The novel coronavirus pneumonia is becoming more and more important.
has been more and more important in the field of telecommuting and collaboration. Especially after a new crown pneumonia outbreak this year, people have been more aware of the importance of more advanced office methods. For entrepreneurs, white-collar workers and small and medium-sized enterprises, a computer with high performance, high stability and high-quality after-sales service will help them to work efficiently. For this reason, HP has divided its products into a “war series” to bring high-end business experience to entrepreneurs. < / P > < p > HP’s “war series” has attracted the attention of the majority of users since the launch of the “war 66 series” notebook in 17 years. The design of this series is really in line with the needs of most Chinese people. In the case of providing a good experience, the price is also very appropriate, and many users feel “really fragrant”. The new product “zhanx Ruilong edition notebook” is positioned as the high-end business book of the war series. Although it is positioned as a high-end business book, the price of the series is only about 5000 yuan. I began to doubt whether it is really enough to be called “high-end”. However, after a series of evaluation and use experience, the author thinks that it plays the role of “high-end business book”. HP and X are currently top-notch in business scene application and remote collaborative office. For example, the noise reduction scheme of 88 degree wide-angle camera with 360 ° noise reduction microphone brings comfortable remote conference experience, infrared IR and finger The pattern recognition module not only improves the security, but also brings more convenient login experience, as well as a series of designs to improve the experience and office efficiency, such as silent keyboard, quickdrop fast transfer function, programmable keyboard, etc., which will be introduced in detail by the author below. < / P > < p > This release of the warx Reebok edition notebook has 13.3 inch, 14 inch and 15.6 inch three models. In terms of processor, there are AMD ryzen 7 Pro 4750u and ryzen 5 Pro 4650u. This evaluation is a 14 inch model, and the processor is AMD ryzen 7 Pro For the 4750u version, other configuration can be seen in the table below, so we won’t repeat it: < / P > < p > HP and X have a very good texture. It uses all metal body, which makes it feel slightly cold. The appearance design of the whole machine is also very simple and capable. And it’s not heavy. It’s a 14 inch product. The actual weight of the laptop is only 1.36 kg, which is lower than the official propaganda. In addition, the power adapter is only less than 1.69 kg, which is very portable. < / P > < p > its A-side style is very simple, and most people may not notice a detail – it has a small hole near the opening, which is a radio hole. HP zhanx is located in the high-end business book, so it has made a lot of efforts in the application of video conference. In order to have a good remote conference experience, HP zhanx has designed a wide-angle camera with a call noise reduction scheme. The built-in camera has a 88 ° wide angle, which can obtain a larger field of vision, which means that users have more space for activities in front of the camera, and the hardware support of radio is enhanced HP noise cancellation noise reduction solution, combined with hardware and software, can maximize the human voice, reduce environmental noise, and make the information exchange more accurate and smooth in the process of meeting. < / P > < p > in addition to the bright spot of wide angle, this camera also adopts the anti peeping design of physical paddle to ensure privacy, and has an infrared recognition module to support face recognition function. In terms of specifications, the resolution of this camera is 720p. < / P > < p > the notebook can be opened and closed with one hand, and the opening and closing angle can reach about 170 degrees. The B-side screen also accounts for a large proportion, and the borders on both sides are very narrow. Because the camera, antenna and microphone are arranged in the upper border to pass the Skype audio test, it will be a little wider, while the lower border is too narrow, otherwise the whole screen will sink and cause uncomfortable viewing So the bottom border here is the normal width. These designs make the 14 inch HP and X reach 85% of the high screen. < / P > < p > the classic pointer bar design can be seen in the middle of the C-plane keyboard, and the left and right buttons on the upper edge of the touch panel are another set of interactive modes independent of the touch panel. The area of the touchpad is good, and it has multi touch function, which can support some gesture operation. After a period of typing experience, the keyboard gives people the feeling of moderate feedback, and the key range is also good in notebook. < / P > < p > in particular, the keyboard of HP and X is very quiet, which makes it possible for you to use it without scruple in any situation. For example, you can record while listening at a meeting together without affecting the speaker. According to official propaganda, the keyboard can achieve such an experience because of the addition of improved rubber dome and shockproof hook technology under the key cap, providing constant feedback and optimal comfort, as well as a silent experience. < / P > < p > and there are many convenient or intimate designs for this keyboard. For example, the F12 key, in addition to the normal operation of F12 key, can be set through the built-in HP programmable key software. It can be set to open files, websites and software, and can be combined with ALT, Ctrl or shift and F12 to customize more functions. < / P > < p > for example, here I set to press F12 to open the EXECL program and the home page of super energy network, press ship + F12 to open Notepad program, and press Ctrl + F12 to open the installation file of Sirui peripheral driver. The effect is shown in the following figure: < / P > < p > in addition, this keyboard can adjust the brightness of the back light, and the adjustment method is also very simple. The logo of keyboard light can be seen on the F9 key By repeatedly pressing F9 key, you can switch between high brightness backlight, low brightness backlight and off, so that users can use low brightness backlight to save power and improve endurance at night, and turn off backlight completely when they don’t need it. < / P > < p > intimate design, such as the power key, if you are careful enough, you will find that the trigger force of the power key is different from other keys, and you need more force to press it. Such details are also in order to avoid users accidentally encounter the power key to cause sleep or shutdown, affecting work. Such a variety of details are the reason why a high-end business is different from ordinary products in its excellent experience. < / P > < p > the right side of HP war x keyboard area has function keys such as page turning, so the keyboard operation of HP and X is more efficient than the ordinary 60% keyboard, and the direction key is compact design. The left and right sides of the keyboard area are the speaker positions. The sound effect adjustment is in cooperation with B & O platinum. There is a fingerprint identification module in the lower right corner to facilitate fingerprint identification login. < / P > < p > in the side interface part, there is a safety latch on the left and two USB 3.1 GEN1 a ports. One of them supports power off charging. In addition, there is a headphone microphone 2-in-1 interface. On the right is a traditional round hole DC power interface, an HDMI interface and two full-function usb-c interfaces. The standard power adapter of HP and X is usb-c interface. Any one of the two usb-c ports can support the maximum charging power of 65W. < / P > < p > in addition to the traditional file transmission through the data interface, HP zhanx also has its own quickdrop fast transfer function. After downloading the corresponding application on the mobile phone or pad, open the quickdrop application on the computer side to scan and pair, and then drag the file on the computer side to the quickdrop application to easily transfer the file to the mobile phone or pad. < / P > < p > the author tests the performance of this HP war x with pcmark 10. During the test, the system power option adopts the factory preset HP optimized mode, and the others adopt the default settings. The results are as follows: < / P > < p > this HP war x adopts AMD ryzen 7 Pro 4750u this eight core 16 thread processor, and with 16GB DDR4 memory and 512gb m.2 SSD, the overall configuration is quite high. The basic productivity of these applications is very good, such as web application writing, video conferencing, web browsing, etc. < / P > < p > but in photo editing, rendering and visualization, which have certain requirements for graphics card projects, also performed well, thanks to the AMD radeon RX Vega 7 core graphics card. As a product mainly for mobile office, the overall performance of HP and X is strong enough. < / P > < p > CPU performance tests include Sandra 2020, several theoretical performance tests and some CPU creativity tests. They are also tested in the factory preset HP optimized mode, and others are set by default. The test results are shown in the following table: < / P > < p > the built-in processor of HP battle x business book is AMD ryzen 7 Pro 4750u, a low-power processor with eight cores and sixteen threads, is manufactured in 7Nm process. The maximum frequency of a single core can reach 4.1ghz, with 12MB three-level cache, and TDP is a typical 15W specification. However, HP and X have unlocked the long-term and short-term Rui frequency power to 25W and 30W respectively, enabling AMD ryzen 7 Pro 4750u to fully release its performance potential. < / P > < p > from the test results, the power consumption of long-time frequency is unlocked to 25W ryzen 7 Pro The performance of the 4750u is very strong. Let’s take the core i5-9400f desktop processor, which has a large market share, as a comparison to illustrate the processor performance of the HP and X Business Edition: in terms of single thread performance, the processor performance of the HP and X is comparable to that of the core i5-9400f desktop processor, while in terms of multi thread performance, the processor performance of the HP and X is superior It can be a third stronger than the core i5-9400f on the desktop. < / P > < p > from the test point of view, the 512gb m.2 SSD built in HP zhanx is a high-end SSD, and its read-write performance has been limited by the bottleneck of bus speed. Generally speaking, most of the mainstream price notebooks are only equipped with mid end SSD. Although there is no obvious difference between daily use and high-end SSD, when copying and writing a large number of files, the experience gap between them will be obviously widened. HP and X have the current top-level disk performance, which can make users have a good use experience in any situation. The screen quality of HP battle x is also amazing. This is an IPS screen with 1080p resolution. According to the test, its brightness reaches the official propaganda of 400 nit, and the average brightness is 410.7 nit. It should be noted that HP and X is equipped with a light sensor near the camera at the top of the screen, which can detect the light intensity nearby, and then automatically adjust the screen brightness. It is very good, and the screen also has anti glare effect. < SP > < SP > in addition to the high-end RGB screen, users can accurately see the high-end color, even when using the RGB screen. < / P > < p > although the graphics card of HP and X is the core graphics card, which is integrated into the CPU, we still use single bake CPU and single bake GPU test to simulate the scenario of high load application of CPU and high load GPU respectively, and finally double bake to simulate the most demanding use environment. Standby temperature is taken from the laptop boot
