dell Latitude E6220 adopted Intel Sandy Bridge platform, equipped with Intel KuRui i5 2520 M processor

As people for mobile devices of the increasing demand, laptop computers have become instead of traditional desktop everybody the life and work of the indispensable as electronic products. Especially for business applications for, the popularity of the laptop to realize the real sense of "mobile office", users work area from indoor extended to the outdoors.

In the business field notebooks, many manufacturers are introduced for mobile office and design notebook products. Latitude as dell Lenovo T400 screen laptop products in the commercial high-end series, has been adhering to the superb production technology and sedate appearance design concept, this series laptop to be much high-end business people to love.

Hardware configuration, dell Latitude E6220 adopted Intel Sandy Bridge platform, equipped with Intel KuRui i5 2520 M processor, carrying 320 GB hard drive, and a single 4 GB DDR3 1333 MHz high-speed memory, in addition, the machine factory installed the original Windows 7 system. Video card, the type has used the processor Intel core of the fusion of HD 3000 graphics CARDS.

On the choice of the notebook is concerned, the second generation of intelligence KuRui processor Intel is absolutely the Lenovo T410 screen best choice, it will be very good guarantee this part of computer users fluency, also can give dual attention to the performance and the more low budget choices.

In the performance test before you begin, we first through the AIDA 64 CPUID tools to see the star KuRui i5 2520 M Intel processor of the basic information, it is based on 32 nm process technology, the core code for Sandy Bridge, 2.5 GHz frequency, in black frequency 2.0 accelerating technology help the highest frequency can be up to 3.2 GHz, and the sharing of level 3 cache for 3 MB, whole TDP of 35 W, also support hyper-threading technology and the latest AES and AVX instruction set.

The models for the 320 GB hard drive capacity, we through the HD Tune to the performance test read. Test results from screenshots can see, this type of hard disk average transmission rate is 68.2 MB/SEC, highest transmission Lenovo T500 screen rate is 94.9 MB/SEC, and minimum transmission rate is 22.7 MB/SEC, access time for 21 milliseconds, curve wave is a bit of a clear some, hard disk average readout rate performance is good, but the minimum transmission rate slightly inadequate.

As a position in high-end business notebook computer, the use of the port is easy to use, whether can reasonable human nature, of course, is also the product design in key consideration. Dell Latitude E6220 keyboard layout in doing this or a great, especially the arrangement of the rear interface for business users with a more convenient.

Dell Latitude E6220 keyboard design conforms to the commercial personage love style, knock each button feedback are obvious after, key and the distance between the key keep also very reasonable, users use does not Lenovo T510 screen appear mutual interference, although key process is a little shorter, but is sunken the arc of the very joint fingertips and typing noise control well, and orange FN combination is the design of the key usability is very high.

Dell Latitude E6220 host power button is arranged in the top right corner keyboard, a square key cabinet modelling and delicate, the surface of the metal used to grind arenaceous qualitative material, and big size of power supply logo below is white state indicator light, press the notebook normal after a kick-off meeting for appear white lights used to remind users.

Dell Latitude E6220 axis control the power of the better, one hand move back and forth, damping are proper, shaft parts adopt unique floated before yue screen modelling, the screen after declining Angle moved forward with Lenovo X100e screen the actual observation more user Angle. This machine touch board area is not very bounteous, your fingers to operate there will be a certain limitation, but the sensitivity of the pointer or better performance.

Today we introduce is a from this series-Latitude E6220, the aircraft using the does not see more of its 12.5-inch body scale, designed for often go out of business to the tailor and become, the user can not only HP dv8000 fan through the screen got good visual effect, and the more important is Latitude E6220 as well as the small portable moving characteristic. Another is that the worth, this product using the second generation of the intelligence KuRui Intel processor, its powerful process performance in business applications have more outstanding performance.

On the market at present most notebook products using Intel processor, we the evaluation of product also is such. The second generation of replacement laptop screen intelligence KuRui processor Intel has accelerated frequency farce 2.0, senior vector expand instruction set (AVX) and so on many properties, it can be an effective help users increase office efficiency.

For mobile office users, for the quality of their notebook demand is very high, as dell's high-end commercial products, these machines is also in the mold in the work under many time. These machines have high performance in at the same time is also very good appearance design aspects.

Many friends think that as long as the result is high processor is the best, however, that fact is not there. Now the processor more emphasis on functional and security, and in the two aspects, the second generation of Intel laptop fan processors have many intelligent KuRui core advantages, we also appears in the next test in the link to show.

Believe that each user does not want his laptop into a "fire", and laptop cooling is each user is concerned with. In fact, whether good heat, the processor is the key. As the main laptop internal heat source, the processor calorific value directly affects the overall size of the cooling capacity. The second generation of intelligent Intel KuRui configuration of processor dell E6220 based on advanced 32 nm process technology, its thermal design is lower than the product before power consumption, and frequency of 2.0 problems to also can HP G42 keyboard make according to the different application processor environment automatically adjust the frequency, so as to achieve the purpose of high efficiency and energy saving.

In the cooling performance test, we adopted FurMark software to make these machines in high load by mode, after an hour or so of the time, the processor temperature up to 78 ℃, the core temperature to 68 ℃ respectively and 75 ℃, only from the temperature sensor, dell Latitude E6220 cooling efficiency of the whole performance in general.

Through the hot camera, we of the body surface and the D C temperature was tested. Among them, and users most often contact Compaq CQ61 keyboard for 45 ℃ maximum temperature part, the highest temperature of 44.6 ℃ at the bottom. And from the hot in the map we can see, the red areas highest temperature, for the keyboard for surface, the red areas focus on the left near keyboard heat-sink window, and the bottom is concentrated in the fuselage of heat-sink window area, from the actual performance perspective, its overall cooling efficiency performance is still quite good of, including palm's temperature control about position is good.

Dell Latitude E6220 equipped with three core 30 Wh lithium battery, we through the Windows 7 power management estimate, can see, notebook in energy saving electricity mode, at the same time open cable network adapter and 50% screen brightness state, in the remaining 98% is three hours can power supply 52 minutes.

As a commercial notebook speaking, life time performance is good, it is mainly because the second generation of Intel processors HP dv5000 fan used the KuRui intelligent 32 nm process, its can be in more of low power consumption circumstances achieve higher performance. If there are further mobile office demand, the user can also equipment second battery life as a supplement, can satisfy users to more long use time.

Business users in the crowd, laptop have small portable airframe is very important, it can not only reduce the weight of the journey, but also can improve the efficiency of the portable office efficiency, tailor made 12.5 inches dell Latitude E6220 in these two aspects of the better.

Even more important, these machines used the second generation of intelligence KuRui Intel processor, high-performance processor to join the user in business applications can more handy, in new Intel HD 3000 with the core of video card, and can meet the daily work of the user needs.
