For some computer administrators, mini-mainframe is also very popular, because it can easily realize single-machine multi-user. After deployment, it is very convenient to manage any application or driver on the device.
Next, we will introduce this HP EliteDesk 800 G2 DM mini-host, which is called "professional". Although HP has always enjoyed a good reputation in the industry for its stable, safe, efficient and excellent integration scheme, there is a saying that "seeing is believing" and what you see with your own eyes is the truth.

When I first met HP EliteDesk 800 G2 DM, it is estimated that few people would think of the computer mainframe, because it is really too small and must be accurately described, which is equivalent to an eight-port router. The pure black appearance gives a professional feeling. It is heavy to hold in your hand, and the fuselage skeleton is made of high-strength alloy. When the fingers press the fuselage hard, there is no deformation at all. The corners are fine, and the edges are completely motionless. In the process of operation, the noise of the fan is very small, and most of the heat is emitted from the upper part. You can see the scattered heat dissipation matrix. ?
Standard bracket can erect the main engine. The advantage is that it saves desktop space and is more conducive to heat dissipation.
As for heat dissipation, you really can't blow by mouth, and the standard of commercial hosts is often very high. HP EliteDesk 800 G2 DM has undergone 120000 hours of durability test. In addition to the excellent quality of its components, it will not accumulate too much heat inside.
There is a rubber pad when lying on your side, which can increase friction and prevent the fuselage from sliding on the table. The manufacturer also reserved four fixing holes on the back, which can be easily hung on the back of the LCD and disguised as an all-in-one machine with special hooks. Connecting it with other modules can also achieve functional expansion. HP business computer small ecosystem includes expansion modules (such as DVD drive, expansion interface, etc.). ), display related accessories, etc. , compatible with all products of HP business desktop mini-series. ?
Interface: quite a few.
Although I have successfully lost weight, it is a computer after all, and scalability is the key. In addition to the two USB 3.0 interfaces on the front, there are also headphones and microphone interfaces. The launch of USB Type-C was an accident. Now more and more devices use this interface, which is far-sighted.
There are no fewer interfaces on the back than standard-sized desktops. You can see a set of DisplayPort, VGA, HDMI and video output. Don't worry. You can take all kinds of products and set up dual screens. In addition to four sets of USB 3.0 interfaces, serial ports are reserved for connecting some special devices. RJ-45 network port is definitely not redundant. In many large companies, the control of wireless networks is very strict. In order to prevent the intranet from being invaded, key departments still use network cables to connect.
However, the small one is not good. HP EliteDesk 800 G2 DM can be stuffed into the bag and taken away. Therefore, for safety reasons, the designer added a keyhole interface.
Notice the small square protruding from the back? In fact, there is an antenna inside, because the motherboard comes with a wireless network card and a Bluetooth module. Considering that the metal shell will block the signal, this is a small tail. Although I am in the conference room, the router connecting the office area is full of signals, which is more powerful than the mobile phone.
Through the cooling hole, the pure copper cooling fin at the tail is reassuring and can be called the real thing.
Accessories: They are all wireless.
Mini body must be equipped with wireless keyboard and mouse, and the grid is full.
Chocolate keyboards have become very popular, and the keys only need a little force. In addition, the suspension key has good flexibility, more comfortable feel and convenient cleaning.
The existence of the receiver means that Bluetooth connection is not adopted, but 2.4GHz wireless technology. Its advantages are stable connection, low delay and low power consumption. The disadvantage is that it takes a long time to occupy a USB interface.
Performance: More powerful than you think.
Although I didn't see the small label of Win 10, it was not easy to upgrade, and everything was free.
Even more striking is the label of Core i7 vPro. What does vPro mean? Simply put, it is a set of remote management scheme combining software and hardware introduced by Intel, which mainly includes three core parts: CPU, motherboard and firmware. Greatly enhanced the manageability of PC, to what extent? Almost all maintenance work can be done remotely, from installing software to reinstalling the system, without going to the site at all. Yes, you don't have to go to the scene to reinstall the computer. No wonder many group buying administrators like it. Now you can finally sit on the bench.
As a mini-host, it didn't sacrifice performance because of slimming, and the hardware still meets the standard of desktop. Desktop versions of Skylake Core i7-6700, 4GB DDR4-2 133, 128GB+256G are adopted to support expansion, expansion and expansion. Important things must be said. Allows users to add memory and hard disk, supports tool-free disassembly, and can easily push open the entire top cover of the fuselage by loosening the fixing screws behind the fuselage.
The processor Core i7-6700 is also a luxury configuration, and it costs 2300 yuan to buy the original box separately. The only difference with i7-6700K is overclocking capability. Finally, when 14nm appears, the power consumption decreases under standby and light load, which is equivalent to 22nm power consumption under full load. However, the improvement of performance is largely due to the improvement of frequency.
The running score has surpassed i7-4750HQ, which is equal to i7-4790.
In the chess test, i7-6700 scored 30.62 times. In terms of performance, compared with the i7-4770 with Haswell architecture, the i7-6700 has been greatly improved.
One of the most important upgrades of Skylake platform is to support DDR4 memory, which is more frequent and consumes less energy than the current DDR3 memory.
However, the more advanced DDR4 memory has not brought much improvement to the Skylake processor. To be honest, the performance bottleneck of Intel processors is not memory, but hard disk. This mini-host uses a solid state drive.
Core i7 6700' s built-in HD 530 core graphics card has 24 execution units, and the highest working frequency reaches 1 150MHz. Compared with the previous generation Core i7 4790K(HD 4600), its theoretical performance is improved by about 35%. This is the ninth generation core graphics card, which belongs to GT2 class of Intel. The sub-slicing unit structure composed of 8 execution units is adopted, which increases the support for functions such as "multi-layer coverage", "memory color stream compression" and "camera pipeline". Simply put, it greatly improves the execution efficiency. It already supports 4K resolution and supports 4K video hardware decoding. Although special effects can't be fully turned on, mainstream online games can run smoothly. ?
The score of CINEBENCH R 15 is a little higher than expected, the CPU is multi-core 8 12cb, and the OpenGL frame rate is 40.6. Playing LOL efficient spring water can have more than 100 frames.
3DMark's Cloud Gate is mainly used to test the performance of notebook computers and ordinary desktop PCs, with a score of 7354, which is quite good.
PCMark7 contains a large number of different test items to measure system performance from different angles. The score of 5772 is far behind many notebooks.
Samsung's SSD is very powerful, with an average reading speed of 926MB/s of128 GB.
However, the performance of 256G SSD is relatively low, and the reading speed is only 440 m/s.
Evaluation summary:
At present, the development of mini-mainframe is constantly being injected with commercial genes to seek a breakthrough, which is also related to the current environment. The operating costs of enterprises are getting higher and higher, and it is necessary to "reduce the burden" from all aspects. As far as office PC is concerned, it requires smaller space, better usability, higher office efficiency and lower management cost, which is precisely the strength of mini-host. Perhaps the HP EliteDesk 800 G2 DM is not the best configuration at present, but it has a stable appearance, top-level industrial design and ecological expansion system, and the configuration is targeted, which can meet the daily office needs, and has strict requirements on operation stability and data security, and its expansion ability is not even inferior to that of some mini ATX models. As long as the pricing is appropriate, it will definitely open the enterprise market.
