Thin and light is only the surface performance is king | Xiaoxin | Air preemptive evaluation

At present, the development of the notebook computer market tends to be flattening. As a large piece of cake in the notebook computer market, light and thin is bound to be a must for PC manufacturers. Lenovo's light and thin one of the generals - Xiaoxin, will soon launch 2018 The new product is available. This time, the small new Air 2018 can be said to be very eye-catching in the official introduction, dual SSD slot, full blood version of the MX150 graphics card, support for fast charging and many other selling points have attracted the attention of many users. So this laptop's What is the performance? Let's enter today's test.

PS: This time we got the evaluation model for the small new Air15 and the small new Air14, but unfortunately we have to bring a 15-inch version of the first evaluation, 14-inch version as a guest to do a brief introduction.

Highlights : Dual SSD slot full blood MX150 graphics card memory slot with shield, non-board memory, upgrade space

Upgrade proposal : Due to dual SSD slots, users can expand laptops according to their own situation

Hardware comparison

Hardware reviews

Lenovo's new Air15 in the light and thin in the hardware configuration occupy the position of the upper side, can be considered the mainstream of the light configuration. Overall look small new Air15 is still a good configuration, has a certain cost-effective thin and light notebook.

Appearance

Xiaoxin Air15 uses an all-metal body with side-cut diamonds (C-face, touchpad, fingerprints, and power-on keys). The entire body is full of texture. The body is designed to be simple in style. It is concise, able to use only the design of the new LOGO is impressive. This time the new Air15 is launched gold - streamer gold and silver - Star River silver black - agate black blue - lake blue, four color, for Users have more choices.

The small new Air15 screen adopts a three-frame micro-frame design with a screen ratio of 82.7%. The screen uses a FHD IPS full-HD screen and is covered with Corning's third-generation Gorilla Glass. The resolution is currently the mainstream 1920x1080 specification. Is entertainment or office can meet the needs of users.

As a light and thin, the number and type of the air interface of the new Air15 are absolutely in the front rank of the same type of notebook. On both sides of the airframe, the small new Air15 is placed two USB3.0 (one interface supports shutdown charge), a Type -C, an HDMI, multi-function card reader, headphone jack, one-click recovery.

Small new Air15 has a large screen of 15.6, body weight is only less than 1.927kg. This body weight to carry out will not bring us burden.

Appearance summary

The new series of 2017 new products (20 generations of products) has already won the IF Design Award. Now the 2018 small new full range of design language is more concise, and both sides narrowly evolved into a full series of narrow sides, with over 80% screen share. On the 2017 model, there has been even greater progress. The new Air15 is simple and airy, lightweight and portable, and the interface is relatively complete. The appearance of the new Air15 is still remarkable.

Experience

Laptops have been charging far beyond smartphones because of their large battery capacity. Fast charging technology has become more popular on smartphones, but the use of laptops is still relatively small. The Xiaoxin Air15 is equipped with fast charging technology. More convenient for our daily use. (Data source Lenovo Labs: When the laptop's power is 1%, in the off state, using the standard power adapter after charging for 15 minutes, you can use the MOBILE-MARK at a screen brightness of 50% 2014 test, life time is up to 2 hours. Actual use time may change due to the specific conditions of using the laptop.)

Fingerprint unlocking is no longer a novelty. Basically, all mobile phones and most thin and light laptops will consider adding a fingerprint unlocking module. The new Air15 fingerprint identification time is short, and it can be a more convenient login system.

The size and layout of the small new Air15 keyboard is roughly the same as that of the small new Air14. The keyboard has a keystroke of about 1.3mm, the sense of passage is more obvious, the rebound strength is lighter, and the keycap is smaller. The overall feel is good. And it has second-order. Adjustable backlight, we can adjust according to your own needs.

Lenovo series of computer sound performance are still good, Harman audio + Dolby sound is basically becoming the standard for Lenovo computers. Small new Air15 dual speakers performance is also remarkable.

The cooling module of Xiaoxin Air15 is not shrinking because it is a thin and light, dual fan (fan uses an ultra-thin fan design, using ultra-rigid crystal polymer LCP, making the fan thickness reduced by 30%, performance 20% increase) Cooling. We have a good guarantee of heat dissipation under high light work. The foot pads of our new Air15 have also obtained national patents. The purpose of this wasteful work mat is to prevent Hot air return brings better cooling effect.

Little new Air15 also very intimate to add a shield to the memory slot, and the use of non-board memory, memory can be plugged in at any time left us with an upgrade space. Little new Air15 not only added a shield for the SSD hard disk Cover, and also prepared an SSD slot, to facilitate users to expand hard disk space, which greatly facilitates our use.

I believe that most users will understand the use of the independence of the light and thin on the display - NVIDIA GeForce MX150 according to their power consumption is different from the full blood version, the residual version of the score. The performance of these two will have a larger difference, residual blood Although the performance of the version is a little worse, but the power consumption is lower, the computer's life time is longer. The full version of the version will of course have better performance than the residual version. In order to integrate the advantages of both, Lenovo engineers cleverly The control function for the MX 150 power consumption is added to the underlying BIOS, and the user only needs to use the 'Fn+Q' key combination to adjust the graphics performance.

As can be seen from the above two pictures, we can easily select the mode that we currently need most in terms of endurance and performance through the combination of non-delayed skyjack graphics mode. In the initial batch computer sales system is not equipped Fn+Q function, but do not worry, because we only need to contact Lenovo customer service can download and upgrade to V21 version (7PCN211WW) bios.

PConline evaluation room summary

Lenovo's new Air 2018 models, whether it is design or performance performance can be worth noting. Color match and material selection before changing the traditional design style, simple, low-key body embellishment on the new LOGO This product is on the face value With a lot of improvement, the narrow border is the finishing touch. And the small new Air15 also has a good performance in terms of heat dissipation, and Fn+Q's design to adjust the performance of the graphics card makes people's eyes brighter. Air 15 performance and value fly, is a very good laptop.

CPU test

On the processor side, this notebook is equipped with an eight-generation Core processor i7-8550U. This processor is clocked at 1.80GHz. As a quad-core eight-thread processor, its 14nm manufacturing process and 15W TDP are all Useful assistants in daily use. Plus 8GB DDR4 memory to further enhance the performance of the new Air15.

Compared to the previous generation of processors, Intel's latest generation of Core Duo processors have greatly improved their performance. Through the testing of the theoretical performance of the processor (CINEBENCH R15), we can also see the i7- used by the small new Air15. 8550U processor score of 459cd, low score, performance is not ideal.

In PCmark's Work mode, the final score of the small new Air15 is 4689, which is higher in the same type of laptop.

Hard disk test

According to tests conducted by CrystalDiskMark, the 4K read speed of the new Air15 is 42.42MB/s, and the 4K write speed is 127.9MB/s. Among the many SSDs, the speed is higher.

In actual use, the hard disk read speed is usually reflected by the file decompression, 1GB compression package in the decompression, through the measured time of 11s, this performance is relatively good.

We selected 100 4K images for PS import, and the test time was 1 minute and 30 seconds. The performance was quite satisfactory.

Body size

Test summary

In all aspects of testing, the Xiaoxin Air 15 has relatively good performance, especially the read speed of the hard disk exceeds that of most laptops in the same price range. This kind of performance provides the most basic guarantee for our daily work.
