LENOVO ThinkPad S440 S3-S440 ultrabook coming


Lenovo ThinkPad S Series is the introduction of new products in 2012, including 13, 14, two kinds of body size, the main low-end portable notebook market, and over most of the extreme compared to although the lack of spirit, but mainstream hardware and approachable prices for consumers real benefits.

After entering 2013, both intel or AMD have launched a new hardware platform, but also to the older generation laptop replacement, we tested today for everyone ThinkPad S431 ThinkPad S440 is an upgrade, although little change in appearance, but the core hardware is completely different, ThinkPad S440 enabled Intel developed for thin and light notebooks fourth generation low-power processor, then it's about performance? How about battery life? Next evaluation to answer your questions.

ThinkPad S440 with 4cell LENOVO ThinkPad S440 Battery and S431 is basically the same exterior design, the fuselage cover is not too much modification, just like the body is very concise. In the material, subject to cost constraints, S440 does not use metal chassis, but chose the more common ABS plastic, its strength as metal lid, shake vigorously screen will appear a certain deformation, accompanied by water ripples, daily use vigorously pressed body should be avoided.

Open the top cover later, S440 keyboard surface and screen surface casing with silver-gray plastic material, though, and the dark body cap fit is good, but do not seem as bright, and some dirty feeling, and a sense of the plastic casing heavier. On the screen, S440 upgrade to a matte screen, and the glossy screen compared to the light environment can reduce the effect of reflection on the show, but he is still in use 1366 × 768 resolution display, and screen colors good, the picture looks somewhat partial gray, and there is a big gap between desktop monitors, used for general everyday office is not much problem, for image processing of color-sensitive work, it is recommended to use an external monitor.

As a main light portable products, ASUS V550CA with 4cell ASUS V550CA Battery and the same size by nearly 30 percent compared to a thin, nearly 40% lighter! Has been close to 14-inch ultra-extreme levels, but due to still use lithium batteries, so it's more than 14-inch rear fuselage alone significantly over most of the slightly thick that. ASUS V550CA entire keyboard surface is relatively simple, raised above the keyboard a battery, the power switch on the left to set up round the keyboard area above a smaller space does not set any shortcuts, save the original one button system moved to the fuselage the left.

The use of touch on the keyboard, S440 using Lenovo's unique curved floating island-style keyboard, although from the appearance of the keycaps with ThinkPad T series is somewhat similar, but the feel is completely different. Affected by the thickness of the body, S440 keyboard keys shorter, press down feel somewhat more rigid, and T-series keyboard there is a big gap, but with the same type of ultra-pole of this comparison, S440 keyboard experience was not bad. With the popularity of WIN8, most notebooks are in transition have not yet upgraded to touch our daily operation without a mouse is still need to rely on touchpad. From the use of an area of ​​view, S440 configuration integrated touchpad is indeed not small, matte texture surface display, slide your finger up and relatively smooth, but the cursor moves slower, and the touchpad buttons feel very hard, force feedback inadequate.


With laptop prices continue to decline, coupled with the Windows 8 touch technology gradually, consumers in the purchase of the traditional notebook, also began to slowly shift our attention to the low-cost touch itself. This part of the user, the actual demand does not want to chase the high performance of the hardware configuration, do not play a large 3D games, laptop use, simple response is usually the main office, on the Internet, look at the news of the type of application. And if you joined the touch screen, with Windows 8 operating system, fingers can also get a better experience.


And more slim Ultrabook compared to the fuselage slightly thick ASUS V550CB interface configuration more complete, it provides a USB3.0, 2 个 USB2.0, 1 x HDMI, 1 x RJ45 and audio interface, basically meet daily use, but the lack of VGA projector when connecting some trouble, but one can not achieve two USB3.0 USB 3.0 high-speed data transmission device directly. Hardware, ASUS V550CB with 3000mAh ASUS V550CB Battery comprehensive upgrade to the fourth-generation Core platform, he used i5 - 4200U low-power processor with AMD Radeon HD 8570M discrete graphics, 4GB memory and 500GB mechanical hard drive, then his hardware performance how? See below for the actual test results.

S440 is equipped with fourth-generation Intel Core i5-4200U has two physical cores, with four threads processing capabilities, clocked at 1.6GHz, Core frequency up to 2.6GHz, using 22nm 3D transistor technology, TDP of 15W, compared to the previous generation of U-series CPU reducing power consumption 2W, is designed for ultra-thin product launch of the CPU, a single-chip architecture, PCH chip and CPU packaged in a BGA package arrays, further reducing the overall power consumption, reduced board space.

In performance, we use CINEBENCH R10 for G405 with 6cell LENOVO G405 Battery were tested. CINEBENCH R10 test project simply use a CPU processor rendering a high-precision 3D scene screen to test out the single-threaded and multi-threaded CPU processing power. Through the test results with the previous generation of contrast, in the multi-threading capabilities, the fourth-generation Core i5-4200U is less than the previous generation Core i5 low-power processor, and the third-generation Core i3-3217U at the same level of processing performance not great, but the overall lower power consumption, can bring a longer battery life.

In performance, HD 8570M performance is not to force, its 3DMark VANTAGE E Mode GPU score of only 15,921 projects, such results in the mainstream notebook graphics cards to lower middle level, running large 3D game more difficult, but can be in response to low quality "Call of Duty 8" less demanding on the graphics card such games and the vast majority of online games. PCMark7 is 2011 Futuremark for Windows 7 operating system, the new generation of the benchmarking tool, which contains seven different test areas by 25 independent workload composition, covering storage, computation, image and video processing, web browsing, games and other aspects of everyday applications, the test results may reflect the overall performance of the tested models.

To get a better mobile portability, Lenovo ThinkPad S440-IFI is configured with only three core 32Wh 14.8V lithium battery, but by virtue of the fourth-generation Core Duo processor power control optimization, it is in screen brightness 40% in the case, its MobileMark 2012 score of office mode 290 minutes (4 hours 50 minutes) than the previous generation of products to extend more than 30%. Pager after 30 minutes after the test, the left side of the keyboard surface Lenovo S440 there is a small range of heat accumulation, the maximum temperature of 42.8 ℃, prolonged exposure to this area will be warm feeling. The underside of the fuselage, S440 cooling holes near the high temperature, but a temperature of about 42 ℃ still acceptable, just to try to avoid prolonged use of plug placed vents in the legs.

Because not equipped with SSD solid state hard drive, so the disk performance tests are more sensitive to PCmark7 ASUS K550C and ASUS K550C Battery score is not high, but the 2623's gotta show he could meet our daily needs, if the user to upgrade their own SSD, its overall operating speed will be much improvement.
