Thin = performance? Millet notebook Air experience evaluation
Millet notebook, an existence that has been circulating for many years but has not been seen until 2016, Xiaomi Mi officially launched the millet laptop Air in the banner of "thin performance book", a total of two files configuration, respectively 12.5 inches set version and 13.3 Inch alone significant version, Xiaomi this name once represented the performance monster of the mobile phone industry, then came to this group of separatist PC community, millet can again set off a reign in a Red Sea it?
Millet laptop Air is divided into 12.5 inch set version (hereinafter referred to as the standard version) and 13.3 inch single significant version (hereinafter referred to as high version), 2 in addition to the screen size, cpu and graphics cards and other main components are different, in There are many differences between the two parts. For example, in addition to the memory size, the high-level version uses DDR4 memory and the standard version uses LPDDR3 memory. The same is true for storage. The high-level version uses PCIE. The channel is based on the 256GB SSD of the NVMe transmission protocol, while the standard version is the 128GB SSD with the normal SATA channel. The difference in the read and write performance between the two is huge. From the hardware point of view, the high-priced version of the 1000 Ocean is more expensive than the standard version. Very cost-effective. Xiao Bian also contrasted with other brands of 5,000-gigabyte notebooks, hardly found the same use of PCIE channel based on the NVMe transmission protocol SSD as a hard disk, and this compared to its use of the 940MX alone significantly, it is even more its eye-catching The pen.
It should be noted that Xiaobian has got a high-profile millet notebook Air this time, so this review is mainly focused on high-profile version. On the outer packaging, I did not forget that I used the similar packaging design of the Xiaomi mobile phone series - white + notebook main body
After opening the package, we can see that only the power adapter and the three-package description of the accessories, adapter adapt to the trend of the USB 3.1 Type-C (Gen1) interface.
The power adapter has a power of 65W, which is more conscientious than the 45W that most friends have.
Finally came to the millet notebook Air debut, millet material is still very awesome in the material used, which uses a one-piece metal body design, the surface of the anodizing process, feel comfortable but not slippery.
Millet notebook Air A surface does not have a LOGO, the official meaning is to let the user's own DIY A surface pattern, if you do not choose, A surface is a bare aluminum, slightly unexpected.
The official meaning of thickness seems to be thinner than a dollar, but given the reasons you know, Xiao Bian will not add more demonstrations.
The interface on the left side of the millet notebook Air high version is an HDMI interface, USB 3.0 interface and 3.5mm headphone jack. On the right is the power indicator, USB 3.1 Type-C connector, and USB 3.0 connector.
Overall, the millet notebook Air's shape is more crude, cross-section is almost the same across the board, there is not too much arc surface, it looks okay, but in the hands of a little bit awkward, and said a little more millet notebook Air is very easy to open and close with one hand.
The D surface of the millet notebook also uses a one-piece metal material, and it should be noted that the heat sink on the D surface is only available in high-profile versions. The standard version uses the m3+ set-up solution and consumes less power. Not slotted.
After opening the screen, you can see that the B side of the millet notebook air is made of full glass, while the C side is made of metal.
The screen has a narrow bezel design with a 1 megapixel camera and microphone integrated at the top of the screen
The C-surface keyboard has a chocolate design with a short keystroke, a harder feedback, and a medium level. Only two lights are on and off, and the user cannot adjust the brightness of the keyboard.
The power switch is set in the upper right corner of the keyboard, and it does not open independently. When the user uses the return key or the delete key, it is easy to mistakenly press the key to the shutdown key. Put the switch between the two keys with such a high degree of use. Xiao Bian can only give bad reviews.
The touchpad is made of glass and has a good sliding feel and a large supporting surface area. The user can use the touchpad to find the supporting position when using the touchpad.
Screen testing uses the CalMAN 5 Home Theater for testing, and all tests were conducted at 100 nits.
The screen has a maximum brightness of 300.68 nits and a contrast ratio of 1074:1
The average color test is 2.5, and the screen quality is very good.
The sRGB color gamut of the screen is 92.3%.
The system's MiMi laptop Air comes with Windows 10 Home Edition, so our tests are based on Windows 10 Home Edition.
Millet notebook Air high version uses the Intel Core i5 6200U 2.30GHz, 2 core 4 threads, the highest single-core can be Turbo to 2.8GHz, with 14nm process and Skylake architecture, TDP is 15W, although the power consumption is very good, but the performance On the relatively weak, the CPU-Z comparison is only similar to the 4th generation desktop I3.
8GB of DDR4-2133MHz memory
In addition to the CPU's own HD 520 set, the GPU is also equipped with the GTX940MX. Although it is an enhanced version, its memory is only 1GB from the specifications, and the memory bandwidth is only 64 Bit.
The hard disk uses a 256G PCI-E SSD from Samsung, based on the NVMe transmission protocol.
Disk performance test results
PCMark 8 Home conventional 3.0 scored 2450.
PCMark 8 Creative conventional 3.0 scored 2391.
PCMark 8 Work conventional 3.0 scored 2817
3DMark scored 1938 points for Fire Strike. Compared to most Ultrabooks with HD520, the Fire Strike score of 1938 is also much higher than the 800 points scored by HD520. Unfortunately, this score also shows that the 940MX will not be able to cope with some large-scale online games and stand-alone games.
3DMark scored 483 points on the Fire Strike Extreme. 1GB of memory became the bottleneck, and the performance dropped significantly when running at 2K resolution.
Cinebench R15 test result, OpenGL is 53.45fps, CPU is 289cb
Need to explain in advance is that the test environment room temperature is about 25 °C.
CPU temperature is 39 degrees during standby
After 10 minutes of full load operation, the CPU temperature rises to 63 degrees and the frequency remains at 2.7 GHz, which is quite good.
After the roasting machine, the full load temperature of the GPU was maintained at 58 degrees and the frequency was stabilized at 405 MHz.
Noise millet notebook Air high version with a noise meter measured standby is 44.2dB, the general performance.
When the load is full, the noise rises to 53.1dB. At this time, the user can clearly hear the sound of the fan, which affects the user experience more.
The body temperature is 36.5 degrees C on the standby surface, and 34.2 degrees on the D surface.
The maximum surface temperature for C-plane operation is 46.4 degrees for 10 minutes at full load, and 47.6 degrees for D-plane. The performance is fairly good, and the heat source on the C-plane is mainly concentrated on the keyboard, which has little effect on user experience.
Internal overview, it should be noted that although the rear cover of the millet notebook Air is easy to remove, but there is a screw under the mat, you need to remove the mat before you can remove it.
Millet laptop Air is equipped with two cooling fans, theoretically it can have a better cooling performance, but I do not know why only use a heat pipe to heat the CPU and GPU, which is a demerit, and because The two big fevers are concentrated, so even if you use a dual-fan, there are not many cooling bonuses.
The battery capacity is 5107mAh.
SSD notebook millet notebook Air high version uses an OEM version of the Samsung PM951, theoretically continuous reading can reach 1000MB/S, continuous writing is 280MB/S, reading performance can be described as brutal. However, it should be noted that the two M2 ports of the millet notebook Air High Edition are different. One side is a PCIE channel and the other is a SATA channel. Users need to pay more attention when expanding the memory.
As the first notebook released by Xiaomi, Xiaomi notebook Air is qualified. Compared with other brands of the same price notebook, there is no weakness in the hardware, such as narrow bezel design, PCIE interface based on NVMe transmission protocol 256GB SSD, etc. Price opponents are more conscientious, but on the whole, they do not give consumers the feeling of surprise, and similar laptops with similar hardware specifications also have a lot of lower prices than millet notebooks, or have better hardware specifications or design materials. As a latecomer, Xiaomi does not have any software for his own use at the software end. It also gives consumers more concerns. And millet laptop air high version of millet positioning as a light gaming game is also slightly embarrassing, and its i5-6500U+940MX equipped with most of the official game used i5-6300HQ+960M program (price is about 5500 or so) phase In comparison, whether it is the number of CPU cores, performance, or the performance of the graphics cards are all in obvious weaknesses, which makes them in a passive state from the beginning, and if Xiaomi’s slogan is an ultrabook that can play games, I believe that The effect will be much better. But in any case, for the first release of notebook millet, millet laptop Air is still full of sincerity, after all, in the Red Sea market, who are still afraid to use high-volume procurement of parts and components to reduce prices and manufacturing prices , If you use your daily work to input text, light image processing, etc., plus you want to travel outside can also pick two LOL, then the millet notebook may be a good choice.
