The keyboard is a new generation of the ThinkPad change the largest local for most of the Think and old customers, part of the new line of chocolate keyboard keys to change so that they could not get. On the use of the experience, we can not worry about that because of the new chocolate keyboard follows the traditional keyboard of the previous generation X-type bracket and drum-type structure, the keyboard feel and traditional keyboard less.
The new Think keyboard constructed before the product design not vary that much, the same X-type bracket and drum-type structure, the key process and rebound dynamics are quite traditional keyboard design. In addition, new sub-Island-style keyboard design also uses a more lenient button surface area, arc-shaped structure is also designed better fit finger. However, after the update the keyboard shortcut keys, and some function keys to achieve than the previous generation 7-row keyboard has some flaws, but there are some small changes in the functional Think of the old user.
The shortcomings of the keyboard typing sound larger than the chocolate keyboard, In addition, we also found on the keyboard with TrackPoint (TrackPoint) and U series, the space on both sides of the keypad is not able to make good use of the current crop popular keyboard backlight is not equipped with, but the user can open the top of the screen similar to the ThinkLight keyboard light to achieve the lighting.
Keyboard finished, we look at paragraph ThinkPad touchpad, the new Think S series uses a 16:9 screen ratio, compared with an earlier version of ThinkPad products smaller body width, and this has led to the keyboard area the space beneath the tight, independent left and right touchpad buttons narrowing is for this reason. About these two keys feel soft and relatively narrow, and the feeling of use is not very good.
NVS 5400M discrete graphics, NVIDIA business-oriented notebook launched a professional grade 96 CUDA cores, support for DisplayPort display mode in game performance, the level of NVS 5400M and the previous generation of NVIDIA GT550M home entertainment graphics, 1366 × 768 resolution can provide a more smooth running mainstream 3D games. From some of the above test results, positioning as a high-end business notebook, the ThinkPad X1 Carbon machine performance to fully meet the demand for office applications, and NVS 5400M professional graphics card also provides a good 3D graphics performance. If the user wants to be more robust performance, you can also replace the faster SSD solid state drive.

Lost Planet 2 graphic characteristics: 3D APIs: the DX11; Lost Planet 2 test settings: are adjusted to 1600 × 900 resolution, and the remaining settings are Benchmark default; Lost Planet 2 test method: run multiple times Benchmark averaged. As the "Lost Planet 2" for the pure DX11 game, so the hardware requirements are higher, there is little mobile platform-independent graphics card to run smoothly the game by viewing the final results of the frames, can also be found SAMSUNG NP300E5X in the The game's performance has been outstanding. Resident Evil 5 graphic characteristics: 3D APIs: of DX10; Resident Evil 5 test settings: are adjusted to 1600 × 900 resolution, and the remaining settings are Benchmark default; Resident Evil 5 test method: run multiple times Benchmark average. Is still the resolution is set for the best 1600 × 900, other options are Benchmark default, SAMSUNG NP300E5X no pressure, you can run smoothly, but still less than the highest S-Class.
The the SAMSUNG NP300E5X specifically for Chinese users to create, the reason is that users in China is particularly fond of the 14-inch laptop, its debut in Sandy Bridge platform launched last year with the release of Ivy Bridge processor NP300E5X in the mold change based on the chip upgrade. It is worth mentioning is the flagship gaming notebook, the graphics card configuration NP300E5X performance is still disappointing for such a "high profile" models, the GTX, level graphics card in order to phase contrast with his.
In addition, the front of the fuselage design of the conventional multi-media card slot and three status lights. This hidden style design, is also the author has always respected, but also does not affect the usefulness of C-face style is more uniform, especially when used at night will not be superfluous light disturb, and once again reflects the notebook humane side. HP 655 in the back of the heat is also very comprehensive, rich vents to maintain temperature control in machine operation, a high degree of moderate Ottomans also increased the bottom of the cooling space, additional ventilation efforts.
As long as the notebook is thin nature, often most concerned about the introduction of the heat dissipation problem, the cooling is good or bad will determine the performance of this thin product life time, heat dissipation and battery life two are closely related, notebook manufacturers are also in this regard under the foot effort, I believe the concern SAMSUNG ultra-pole of this user also very concerned about its cooling performance. Pass the test, the SAMSUNG 300E with 9cell SAMSUNG 300E5X Battery ultra-pole the cooling performance is excellent (The photo shows an alternating current, 30 degrees Celsius environment, run FurMark one hour after the thermal images), taking into account its flagship mobile office to handle Office, send and receive e-mail, web browsing applications, so should have better performance on the temperature control.

The hard drive test. The discrete graphics NVIDIA GeForce GT 640M LE the SAMSUNG NP350V5C equipped 640M of the emasculated version of the actual performance is less than the GT 550M, and the positioning of but SAMSUNG NP350V5C of mobile commercial office, after the intense work to relax NP350V5C also can be easily qualified.
SAMSUNG books has never been let you down, from the design to the actual experience can be described as exhaustive. SAMSUNG NP350V5C as 350V4C range of upgrade products, although in appearance continues the fine tradition, but NP350V5C abandon some of the original elements, but made a new attempt and new changes, changes to these details we see the SAMSUNG in the design of the product, is indeed more consideration to the consumers use feelings. For consumers, the mobile office needs, SAMSUNG NP350V5C notebook is indeed worth considering.
The GATEWAY NE51B does not come with discrete graphics, but the choice of the Intel second-generation Core i7 processors in the Core Graphics as the game graphics solution. Core Graphics is not only power consumption than discrete graphics greatly reduced, while also providing more than the NVIDIA GeForce GT 310M, ATI Radeon HD 5470 this type of entry-level discrete graphics more powerful gaming performance. From the price of other brands of notebook in less than 4000 yuan of view, the majority, but also is equipped with Intel Core i3/i5 processor and above entry-level discrete graphics, we can say that the GATEWAY NE51B in these notebooks have a huge advantage in the performance.
GATEWAY NE51B using a single 2GB, frequency 1333MHz stiffness core (Goldenmars) memory, the memory read speed 10097MB / s write 10400MB / s Copy 9739MB / s memory latency time 57.6ns, regardless of memory size and speed can effectively support the day-to-day application and operation. As the core graphics card does not have dedicated graphics memory, but to share system memory and CPU, so closely related to the system memory and set explicit performance. Memory capacity and the performance of the Core Graphics, but the memory bandwidth is very large impact. Such as single-channel system memory 64-bit bandwidth, dual-channel can provide 128bit bandwidth. So if you want the core graphics card to play a bigger game graphics performance, the GATEWAY NE51B another memory slot can add with a frequency of 1333MHz, 2GB of memory.
The costs of the GATEWAY NE51B is a Samsung 320GB 5400 rpm hard drive. For most laptop users, install the games, download video, store photos 320GB fully sufficient, with an average read speed of 71.7MB / s to meet the needs of ordinary users. If the user upgrade needs, you can easily upgrade their own.
The advantage of the GATEWAY NE51B : handsome appearance, with the impact; high overall performance to meet most of the pursuit of performance for notebook users; USB3.0 interface to bring high-speed data transmission. Disadvantages: inadequate graphics driver support is not good for some games. After reading this article reviews the advantages and disadvantages, we all have a certain understanding of the GATEWAY NE51B . From the performance table, the GATEWAY NE51B midrange notebook or can absolutely dominate the mainstream notebook performance. Can be seen that the high cost of the NE51B's overall power consumption, battery life, as well as the price of $800.
Although the details of the design, there are still some regrets, but it is undeniable that the GATEWAY NE51B battery this the cheapest Intel's second generation of the cost of the Core i7 Core Graphics notebook is outstanding, with 14-inch mainstream laptop features, is a more all-round notebook . Not long-term need to play the big game, general office and learning needs to accept some minor flaws and buy this budget users, less than 600 dollar, the GATEWAY NE51B is indeed a strong value.
The Core Graphics only relatively low-end graphics capabilities can be seen from the GPU score in 3DMark, and its transition to practical application, more support for 3D games. Out to the point of view of practical application to test the machine's graphics capabilities of consideration, we selected a variety of 3D games to be measured, this being both a game of Street Fighter 4 this low load levels , including Lost Planet 2 high load game.
Heat test at room temperature of 24-25 degrees, the same base and power test, 30 minutes later investigated using infrared probe Wenyi multiple locations, the highest temperature of the body surface. From the above picture, we can clearly understand that the NE46R in addition to the high power consumption, cooling facilities, has not done very much in place up to 49 givers, in addition to the side outlet of the heat, the temperature of the keyboard surface and the bottom of the fuselage in the human body below the temperature for daily use will be very cool and comfortable.
The NE46R smaller body, and the touchpad is small, the above there are some floating-point used to enhance the friction around the keys feel in general. In addition, the location of the right palm care, also designed a biometric fingerprint reader. Details, all-alloy hinge design is a major feature of the NE46R body, ensure the life of the screen opening and closing, in addition to the top right of the C side of the two functions shortcut keys, respectively, for a mute button and APS hard drive protection switch in the C surface the left side of the curved arrow keys can open the GATEWAY Solution Center, the user of the machine system checks, security settings, and other operations.
Interfaces, in NE46R with 6cell GATEWAY NE46R Battery and the left side with a headset microphone-in-one interface, and a USB3.0 interface, an RJ-45 Ethernet card interface and power connector, the NE46R body smaller has not equipped with CD-ROM with some channels to purchase NE46R comes with an external drive. The right side of the fuselage, you can see the cooling air outlet, a VGA video input port, an HDMI interface and a USB3.0 interface and a eSATA/USB2.0 dual-use interface, HDMI-NE46R different from the U-series place of the X series, the other in front of the fuselage, also designed a multi-card reader interface.
