RedmiBook Pro 14 2022 Review: Performance Increased By 45%

Intel’s 12th-generation Core is the generation that has changed the most in recent years: the new Intel 7 process technology, the new Golden Cove CPU architecture, and the new heterogeneous hybrid architecture have achieved a leap in both single-core performance and multi-core performance and achieved energy efficiency. to a whole new level.

Especially with the innovative hybrid architecture, Intel has broken through the bottleneck between multi-core and multi-threaded load and power consumption of processors. Through Intel’s hardware thread scheduler and underlying AI technology, it can intelligently allocate tasks and allocate power consumption to maximize energy efficiency.

This kind of performance and energy efficiency can also have both fish and bear’s paws, which is a great benefit for notebooks, especially thin and light notebooks.

In the past, the H-series standard-pressure processors for game notebooks can also be easily transferred to thin and light notebooks, which frees them from the standard “4 cores and 8 threads” standard for many years.

The RedmiBook Pro 14 2022 that we received this time by Kuai Technology is equipped with the i5-12450H from the 12th-generation Core H45 standard pressure series.

The Redmi Book series can be said to be one of the most popular thin and light notebooks on the market. While inheriting Redmi’s consistent ultra-high cost-effective features, both design and configuration are quite sincere.

As a thin and light notebook, the weight of the RedmiBook Pro 14 2022 is very accurate. It uses a metal body and is controlled at 1.45kg. Whether it is working in the company, watching dramas at home, or traveling for work, it can be used anywhere, and the usage scenarios are very flexible.

The i5-12450H is the entry-level model in the 12th-generation Core H45 series, but it still provides 4 performance cores, 4 energy efficiency cores, a total of 12 threads, and a 12MB L3 cache. The single-core turbo frequency can reach up to 4.4GHz. The core graphics card integrated with 48 execution units has a basic power consumption of 45W and a maximum turbo frequency of 95W.

The 14-inch screen has a high resolution of 2.5K, a high refresh rate of 120Hz, and a high color gamut of 100% sRGB. PCIe 4.0 SSD and LPDDR5 memory do not have any bottlenecks. Thunderbolt 4, USB-C, USB-A, HDMI, and other rich interfaces can also meet the needs of various scenarios.

Next, let’s take a look at the performance of this Redmi Book Pro 14 2022.

Design

The surface of the RedmiBook Pro 14 2022 is relatively simple and stylish. The A/C/D is made of all-metal material. The A/C surface is a CNC finishing process, and the surface is made of 170 ceramic sandblasting, which can bring a delicate feel.

The overall size is only 315.6×220.4×15.9mm, which is not too big, plus the weight of 1.45kg (the standalone version is 1.5kg), it can be used with one hand.

The B side is a 14-inch IPS screen with a resolution of 2560×1600, 120Hz refresh rate, 100% sRGB high color gamut, 300nit high brightness, 1000:1 static contrast ratio, daily browsing, and web page drama will be more delicate, plus Light Sensor The intelligent photosensitive function can adjust the screen brightness according to the ambient light, which is more eye-friendly when using.

The display ratio is 16:10, which can display more content and improve office efficiency. The C-face keyboard supports four-speed backlight adjustment, and the feedback is obvious when typing with a 1.3mm keystroke. The large-area touchpad provides a more precise operating experience.

The power button in the upper right corner of the C side supports fingerprint recognition, and there is a Xiaoai classmate button below it, which can be used to call out Xiaoai classmates to interact with one click.

On the left side of the laptop are Thunderbolt 4, HDMI 2.0, and 3.5mm audio output and input two-in-one jacks. On the right are the USB-C 3.2 Gen1 and USB-A 3.2 Gen1 interfaces. There is a large area of ​​mesh metal heat dissipation grid on the D side, as well as a lengthened foot pad, which avoids the problem of poor heat dissipation when it is flat on the desktop.

With the 100W charger and dual USB-C charging cables included in the package, the charger supports PD 3.0 fast charging protocol, and can also charge mobile phones when going out every day.

Performance

As before, although the i5-12450H is an entry-level model of the H45 series, it still gives 4 P cores + 4 and E cores to form 8 cores and 12 threads. Among them, the P-core turbo frequency can reach 4.4GHz, the E-core turbo frequency can also reach 3.3GHz, and the third-level cache still has 12MB.

Hardware dog

In the wPrime test, it took 33.816 seconds for the 32M single-threaded benchmark and 138.155 seconds for the 1024M multi-threaded benchmark.

International chess

In the chess test, the relative performance multiple reached 50.47, 24,223 thousand moves per second. In the CrossMark benchmark, productivity, creativity, and responsiveness were fairly well-balanced, with an overall score of 1,698.

Compared with the i7-11370H of the previous generation for high-end thin and light notebooks, the i5-12450H of the 12th-generation Core H series entry model has achieved a leap forward, and the single-core performance is 6.4% higher.

You must know that the maximum acceleration frequency of the i7-11370H can reach 4.8GHz, but the i5-12450H is only 4.4GHz, which naturally benefits from the new generation of architecture design.

At the same time, the multi-core score has skyrocketed by 44.9%. This is the difference between 8 cores and 12 threads and 4 cores and 8 threads. The added 4 energy-efficient cores can greatly expand multi-task load applications. “.

Nuclear Display Performance

The core display specification of the Intel Core i5-12450H is 48 EU units, the maximum frequency is 1.2GHz, and it can support up to 4K resolution output support.

If players want to play games such as LOL and Overwatch that do not eat real-time rendering, it is no problem.

Benchmarks

In the Fire Strike project of 3Dark, the Intel UHD core display on the Core i5-12450H gave a score of 2978 points.

Game test

1. World of Tanks

World of Tanks ran 13557 points, with a converted frame rate of 46 FPS.

2. Overwatch

We turned on medium quality in Overwatch, up to 110 FPS, and maintained 70-90 FPS even in multiplayer battles.

5. Screen and others

Screen

The RedmiBook Pro 14 2022 model uses a 14-inch IPS screen with a resolution of 2560×1660 and a 120Hz refresh rate. It has passed the TÜV Rheinland low blue light certification and supports software anti-blue light.

Let’s use the calibrator to see how the screen performs on this screen.

The color gamut of this screen supports 95% sRGB, 71% Adobe RGB, and 72% P3. The maximum brightness of this screen is 312 nits, and the maximum brightness can reach 1040:1, which is the level that an IPS screen should have.

In terms of color accuracy, the highest Delta E value of this screen is 7.43, the lowest is 0.11, and the average Delta E value is only 0.69. Among them, the value of the blue part is high, which should be due to the blue light filter processing of the screen, which leads to the deviation of the color calibration instrument.

For ordinary users, the Delta E is invisible to the human eye between 3 and 6, and the Delta E is lower than 2, and it can be used as a professional screen.

Memory

The Redmi Book Pro 14 2022 uses 16GB LPDDR5 5200MHz dual-channel onboard memory. We performed the memory cache test on AIDA64, and the measured read, write, and copy bandwidths were 66190MB/s, 63244MB/s, and 65195MB/s, respectively. The delay is 114ns.

Hard disk

In the CrystalDiskMark test software, the measured sequential read speed is 3463MB/s, the write speed is 2783GB/s, and the 4K random speed is 62MB/s read and 177MB/s write.

It is entry-level among PCIe 4.0 SSDs, but even so, the performance of this SSD is slightly better than that of high-end PCIe 3.0.

Battery

We first turn on the “best performance” in the power supply, and the FN+K shortcut key changes the mode to “extreme speed” mode. Using AIDA64 for the FPU roaster, when the roaster starts, the instantaneous power consumption of Core i5-12450H reaches 63.8W, and then the power consumption stabilizes at around 42W.

After 10 minutes, the temperature is about 94~96 degrees Celsius, the maximum frequency of the P core is 3.6GHz, and the maximum frequency of the E core is 2.8GHz.

In theory, the performance release of i5-12450H can reach 450W stably, but it should be due to summer, and it almost failed to achieve it.

Because the RedmiBook Pro 14 2022 is positioned as a thin and light notebook, it is necessary to take into account the high temperature in summer, which also has a certain impact on heat dissipation. In addition, the thin and light notebook does not require extreme release, so the power consumption strategy is controlled conservatively, but even so, This performance is sufficient for most users.

Battery Life Test

The Redmi Book Pro 14 2022 has a built-in 56Wh battery, and we use PCMark’s modern office to test the battery life. During the test, we changed the screen brightness to 50% and the power mode to the best energy efficiency. The result is about 6 and a half hours of battery life, which can be used intermittently for most of the day.

Verdict

Intel released the 12th-generation Core mobile version at the beginning of the year, but in the market, notebooks equipped with H-series high-performance models are one after another, and U-series low-power models are invisible.

We didn’t understand what was going on for a while, but after experiencing the RedmiBook Pro 14 2022 model, the truth is very simple: the positioning of this generation of product lines has changed, and the H series, with its great progress in energy efficiency, has been able to “cross-border” world” into thin and light notebooks.

In the past, when it comes to thin and light notebooks, the traditional impression is that the performance is sufficient, but the emergence of the 12th generation Core, especially the changes in the H series, has changed all of this. The changes brought by the heterogeneous hybrid architecture have made thin and light notebooks also Can have high performance, especially multi-core performance.

Although the i5-12450H is only the entry-level model of the 12th-generation Core H series, thanks to the leaps in a hybrid architecture, CPU architecture, process technology, and other aspects, even compared with the previous generation i7-11370H, not only the single-core has increased by more than 6%, The multi-core performance has exceeded a full 45%, and the four energy-efficient E-cores are indispensable.

This means that in daily office, image editing, PPT processing, video conferencing, simple games, and other scenarios, the Core i5-12450H can ensure that performance will not become a short board, and office efficiency will skyrocket.

At the same time, it can also “bend and stretch”, with higher performance, and it can also provide 6-7 hours of battery life, even if you go out to work temporarily, you don’t have to worry about power.

In addition, this product is also equipped with a 2.5K 120Hz high-resolution high-brush screen and adopts CNC integrated carving process, the screen and texture are rare at the same price. The Redmi Book Pro 14 is priced at 4499 yuan during the 2022 618 period, which is very cost-effective, which once again reflects the true nature of Redmi’s “cost-effective butcher”.
