Light as a feather steady old iron | Ryzen and Ta are real great!

The introduction of Ryzen Intel unprecedented pressure on both desktop processor and mobile processor, Intel has a huge threat to performance, and as a qualified notebook manufacturer, also known as the ability to recognize the beads Must have, in Ryerson mobile processor (Ryzen mobile processor) came out, the major manufacturers soon announced that they will launch the corresponding notebook products, and Lenovo also introduced its own corresponding products, today we have to say IdeaPad 720S is such a product.

Features: Rui Long mobile processor Fingerprint Identification | Micro Borders
advantage: High-precision touchpad | 91% sRGB color gamut screen | light and portable
Evaluation: This lightweight and efficient use of life and convenience have a great help, Rui Long 5 2500U is with a color performance, very good

First impression

The first time I saw this notebook, it's compact and slim body attracted me, often go out, or want a notebook so light.

B side Lenovo logo printed on the bottom left of the screen, looks very chic.

For this notebook, its biggest bright spot is undoubtedly the Rui Long mobile processor, AMD's Logo quietly lying on the C side of the corner, low profile but can not hide their own light.

In addition, the screen reversal of this notebook uses a hinge design, the maximum opening and closing angle of nearly 180 degrees, the adaptability of the environment is still very tricky.

As for the interface, it is equipped with two USB Type-C ports and a USB 3.0 port on the left, while on the right, the notebook is equipped with a USB 3.0 port and a headphone / microphone combo port.

Comment

First impression of this notebook gave me the impression is not bad, not much about the interface, but also enough to cope with most situations, and the most eye-catching fact is AMD's Rui Long mobile processor, in the past year, AMD really hit it by a beautiful turnaround, and in the notebook platform, its performance is worth the wait.

Processor usage experience

The value of a notebook geometry, in addition to its appearance, the use of experience is clearly the most important, but for this notebook equipped with Rui Long mobile processor, the actual performance of the processor is the focus of attention Before we start the formal test, let's take a look at the experience. (For comparison, we also asked for i5-8250U for reference).

4K video playback

Play 4K video for the processor, of course, there is a certain requirement, compared with the i5-8250U, but also be able to clearly understand Ryzen5 2500U processor performance.

In the above two pictures can be seen, when playing 4K video, both processors can easily cope with full-screen view of the CPU occupancy rate of only 3%, and if the 4K video playback, frequent Switching windows, CPU utilization is only reached 30%, 31% level only.

unzip

The decompression in contrast is a very dependent on the performance of the processor operation, I believe you downloaded the game players know that after each download finished the game after a long period of decompression in order to successfully enter the game, then, with i5-8250U compared to which processor more advantages?

Left: i5-8250U Right: Ryzen5 2500U

We learned the real answer by unziping the game "Dishonored 2", which is about 23GB. By comparing the decompression time, we can see that on the left i5-8250U time of 6 minutes and 39 seconds, while the right of the Ryzen5 2500U is only 6 minutes 16 seconds, ahead of a full 23 seconds, very good.

Processor run sub-test

Indeed, this time the Ryzen5 2500U processor gives the IdeaPad 720S brings a big advantage, for me acute, the laptop's data processing efficiency than anything else, in order to further confirm the strength of this processor, running points Of course, testing is also essential.

CINEBENCH R15

In the CINEBENCH R15 test, Ryzen5 2500U easily get 533cb integrated run points and 130cb single-core run points, in order to ensure the reliability of the data, this test we ran a total of 5 times, each time the scores are different 7 points, the performance is very stable.

In CPU-Z processor test, Ryzen5 2500U got a single-core score of 1955 points and 6678 points of multi-core scores, almost equal to i7-3960X, and this, and i7-8550U scores are almost the same.

Left: Ryzen5 2500U Right: i7-8550U

On the hardware data, the notebook is equipped with Ryzen5 2500U is a 14-nanometer process 4-core 8-thread processor, the basic frequency of 2.0GHz, up to 3.6GHz.

Notebook performance test

Of course, not only the performance of the notebook to see its processor, hard disk read speed, the screen parameters are also very important, and integrated several factors, its ultimate performance is the user's concern.

SSD literacy

Through CrystalDiskMark this software, we first test the IdeaPad 720S equipped with a solid state drive, 4k sequence read and write capabilities has always been the most intuitive test of the strength of a solid state drive data, and this laptop is equipped with a solid state drive Get 43.06MB / s 4k reading results and 120.4MB / s 4k writing scores, is quite good performance.

In the AIDA 64 memory test, the notebook's 8GB memory also has a good performance.

As for the screen, this notebook is equipped with a LG screen, model LP133WF4-SPB1, it is an IPS screen, the maximum resolution of 1920 * 1080, the pixel frequency of 138.70MHz.

In addition to the properties of the micro-border, this notebook screen also has excellent color gamut level.

With the Spyder5Elite 5.1 color gamut test software, we finally measured 91% of the sRGB color gamut and 68% of the NTSC gamut on this notebook screen - a delectable color for friends It is particularly important.

Overall performance, we finally chose to use PCMark 8 for comprehensive performance evaluation, the final notebook in the home (HOME) mode test made 2959 points, the web browsing speed also has a good performance.

Life, weight, size notebook the first impression of the key

But for the most part, it's clear that for most people, it takes time for a PC to show its importance, and things like performance tests for processors and other hardware may not be taken into account - they are more concerned The size, weight, and endurance performance of this notebook are closely linked to the experience of the actual use.

Size and weight

This notebook is about 305mm * 208mm, for people who often go out with a notebook, the notebook size directly determines whether it can be put into the bag - and this size is very good.

In terms of thickness, after the vernier caliper measurement, I found that the thickness of this notebook was only 14.12mm.

Size is not big, the weight naturally will not go high, the weight of this notebook is only 1.11kg, just a book more than two hundred pages may be heavier than it, of course, will not be loaded into the bag burden .

How the life performance

The laptop battery capacity of 47Wh, and in the PCMark 8 battery life test, this notebook has made 3 hours and 17 minutes of performance, be considered a more mainstream performance, daily office life is expected to be up to 5-6 hours .

Use experience

The use of experience, a thin and light of this most intuitive experience than its touch pad and keyboard, and this laptop's touch pad recognition accuracy is good, for multi-gesture operation is very good experience.

The keyboard feel the damping is too large, rebound is also more favorable, when typing experience is still very good, very texture (of course, this kind of thing or to consider everyone's favorite).

In addition, this notebook is also equipped with a fingerprint protection function to protect user privacy and data. Replacing the power-on password with fingerprint login apparently greatly reduces the risk of password loss - and this login is also more convenient.

to sum up

Obviously, equipped with the Rui Long 5 2500U processor IdeaPad 720S processor performance really has a good advantage, and strong SSD read and write capabilities also brought it worthy of recognition experience, 305mm * 208mm body The size also makes it very easy to use, it is travelers need laptop (this is not exactly the meaning of notebooks?), And micro-border screen and 91% sRGB color gamut level does bring a good visual experience As for the experience, touchpad and keyboard performance really surprised me a lot - for me anxious, nothing annoying annoying even more disappointing, but the Lenovo IdeaPad 720S in this regard Well done, in this price notebook, can have such a experience can really say that value for money.

All in all, this laptop will not disappoint you if you have expectations for light-weight and productive life - Is not it just a matter of time since the art of a fresh life begins?
