However, with the rapid development of science and technology today, will notebook computers be as unbearable as we think? The answer is from the high-performance ultra-thin notebook we are going to evaluate today-Samsung Obsidian 900X5T.
At the end of 20 16, Samsung updated its Yao Xing series. The biggest highlight of this series of models is that the notebook with 13.3-inch screen is still 799g (only half the weight of ordinary 13.3-inch thin notebook), and the ingenious design combines ultra-thin and large screen. It can be said that few manufacturers can reach the technical level of Samsung at that time.
At the beginning of this year, Samsung Obsidian Series (English name "Notebook 9") incorporated Intel's eighth-generation Core i5/i7 processor and NVIDIA GeForce MX 150 2G discrete graphics card, truly integrating ultra-thin, large screen and high performance into this 15 inch Samsung Obsidian 900X5T ultra-thin notebook. At present, the price of this notebook is around ten thousand yuan. Click to view details.
From the design point of view, there is no special muscle line on the A side of the notebook, and the overall appearance is simple and generous. The four corners are all popular rounded corners, which can not only improve the grip, but also help to evenly disperse the external force from the mechanical point of view, so that the product can obtain better stability.
On the right side of panel A, a line of Samsung logo is added, which is very personal and recognizable.
15 inch screen, all-metal body is also very light;
According to the actual measurement, the weight of Samsung Yao Xing 900X5T is 1.24kg, which is even more beautiful than the official data of 1.29kg (1.2kg is about the weight of two bottles of mineral water). If I remember correctly, Samsung is the only manufacturer that can make notebooks as big as 15 inch 1.24kg at present.
If you bring your own 65W power supply (notebook 100 minutes can be fully charged), the travel weight is1.456kg. According to the evaluation experience, this weight is equivalent to the single weight of an ordinary 13.3-inch notebook. But Samsung Yao Xing 900X5T is a notebook with 15 inch screen.
In terms of workmanship, Samsung Yao Xing 900X5T notebook adopts magnesium-aluminum alloy Metal 12 body treated by micro-arc oxidation process. Although the notebook feels light in my hand, it can bring me a strong sense of security, because magnesium-aluminum alloy has the characteristics of high toughness, electrical insulation, corrosion resistance and easy heat dissipation. Generally speaking, this material is one of the preferred shell materials for ultra-thin notebooks at present.
The 98%sRGB screen is excellent:
Samsung Yao Xing 900X5T is a 15 inch notebook computer product, but its body size is only about 14 inch ordinary notebook. Why? It is precisely because the Samsung Yao Xing 900X5T adopts a 6. 1mm ultra-narrow bezel screen.
Screen quality has always been a very important point of Samsung products. As we all know, the screen of Samsung mobile phone usually brings us a sense of surprise, which is also true in notebook products.
According to the official statement, Samsung Yao Xing 900X5T is equipped with 15 inch 1920* 1080 FHD full HD Realview display with a color gamut of ≥95% and δ E.
For this screen, we tested it with Starscream 5, and the results show that the color gamut of this screen has reached 98% sRGB, which is very excellent and can meet the basic needs of designers and photographers to edit pictures.
Like many high-end business books like X 1 Carbon on the market, Samsung Yao Xing 900X5T has a screen that can be opened and closed at 180, and the contents displayed on the screen can be turned by pressing the key combination Fn+F 1 1, which is convenient for many people to watch in business meetings and other scenes.
In addition, the screen hinge with a larger opening and closing angle can also make us more comfortable when using the notebook on our legs.
On the C side of the notebook, the small keyboard is cancelled, and a keyboard with a larger keycap is replaced, which has a better feel, and the silver keycap and the C side made of aluminum-magnesium alloy are also in harmony. In terms of feel, Samsung's notebook keyboard is more flexible, and long keystrokes can provide a good input experience.
The keyboard of 900X5T alien obsidian can turn on the white backlight, and the brightness can be automatically adjusted according to the environment, which is somewhat similar to the automatic brightness level of the mobile phone screen. It will automatically turn off during the day, save electricity, and automatically turn on at night, which is very user-friendly.
▲ The power switch key is located in the upper right corner of C-plane.
As shown in the sticker, Samsung Yao Xing 900X5T comes with genuine Windows system and office 20 16 family and student edition suite, so you don't have to be afraid to buy a computer, and you can use it directly for office work without paying extra for software, which is quite convenient.
There is a key with fingerprint recognition on the right side of the direction key in the lower right corner of C plane, which is a capacitive fingerprint recognition module. As a high-end business notebook product, security is not only reflected in the strength of the fuselage, but also in the protection of user data.
At present, fingerprint identification has become the standard function of high-end business notebooks. Compared with passwords, fingerprint identification is more secure and faster to open. We can use the fingerprint identification and unlocking function of Windows 10 operating system to achieve millisecond user login operation.
For business people, video conferencing is inevitable. A 720P camera is placed above the screen of Yao Xing 900X5T, which can easily meet the needs of users for video communication. There is also a far-field microphone next to the camera, which can clearly capture the sound of us sitting in front of the computer.
Complete interfaces and various types:
In terms of interfaces, although the fuselage is light and thin, the number and types of interfaces are very rich. The right side of the fuselage is equipped with two USB-Type A interfaces, a Micro SD card slot and an HDMI interface.
The left side of the fuselage is equipped with a 3.5mm earphone interface, a dedicated charging port and a Type-C interface. Among them, the Type-C interface supports 10W- 100W wide-power charging (supporting the Type-C chargers of most mobile phones and tablets on the market), and this notebook can also be used as a mobile power supply to charge other devices.
Basic performance test:
In terms of machine configuration, the Samsung Yao Xing 900X5T in my hand uses eight generations of Core i7 8550U quad-core eight-thread processor, 8GB DDR4 2400 memory, NVIDIA GeForce MX1502GB GDDR 5 memory discrete graphics card, and 256G Samsung NVMe M.2 solid state drive.
Judging from Master Lu's score, this notebook has reached 65,438+073,854 points, which is about 70% higher than the previous generation's lightweight notebook with a running score of only 65,438+0000000.
Moreover, judging from the original game of i5 7300HQ+950M that we have tested before, the running score is only over 15000, but there are not many light notebooks that can reach 170000, so it can be said that the performance of Samsung Yao Xing 900X5T is excellent.
CPU:
The CPU of this notebook is eight generations of Core quad-core and eight-thread CPU, and the power consumption 15W TDP is the same as that of the previous generation, but the number of cores is doubled, and the third-level cache is upgraded to 8MB, and the comprehensive performance is improved by more than 15%.
According to the test results of professional CPU performance test software CBR 15, the multi-core performance of Samsung Yao Xing 900X5T reaches 542cb, and the single core reaches 174cb. The multi-core performance of this i7 8550U equipped on Samsung is improved by about 70% compared with the previous generation i7 7500U's 322cb, and it is improved by about 10% compared with the standard version i5 7300HQ usually installed on the game book.
GPU:
According to the information of GPUZ, its GeForce MX 150 is a full blood version, built with 16nm Pascal architecture, and uses the same GP 108 core as the desktop GT 1030, with similar overall specifications.
We tested it with the new 3dmark, and got 2963 points in the fire attack mode test supporting DX 1 1, which can prove that this graphics card is Hot Blood MX 150, and its performance is about twice that of the previous generation 940MX, which is basically the same as the running score of GTX 950M in the game book.
As for the hard disk, we tested the SSD hard disk of drive C, and the highest reading rate reached 3 190 MB/s and the writing rate reached 1280 MB/s in five 4GB capacity tests each time. It is a PCIE interface solid state hard disk with good quality.
System stability &; Durability test:
We use AIDA64 to copy the CPU, hard disk and graphics card of the computer at full load for 30 minutes to test its heat dissipation performance.
This test is very harsh on the heat dissipation performance of the notebook, because the CPU, graphics card and hard disk of the computer will not be fully loaded when we use it normally.
After 30 minutes of copying, the temperature of CPU and graphics card is stable within 70 (temperature wall limit). Because of the single fan design, the frequency of the graphics card will be slightly reduced due to overheating when running under high load, but the CPU has always maintained a stable state of full blood.
We measure the temperature of the computer through a thermal sensor. It can be seen that most of the heat is concentrated in the middle of the fuselage and discharged to the outside through the cooling fan, while the temperature of the C surface is kept at about 3-40 degrees. This shows that the heat dissipation capacity of this model is still ok.
Thanks to its small size and high technology level, the battery capacity of Samsung 900X5T notebook has been expanded to 75Wh, and it is equipped with a 65W high-power charger.
According to the actual test, 100 minutes can be charged from 0% to 100%. When 1080P HD video play online is performed with screen brightness of 50% and volume of 50%, the battery of Yao Xing 900X5T is still 90% after 1 hour. It is said that the online battery life of Yao 900X5T notebook 1080P video playback is close to 1 1 hour, and it will be longer in other working scenes such as office or web browsing, which can basically meet the needs of a business trip for one day.
Summary:
Generally speaking, the CPU and graphics card of Samsung Obsidian 900X5T notebook are full of blood, and the running score of 1.7 million points is at the top of the current thin notebook, which is close to the specifications of the previous 1.2kg model. In addition, the humanized design of 1.80 screen flipping, fingerprint recognition and keyboard backlight makes mobile office more convenient. In addition, the magnesium alloy fuselage treated by micro-arc oxidation process not only looks high-end, but also has high strength, electrical insulation and corrosion resistance, which also escorts the safety of products. It can be said that Samsung Obsidian 900X5T notebook is the most worth buying at present.
