Next, we tested the machine's memory and CPU cache performance by AIDA64. AIDA64 is a test software and hardware system information tool, it can be shown in detail in every aspect of PC information. AIDA64 not only provides functions such as hardware debugging, assist overclocking, pressure testing, and sensor monitoring etc., but also can conduct a comprehensive assessment of the processor, system memory, and disk drive performance. From the above results, we can see the NP7256 16G DDR4 SAGER of the super high speed memory and CPU cache performance is quite good level.

HP ProBook 440 using the more rich sense of science and technology of pattern to be decorated, with black and red color style, looks cool. In the disposition aspect, though the fourth generation Core i7 and GTX 950M sole combination of isn't the strongest, coupled with the price of only 5999 yuan, its performance in terms of price is still very prominent.

On the interface, ProBook 430 has a very rich choice. Lightning interface arrangement on the left side of the fuselage with the RJ45 network interface, VGA interface, HDMI interface, USB3.0 interface and a TYPE-C, a 3.5mm headset port.

First look at the I5-6300U this low voltage flagship CPU performance bar. Thanks to the advantages of 14nm process and Skylake architecture, the actual performance of this low voltage CPU even stronger than the Haswell era star I5-4200M CPU.

In the performance test, small hand HP Pavilion 17 although not top with I7, but because of the strong performance of GeForce 940M and I5-6300U, the overall test results are very good, not only can fully meet the daily office work, some of the less severe plane design task can also be by virtue of the large capacity DDR4 memory support.

High quality HP PA06 battery on sale,Today's test of Pavilion 17 is only equipped with a SSD+1TB HDD 128G hybrid hard drive, provides a quick boot and the game is based on the 1TB mechanical hard disk and provides sufficient game storage space for the game players.

Generally speaking, HP ProBook 470 notebook is fairly thin, so it is very convenient to carry. HP ProBook 470 notebook design of a little ugly, although not pretty but durable. It has 3 cloth on both sides of USB port, USB port 2 and DVD CD-ROM. As already mentioned, HP ProBook 470 is equipped with sixth generation Intel core i7-6700HQ processor micro architecture based on SKYLAKE, frequency is 2.6GHz, than Intel to the top of the 2.9GHz core i7-6920HQ slightly inferior.

HP ProBook 455 G4 appearance follows the classic design style of the previous generation products, calm and stylish, and have good portability, this point is particularly important for business. In addition, HP ProBook 455 G4 on the security of user information is also very hard, in order to better protect user privacy in the fingerprint recognition module. Overall, HP this product for business people is still relatively good, has a good performance is relatively portable, very suitable for mobile office use.

We usually use portable to measure the thickness and weight of a notebook, a coin diameter is 25mm, through the machine can be seen on the contrast, the thickness and the diameter of the coin is very close, but in fact this coin is slightly narrower than the confidential point. Weight, the weight of the machine for the 2.260kg, travel weight of 2.663kg, overall, the machine is still very good portability.

Next, let us look again at the DELL Inspiron 7460 D, believe you see photo above the first time will is its eyes honeycomb shaped into wind grid and pentagonal subwoofer attracted. In addition, a simple triangle stepping can still be seen Inspiron 7460 design intentions detail is still one of the DELL winning a magic weapon.

DELL Inspiron 7460 P 3D in Mark 11 (middle level) under the mode of score of 4492 points, test scores before and not much difference, the scores in the game which is in the upper level. If the test software can not directly show its strength, then measured the next part of the game can be better to let everyone have a detailed understanding of DELL Inspiron 7460.

On both sides of the fuselage is the reattachment region. For most of the users are accustomed to consider, on the right side of the fuselage with a CD-RW drive and a USB2.0 interface and the rest of the interface are arranged on the left side of the fuselage; the interface on the left contains two USB3.0 interface and an RJ-45 cable network interface, a HDMI interface and a VGA interface, to close to the director of the rotating shaft about 7cm is the cooling air outlet, such a design does not affect the user.

DELL Inspiron 7560 upgrade space is not rich, it is equipped with two DDR3 memory slots highest user can extend to 16GB memory, also can be the CD-ROM position is changed to the second disk position. DELL Inspiron 7560 may not be a cost-effective outstanding products, Intel processor and +AMD graphics hardware collocation is full price. But DELL will as in the past outstanding workmanship and exquisite design to IdeaPad, with the price of the product, the Inspiron 7560 is a simple one.

Overall, the Latitude 3379 in modeling with the first generation of products have a strong succession, but is more craftsman's spirit, on both sides of the panel position at the bottom of the fuselage has certain radian, but not like the MacBook Air that strongly sharpened front end. The overall design style of the fuselage minimalist atmosphere, in some of the fuselage logo processor on a similar "watermark" of the processing.

Latitude 3379 C face is still the use of leather material, the texture of the original texture of the raw leather, the overall feeling is very comfortable, the wrist on the top is very comfortable, this is consistent with the YOGA 4 Pro. Latitude 3379 keyboard is still using a white backlight design, Fn+ space keys can be turned on or off the keyboard backlight, backlight brightness does not have multi-level adjustment mode. Hand, YOGA Latitude 3379 710S metal cap is not only a very large area, can ensure the percussion feel good.

After a period of testing, DELL Latitude 12-7275 as a business in a series of combo devices, small volume, convenient to carry; function to satisfy most users use business scenarios experience; a variety of interface, enhance the adaptability of the equipment; the built-in Windows 10 operating system more in line with the user's habits; interaction multimode, also further improve the overall user experience, is a successful windows tablet computer, now this product, DELL also is pretty good for Microsoft to effect!

Before that, DELL Latitude 12-7275 can support multi touch screen, users can achieve a simple touch of the finger in equipment operation. On this basis, the matching stylus also gives users a sensitive and convenient interactive experience, it is necessary to pay attention to the need for additional purchase.

Partial specifications, Inspiron 3456 built 14 inches, 1600 x 900 resolution screen, internal match Intel Core i7-5500U processor (2.4 GHz - 3.0 GHz), 8 GB of DDR3 memory and 256 GB SSD hard disk. The safety part, Inspiron 3456 in addition to built in palm vein recognition system but also support BIOS lock, hard disk lock, anti-theft lock socket and a Trusted Platform Module TPM.

Partial specifications, Inspiron 3555 built 13.3, igzo screen resolution of 2560 x 1440 paired with Intel Core i7-5600U (2.6 GHz - 3.2 GHz) or Intel Core i7-5500U processor (2.4 GHz - 3.0 GHz) support the highest 12gb memory and matching 256 GB SSD hard disk, also support LTE 4G high-speed Internet access.

Inspiron 7778 has a unique thermal design, the machine is equipped with two different sizes of fan, compared to single fan cooling effect is increased by 30%, and has intelligent control system, can effectively reduce the noise, 25%, near silent operation. At the same time, through the built-in temperature control master software, you can achieve a key to dust, to help clean up the dust inside the radiator. This is very close.
