Many years ago, when I first used the notebook, I had a bad impression on the office book. Its performance is much worse than that of the desktop computer. The 1366×768 weak resolution and 45% NTSC color gamut are really hard to see. The only advantage is that it is convenient to travel.
In the past two years, the situation of laptops has been greatly improved. Especially with Intel’s 10th and 11th generation core processors, the performance and endurance of laptops are no longer a problem. 4-core and 8-thread are the mainstream. Game books can even achieve 8-core and 16 thread, and the frequency is close to or even more than 5GHz, not inferior to desktop computers.
The screen has also changed a lot. 1366×768 screen has basically disappeared, at least 1920×1080 high-definition screen. It is normal to support 100% sRGB color gamut. The visual effect is excellent, the text is clear and sharp, and the image and video color is full and lifelike.
In the 11th generation of core notebook, there is another major change – high refresh rate. At present, office books are basically 60Hz LCD or OLED screens, but Lenovo used 90hz high swipe screen for the first time in its recent notebook yoga14s2021, which is the first time in its lightweight version.
We all have a basic understanding of the concept of screen refresh rate. In short, it is the number of times to refresh the screen in one second. 60Hz is the number of times to refresh the screen in one second. The delay is about 16.7ms. Basically, there is no residual shadow, and the game screen will be relatively smooth.
When the refresh rate is raised to 90hz, that is, it refreshes 90 times a second, and the delay is as low as 11.1ms, which is reduced by about 1 / 3, which is lower than the perceptible delay of human eyes. Theoretically, there is no residual shadow in the picture, and the feeling of switching the picture is continuous.
Gamers have long experienced the benefits of high refresh rate, because many games now have a 144hz refresh rate, which is more than twice as high as the conventional 60Hz. Playing video games such as lol and dota2 is very cool, with smooth pictures and quick response.
Yoga14s2021 is an office book. 90hz is a better comprehensive choice. Because the refresh rate is too high, it will bring some negative effects. For example, the power consumption is significantly increased, and the performance requirements are also higher. After all, from 60Hz to 90hz, it is equivalent to increasing the requirements by 50%. If it reaches 120Hz, it will double the performance.
Fortunately, this notebook uses the 11th generation core processor, and has passed the evo certification of Intel. It has three advantages: fast, long and dazzling. The fast refers to the performance of 11th generation core. It uses the 11th generation core i54 8-threaded processor, and the acceleration frequency can reach 4.2ghz, which is about 20% higher than the previous generation.
Moreover, the yoga14s2021 also supports a more powerful beast mode, which can improve the performance with one click. The CPU performance of the original 15wtdp is upgraded to 38W level, and the performance is improved by 62%. In this way, it will not be difficult to match the 90hz high swipe screen, and it will not get stuck when playing games.
Evo certified notebook has another advantage — dazzle. On the one hand, it means that the design of notebook is fashionable and good-looking. On the other hand, it means that the 11th generation of core irisxe has been demonstrated. This generation has upgraded the new xelpgpu architecture, with a maximum of 96 EU execution units, which is increased by half, and the performance can be improved up to 2 times. It also supports deep learning acceleration instruction dp4a, which can accelerate AI applications.
The game performance of irisxe core display is comparable to that of the entry-level single display, and it can support a number of mainstream games to run smoothly. The popular games such as wizard 3, rainbow 6, watchman and gta5 can all run to about 60fps. The popular electronic games such as turret 2, hero League and CS: go easily exceed 100fps, and some even reach 170fps. There is no pressure for 90hz high swipe screen.
In addition to performance, there are also concerns about battery life brought by high swipe. However, it is not a problem in Evo certified laptops like yoga14s2021. Evo certification standard requires at least 9 hours of battery life and 4 hours of battery life after charging for 30 minutes. This 90hz high swipe laptop provides 17 hours of battery life and 21 hours of video playback.
In addition, it also supports PD fast charging, up to 100W, which can charge 80% power in one hour.
In short, with a large number of 11th generation core laptops coming into the market, the experience of the new generation of light and thin laptops is changing from easy to use to better use. Especially on the laptops with Evo certification, they not only have no pressure on performance and endurance, but also begin to pursue bonus items, such as the first 90hz high brush, to make the smooth experience to a higher level.
This trend is expected to continue. Considering the experience improvement brought by high-speed brush, people will never forget it after using it. In the future, there will be more and more light and thin products supporting 90hz high-speed brush or even 120Hz high-speed brush.
