Re interpret what is "performance" Lenovo Xiaoxin Pro 14 2021 evaluation

With its excellent performance tuning, Lenovo's Xiaoxin series has become Flimsy edition I am afraid that the "performance benchmark" in the light and thin market will not be able to distinguish the right one. In October, after the official release of Intel's 11th generation Core, the Xiaoxin series ushered in a wave of updates again. The Pro family has added a 14 inch version with a larger screen, which continues the traditional advantages of the Xiaoxin series and brings us many highlights. At the first time, we got this Lenovo small new Pro14 2021. Let's have a look.

The keyboard on the C side has a key stroke of 1.3mm, and the rebound is simple. The typing feel is still the same as before. This is also a major feature of the Xiaoxin series from beginning to end, as is the case with the new Lenovo Xiaoxin Pro14 2021. The touchpad covers the glass panel, which is officially said to be Lenovo's whole line notebook It is the largest one in the world. Its surface is covered with glass, and the operation experience has been improved to a certain extent.

Both keyboard and screen support intelligent dimming, which can automatically adjust the screen brightness and keyboard backlight brightness according to the environment. The leftmost Ctrl key is also printed with a "sound" icon, which is Lenovo Voice. Wake up with the shortcut key Fn+left Ctrl, a bit like a smartphone Voice Assistant After waking up, directly say what to do, such as "open Steam ”, it will open automatically Steam The program, or "search Lenovo with Baidu", will open automatically browser , search the keyword "Lenovo" through Baidu, and display the search results.

In terms of interface, there are two lightning 4 interfaces on the left side of the fuselage, and the power switch USB 3.2, 3.5mm headset microphone two in one interface. Although the Lenovo Xiaoxin Pro14 2021 is a thin and light notebook at the mainstream price, the two Type-C interfaces are the lightning 4 of the highest specification, without shrinking, and can output at full speed at the same time, supporting dual 4K 60Hz display expansion.

16: The screen ratio of 10 can obtain a larger visual area in the office scene. In browsing the web, consulting materials, and writing documents, the 16:10 screen can provide more information in the same screen, reducing the number of times to scroll the screen. Over time, the work efficiency brought by the 16:10 ratio can not be underestimated. At the same time, the screen of Lenovo Xiaoxin Pro14 2021 has passed the triple eye protection certification: DC dimming and non stroboscopic+hardware level anti blue light Rhine T ü V certification+Eyesafe Rhine T ü V certification. For those who spend a long time staring at the computer screen to work, this configuration point can relatively reduce eye fatigue and eye damage.

The machine also has a built-in "Lenovo Xuanyuan AI" smart chip, which, together with the front camera and sensor, can achieve more accurate face recognition, and the boot and unlock speed will be faster.

The measured screen covers 98% sRGB, the maximum brightness is 320 nits, the average value of color accuracy △ E=1.04, and the color reproduction is high, so it can be competent for some design work

03 Performance release, no disappointment

Performance must be the highlight of the Xiaoxin Pro series. Let's talk less about it and look at it directly.

During the performance test, the beast mode is always enabled. The BIOS version of this test is FJCN21WW, EC The version is FJEC21WW.

The test model I took was the standard version, which was equipped with the 11th generation Core i5-1135G7 processor, 10nm SuperFin technology, four cores and eight threads, and the maximum Remax frequency was 4.2GHz. Intel officially gave the TDP up to 28W.

CPU basic information

In the CINEBENCH R20, the multi-core score is 2379, and the single core score is 514. Intel's 11th generation Core's single core capability has been greatly enhanced. Under the unique performance tuning of Lenovo Xiaoxin, the multi-core performance is equivalent to the i7-9750H, while the single core performance is equivalent to the desktop i7-10700K. This is an exaggerated improvement. You should know that this is just a piece of low-voltage U.

CINEBENCH R20

In 30 consecutive rounds of CINEBENCH R15 multi-core performance tests, the trend of Lenovo's small new Pro14 2021 is almost a straight line. It is amazing that a thin and light notebook can have such a high energy output heat dissipation capacity.

By comparison, it can be regarded as the mobile version of the GTX 1050 (DX12 has better performance than the mobile version of the 1050, DX11 Performance is weaker than mobile version 1050).

The memory specification is also quite strong. The dual channel 16GB LPDDR4x 4266MHz, the measured read, write, and copy speeds are 62129MB/s, 66038MB/s, 60095MB/s, and 59.1ns in delay. The speed is fast, the capacity is large, and the delay is low.

Cache&Memory Benchmark

With the powerful single core processor, super large MX450 and high frequency memory, how does Lenovo's new Pro14 2021 perform in games?

In the game test, the resolution is always set to 1920 * 1200 (adapted to the 16:10 scale screen).

On《 Dota2 》In, the picture quality is the highest by default, as shown in the figure below, when watching a game just started on the home page, the average frame number of the whole game is 95 frames from the automatic perspective, and it does not fall below 60 frames during large-scale group war.

On《 CS In: GO, the picture quality is adjusted to low, anti aliasing 2XMSAA. Because there is no built-in Benchmark in CS: GO, and because the number of players and maps are different, the frame number can not be well evaluated, so we choose FPS BENCHMARK map in the creative workshop for the frame number test. This is the current popular CS: GO frame number test, with an average of 199 frames.

The hardware combination of the 11th generation Core+MX450 has brought the performance of the thin and light notebook into a new field. With the outstanding performance tuning of Lenovo Xiaoxin, it has been able to run all kinds of e-sports online games perfectly and smoothly without compromising the picture quality. Even the hardware hungry game "PUBG" can complete the whole game in most cases of more than 60 frames.

Finally, test the hard disk, PCIe NVMe SSD、 The capacity is 512GB, the maximum read speed is 3533MB/s, and the maximum write speed is 2987MB/s. The current flagship speed performance.

04 Heat dissipation test

First, perform the single bake test of the CPU, 30 minutes after the Stress FPU, The CPU power consumption is stable at 38W, the temperature is 95 degrees, and the frequency is not very stable. The four cores fluctuate between 3.2GHz and 3.8GHz. Occasionally, one or two cores fall below 3.0GHz.

Single bake test

Next is the double bake test. We use the Stress FPU+FurMark 1920 * 1080 to test. This test has a heavy load and is not usually used in thin and light books. 30 minutes later, Lenovo Xiaoxin Pro14 2021 CPU temperature 87 degrees, power consumption 20W, frequency fluctuation between 1.8GHz and 3.2GHz; The GPU has a temperature of 79 degrees, a frequency of 1545MHz, a maximum power consumption of 33.5W, and a stable power consumption between 25W and 33W.

Double baking test

This is a light and thin product with the thinnest part of less than 15mm. Single baking is 38W stable, and double baking can achieve the performance release of 20+28.5W, which is quite excellent, as given by the official Xiaoxin. Although the frequency of the processor and the power consumption of the graphics card are not stable, they remain at a high level most of the time. After all, they are new hardware, and subsequent Bios will certainly fix these problems.

From this point of view, the Lenovo small new Pro14 2021 is equipped with a 95W power supply as standard. There is still a lot of surplus. It must be prepared for faster charging.

05 Long life+95W fast charge

Lenovo Xiaoxin Pro14 2021 is equipped with 61Wh large capacity battery, which supports fast charging technology. The standard power supply is 95W high-power Type-C PD fast charging power supply.

PCMARK 10 modern office endurance test: 10 hours and 18 minutes

In the PCMARK 10 modern office mode, the endurance of the Lenovo Xiaoxin Pro14 2021 was 10 hours and 18 minutes. Then I recorded its charging speed, which took just one and a half hours to charge from 7% to 97%. The endurance of more than 10 hours can basically meet the requirement of working without plugging in all day, and the fast charging technology can quickly restore blood and eliminate endurance anxiety.

06 Summary

In terms of games, Lenovo Xiaoxin's Pro14 2021 enables the slim and light notebook to "eat chicken" smoothly, and other e-sports online games are even more accessible. With the super large cup hardware configuration and extremely strong performance release, Lenovo Xiaoxin has defined the performance of the slim and light notebook to a new height.

In office work, with a 16:10 screen, three eye protection certifications, and a 2.2K high color gamut, Lenovo Shin Shin has basically achieved all that it can do. Under the premise of comfortable office work, Lenovo Shin Shin cares more about eyes. It has also conscientiously assembled a large capacity battery and a power supply that far exceeds the performance requirements, and strives to achieve outstanding performance in all aspects.

In terms of product design, the new mold is undoubtedly a bright spot. Compared with the previous Pro series, it has a larger touchpad and the same comfortable keyboard operation Voice Assistant With the "Xuanyuan AI" chip, Lenovo is no longer simply working on performance, but on this basis, trying to increase the user's product experience.

Considering the price of 5799 yuan for the first launch, I can't think of anything else except "sincerity".
