0

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.
