â–² The right side of the fuselage, from left to right, is the USB Type-C interface, DP interface, headset interface, USB3.0 interface, RJ45 network interface, expansion dock interface, SIM card slot, and power hole
â–² SD card slot is hidden on the edge of the D surface
After reading these interfaces, surely everyone will understand why Xiaobian called the HP EliteBook 820 G3 a notebook for business. In this era of pursuing thin and light body, it is hard to imagine a 1.89cm thick notebook. Can have such a complete interface, even to accommodate the SD card slot, RJ45 network port and VGA interface, HP EliteBook 820 G3 also made some design, attention to these details, in exchange for the convenience of business users is undoubtedly, after all If you need to prepare a bunch of patch cords while carrying a business book, it can be inconvenient to use.
For the game, performance is undoubtedly the most important indicator to measure its performance, but for the business case, performance is less important. The more important than performance is the stability and fluency of the system runtime, of course, processing The performance of office tasks is still necessary. In this regard, HP EliteBook 820 G3 has Core i7-6500U processor, equipped with 8GB DDR4 memory, 256GB SSD solid state drive, then we look at the performance of HP EliteBook 820 G3.
â–² Configuration list
HP EliteBook 820 G3 is equipped with Intel's sixth-generation Core family's strongest low-voltage processor i7-6500U, the core code name is Skylake-U, based on the latest 14nm process technology, with dual-core four-threaded and 4MB three-level cache, the default The main frequency reaches 2.6GHz, the Turbo frequency is as high as 3.4GHz and the TDP is 15W. Through the CPU-Z test, we can see that whether the single-core performance or multi-core performance, compared to the i7-4558U with a default frequency of 2.8GHz, i7-6500U has a certain increase, especially multi-core performance, higher 300 points.
Like most high-end business notebooks on the market, the HP EliteBook 820 G3 does not have a discrete graphics card that will cause heat dissipation on thin and light bodies. It is equipped with Intel Core Graphics HD520, and in the 3DMARK 11 Performance mode test, The HD520 Core Graphics score reaches P1353. It is true that this score is lower than those of high-definition discrete graphics cards, but its performance is sufficient to meet most of the scenarios that may be encountered in the business office. More importantly, it is not. It will have a negative impact on heat dissipation and endurance performance.
In order to ensure the smooth and stable operation of the machine, the HP EliteBook 820 G3 has selected 8GB DDR4 memory and 256GB SSD solid-state drive, which can meet business requirements regardless of capacity or speed, and may avoid processing large numbers of tasks. The appearance of Caton even crashed. In the random read and write tests of hard disks of CrystalDiskMark and AS SSD, we can see that the read speed of this 256GB SSD is over 400MB/s, and the write speed is also around 300MB/s. For many occasions, it needs to be used with it. For business users, this read/write speed will greatly reduce their waiting time.
We used the CineBench R15 to test the performance of the processor and the graphics card. In the R15, we can see that the Core i7-6500U processor scored 323cb. In the graphics card, the HD520 core graphics card got the FPS score of 35.75, whether it is the processor or the Graphics card, to meet the business needs of the office is completely no problem. The next thing we are going to do is test the performance of the whole machine, mainly through the PC Mark8.
In the Work environment test of the PC Mark8, the HP EliteBook 820 G3 scored 4336 points. For a thin and light business-oriented crowd, the overall performance has been able to meet a variety of office tasks. More importantly, it is obviously 8GB DDR4 memory. With the 256GB SSD, with these configurations, the HP EliteBook 820 G3 can be turned on at an extremely fast speed during use, improving the system's response speed, and it won't be stuck in multi-task switching. For business people, the stability of the system can ensure data security, allowing them to work at ease and improve work efficiency. In this regard, the HP EliteBook 820 G3 performs adequately.
Thermal test: good temperature control
As a business book, it is almost impossible to meet the need to squeeze 100% of the processor's performance during daily use. Therefore, we used the PC Mark8 to simulate the business office environment. In the PC Mark8 Work environment test, The system will continuously simulate the working environment including data processing, document input, web browsing, multi-task switching and video calls. We use the thermal imager to obtain the heat dissipation of the HP EliteBook 820 G3 when the test progress exceeds 2/3.
We can see that when simulating a continuous office environment, the heat of the HP EliteBook 820 G3 is mainly concentrated around the shaft, with a maximum stability of 41.5°. However, the keyboard surface has no obvious heating. This causes the body heat to cause problems for users during use. The impact is minimal. At the bottom of the fuselage, the heat is mainly concentrated on the heat exhaust outlet and the air inlet, but the maximum temperature is only 36.3°. This kind of heat dissipation performance is good enough for a business that needs to ensure the stability of the system, and will not be affected by heat. Used by users.
Endurance test: no problem with unplugged office
In the battery life test, we also use PC Mark8 to simulate the user's continuous office scene.
â–² PC Mark8 Work environment endurance test results
In the Work environment, the HP EliteBook 820 G3 has a battery life of 6 hours and 45 minutes. It is worth mentioning that the testing process of the PC Mark8 is continuous, that is, the contents of the PC Mark8 continuously simulate various office scenarios during the 6 hours and 45 minutes. Until the low battery automatically hibernates, the uninterrupted high-intensity work of such a long time is almost impossible in the daily work. Therefore, under normal working conditions, the HP EliteBook 820 G3 maintains electricity for 8 hours a day. There is no big problem.
Summary: The performance of an elite business
After seeing the HP EliteBook 820 G3, you will really understand that the same is the lightness of the body, what is the difference between the business and fashion books, the appearance of the fashion book may be more brilliant, more design elements, but the fashion book will often In order to pursue the ultimate thinness of the fuselage and sacrifice battery capacity, sacrifice interface configuration, or use ultra-low-power processors to reduce heat generation, business is not the same. At a thickness of 1.89cm, the HP EliteBook 820 G3 retains Extremely rich interface, powerful low-voltage Core i7-6500U processor, and the battery life can still maintain eight hours of normal work.
"Elite" means "elite". Naming its own commercial product with the "EliteBook" also fully demonstrates HP's position on this commercial product. Regardless of appearance, configuration or details, system stability, EliteBook 820 G3 There is no such thing as an "elite". For a business book, what can we do? What else can we ask for?
