearly 10 hours of battery life in PCMark 10, and there is no big problem with the normal use of mobile office support for 1 to 2 days.
