Shulou(Shulou.com)11/24 Report--

The strength of mobile phone manufacturers to make thin books has always been something to be reckoned with. They can always cram some configurations and processes that do not belong to this price into lightweight books. For example, today's protagonist RedmiBook Pro 14 2022 RedmiBook Pro can use a 2.5K 120Hz screen at a price of more than 4000, and an all-metal CNC integrated body, which looks quite high-end.

RedmiBook Pro 14 2022 is also available in multiple configurations. We chose RedmiBook Pro 14 2022 Core with i5-12450H and RedmiBook Pro 14 2022 with R7-6800H. In this article, we will take a look at their advantages and disadvantages, and give suggestions for purchase.

The exterior design RedmiBook Pro 14 2022 gives people a full sense of texture, which comes from the smooth all-metal fuselage, which is about 15.9mm in thickness, but weighs as much as 1.45kg, not very light, but comfortable to hold in the hand.

Sides An and B support one-handed opening and closing, with a maximum opening and closing angle of about 130 degrees. The B side is a 2.5K 120Hz that is hard to find at this price, with a camera and stereo microphone at the top of the screen and a "Redmi" logo below. This 2560-1600 resolution screen covers 100% sRGB, making it a good screen for both gaming, office and creative production.

The whole C and D faces are also processed by CNC process, the keyboard adopts sunken design and scissors foot structure, the distance between keys and caps is large, and there are independent Xiao Ai voice assistant keys on the top of the right. The key cap is the mainstream chocolate key cap, the key range is 1.5mm, supports two levels of backlight adjustment, the overall percussion feel is regular and the feedback is moderate.

As for the touchpad, RedmiBook Pro 14 2022 has a large area and is located in the lower center of the keyboard area, making it comfortable and convenient to operate.

On the power key, RedmiBook Pro 14 2022 uses the combination of the boot key and the fingerprint identification button, which can be quickly turned on and unlocked at the touch of a button.

In terms of interface, RedmiBook Pro 14 2022 Core Edition is equipped with 1 Thunderbolt 4 interface, 1 full-function USB-C port, 1 USB-An interface, 1 HDMI2.0 port and 1 3.5mm headset port. The Ruilong version does not have Lightning 4 interface, nor does it have a USB4 interface with similar functions.

The so-called Lightning 4 is a protocol based on USB-C interface, which not only transmits as fast as 40Gbps, which is twice as fast as traditional USB3.0, but also supports external connection of two 4K or an 8K screen. The most important thing is that it can be connected to the graphics card to expand the docking station to make up for the regret that the thin and light book is not strong and unique. With the blessing of Lightning 4, you can connect a high-speed hard disk outside, connect a graphics card extension dock and display at home, taking into account both performance and portability.

The charger included in the package is 100W PD. The size is much smaller than last year, so it should be using gallium nitride technology. At the same time, you can also charge Xiaomi's mobile phone quickly, and you can take one less charger when you go out.

Hardware introduction next let's introduce the hardware specifications of Core i5-12450H. Core i5-12450H is i5 as i5-12500H, but the number of cores is not the same. It has 4 performance cores and 4 energy efficiency cores, which is less than i5-12500H. Among them, the performance core supports hyperthreading technology, with a total of 8 cores and 12 threads, so i5-12450H is actually more single-core performance. The third level cache is 12MB. It is worth mentioning that the nuclear display aspect has been changed to the Xe nuclear display of 48EU, which is a bit ruthless.

Next, let's introduce AMD's R7-6800H. The hardware specification of R7-6800H is 6nm process, which is still 8 cores and 16 threads, the main frequency of 3.2GHz, the Rui frequency of 4.7GHz, the three-level cache of 16MB, and the power consumption of TDP is also 45w. The biggest highlight of R7-6800H is that its core display has been upgraded to 680m of AMD's latest RDNA2 architecture, and the more advanced TSMC 6nm process can also bring better energy consumption ratio.

In terms of parameters, the single-core performance and peripheral interface of i5-12450H will be better, while the nuclear display and energy-efficiency ratio of R7-6800H will be better. However, since the core size of the i5-12450H is not exactly the same as that of the i5-12500H we tested before, the battery life performance should be greatly improved, and then we will conduct a performance test.

Theoretical running points next we carry on the theoretical test, because the two molds are basically the same, so the performance release is basically the same. The power consumption of i5-12450H is about 51W, the temperature is 93 ℃, the power consumption of R7-6800H is about 54W, and the temperature is about 88 ℃. It is not a problem for this mold to press the H45 processor.

After the theoretical run, CTOnews.com tested CPU-Z and R20, R23 and 3DMark TimeSpy. It can be seen that the single-core performance of i5-12450H is stronger, while the polynucleus and kernel of R7-6800H is superior.

Taking R7-6800H as the 100% benchmark for tabulation, we can see that i5-12450H is about 10% of the single core. The multicore performance lags behind by about 17%. The difference in orientation of the two CPU determines that they are suitable for different working conditions.

Productivity comparison so what kind of different work scenarios are these two processors suitable for? CTOnews.com has tested some productivity running software for you. First of all, the software CrossMark, which represents comprehensive office performance, scored 1662 points on the RedmiBook Pro 14 2022 Core version of i5-12450H.

And RedmiBook Pro 14 2022 sharp dragon version here will be slightly inferior, with a score of about 1537 points, it seems that this software pays more attention to CPU single-core performance.

PS image modification is the demand of many business users. In PugetBench For Ps, i5-12450H scored 810 points, while R7-6800H scored 784 points. It seems that PS software is more likely to eat single-core performance. CPU's i5-12450H with excellent single-core performance will have a slight advantage.

In the video clip test PugetBench For Pr, i5-12450H still had a big lead, with a score of 422 points, compared with 294 points for R7-6800H. The reason for this is that although the performance of AMD kernel display is powerful, the ability of video codec has always been a deficiency. The Intel Xe kernel is more powerful in the video codec.

Battery life is also a concern for many light and thin book users, and you may be worried about the battery life of the 12th generation of cool and thin books, but we actually tested it with PCMark10 modern office and found that the gap is not that big. The measured version of Core lasted 9 hours and 17 minutes, with a score of 5791 points. The Rui long version has a battery life of 10 hours and 2 minutes, with a score of 5181 points. It is true that the Rui Rui version has a higher score and the Rui long version has a longer battery life, but the gap between the two is not obvious.

From our above tests, we can see that in projects that test single-core performance and core codec capabilities, RedmiBook Pro 14 2022 Core i5-12450H will be slightly better, while Ruilong version is more suitable for light jobs thanks to the excellent low-load energy consumption ratio of 6800H.

Don't forget that the RedmiBook Pro 14 2022 also comes with a unique 2.5K 120Hz screen at this price. So can their nuclear display play mainstream online games? In order to run as many frames as possible, we manually lowered the image quality to 1200p in the following tests and tested several mainstream e-sports games.

The first is "CS:GO". Under its own BenchMark, both computers can run smoothly.

I5-12450H average 71 frames:

R7-6800H average 176 frames:

In another e-sports game, "Watch Vanguard: return", the optimization is much better. Both of them can meet more than 120 high frames to play freely. Cherish it, play one day less.

I5-12450H training ground average 131 frames:

R7-6800H average 207 frames:

In the "League of Legends" who pays more attention to the performance of CPU, the gap between the two is not so big.

I5-12450H average 150 frames:

R7-6800H average 167 frames:

Generally speaking, although the physical performance of the two graphics cards is indeed poor, but in the actual e-sports game experience, are smooth play, as long as not forced to play 3A, the daily online game experience will not be too different. As for the experience of the 3A masterpiece, it should be handed over to the Lightning 4 interface external graphics dock.

Conclusion: who says that cost-effective and high-end sense cannot coexist? if more than 4, 000 prices recommend which lightweight book, RedmiBook Pro 14 2022 will definitely be on the author's recommended list. Its all-metal CNC body, the rare 2.5K 120Hz high score and high brush screen, and excellent performance release are all too good to come from this price.

In terms of version selection, the single core performance of the RedmiBook Pro 14 2022 Core version is more excellent, and there is no obvious deficiency in energy efficiency. The most important thing is that its price is about 800yuan lower than the Rui long version, making the price come to more than 4000, and the performance-to-price ratio is more prominent. Unless there is really a niche demand such as "occasionally play 3A with nuclear display", the author thinks that RedmiBook Pro 14 2022 Core i5 is a more cost-effective choice.
