Notebook Sony Sa2 Review
AIO S series a total of three sub-series, the new series SA2 will belong to them
, two other small series were SD/YA2, which YA2 the scope of this product is the Internet, we shall leave. The remaining SA2 SD series is the same 13.3-inch ultra-portable full-function business machines, and are using the same mold design, but for a slight difference in the appearance of color, you want to differentiate between the two series is basically very difficult.
SA2 in the new machine to get, I have already made a detailed test SD series, because the appearance of the same reason, the next article in this part of the test will look using quick introduction with emphasis on details of the comparative form, the SA2 SD series there are differences.
The appearance
To say that the body dies, SA2 SD series is almost no difference, as are the metal body, the same are ultra-thin design. Sony SA2 of the body shell is completely crafted by the aluminum-magnesium alloy, a solid body can better protect the internal hardware, thereby protecting the user's data security. This business in the mobile portable display a high level, body weight 1.72kg, the thinnest at only 23.3mm, this slim mobile design is often tailor-made business people.
Because the two series are different for the crowd, so the product has an initial color distinction. The figure can be seen by the SA2 Series offers a black, silver, and golden brown crust, the series in color selection on the SD series is more colorful than the mature. Because SA2 series for high-end business crowd, this type of user requirements formally solemn appearance of the product, color selection will favor the traditional black on white, the other temperament shell is golden brown luxury custom models, you need to customize the user visit the official website to buy. Although the manufacturers set the series to distinguish between such users, but consumers can choose their own preferences from the main color, concept specified by the manufacturer is not necessarily their own.
Sony SA2 and SD side is exactly the same design, only a headphone jack and the left drive, and card reader, HDMI, USB, VGA and other commonly used interfaces are designed in the right side.
Configuration chapter
If the distinction between appearance was not enough, then we can compare the configuration, because the relatively high-end Sony SA2, it is difficult to find in the SD series models with a similar standard. So we use a Sony official website of the custom models, the SD series and the Sony SA2 configuration changes to essentially the same, so you can see the nuances of the two.
Difference between a screen resolution
From the configuration, two models have the same product processor, memory, graphics card, the difference is the screen resolution and weight. Under the same conditions, the screen size, higher resolution screen display with greater detail. Sony SA2 uses a 16:9 ratio LED backlit screen, the screen resolution is staggering 1600 900, to know that such a resolution 15-inch large-size models is rare.
Difference between two fingerprint reader
The high-end business machines have a very important feature is that users will be designed to provide security design, such as increased hard disk encryption, fingerprint identification systems designed to improve data security. Sony SA27GC the touch pad placed between the left and right buttons of a fingerprint reader, compared to the common be placed in the position of the right wrist rest more symmetrical appearance.
Difference between three camera
Sony Sony SA27GC and SD series models, respectively, by the resolution of 1280 1024 and 680 480 camera, that is, we often say 130W and 30W-pixel-pixel camera. Light-sensitive chip in the camera exactly the same circumstances, the higher the pixels the more clear image, so that Sony SA2 higher resolution imaging camera.
Two different series of product differentiation is very clear, in fact, can be summarized as "three high": a high-resolution screen, a high-pixel
Sony VAIO VGN-G1AAPSA battery camera (in fact, 130W pixels is not too high), a high-end business model will prepared fingerprint reader. These parts are all rigid parts, which is the official does not provide post-upgrade, whether it is worth as much money to buy depends on the user's own needs.
Having said that users want to make clear the basic differences between the two series, but also better able to choose products according to their needs. Topic back to our hero that Sony SA2, it no longer describes the appearance, I believe we already have a general understanding, then it is important to look at performance issues.
"Tough" on the word
Sony SA2 in Windows7 system self-test index was 5.9 points, its biggest shortcomings actually come to the hard disk. Can not be said that this 750GB 7200 rpm hard drive performance is not good, can only say that the performance of other parts too powerful. Improve the score's main hardware including Intel Core i7 2620M processor, 8G DDR3 memory and the AMD Radeon HD 6630M with significant independence.
Sony SA2 uses a relatively high-end mobile platform Intel Core i7 2620M processor, the processor speeds 2.70GHz, supports Turbo Boost to 3.4GHz, Intel Turbo Boost technology, the time needed to obtain higher performance. Although performance and compared to the top I7 2920XM or inadequate, but it is the Sandy Bridge architecture I7 under the lowest power mobile processors, only 35W. It can be seen in order to choose this processor performance and heat in a better
Sony VAIO VGN-G2AAPSA battery balance between energy consumption.
CineBench use of film and television industry, software development, Cinema 4D special effects engine, you can test the CPU and graphics performance. Relative to the previous version 9.x, R10 version of the last point more potential drain system, accurately reflects the system performance. Test consists of two, respectively, for the processor and graphics performance. The first test simply use the CPU rendering a high-precision 3D scene images on a single processor, single thread runs only once, if the system has more than one processor core or multi-threading, then the first time use only one thread, the first the second run all the processor cores and threads. The second test is for the OpenGL graphics performance.
Performance-based testing machine
Sony SA2 in endurance test to get a 200-minute performance, which is about three hours you can work unplugged. This result more general, but taking into account within the body in the end Core I7 + HD6630 graphics cards these two high-power hardware, this endurance performance is good. However, we must also understand that time is three hours a full-load operation in hardware mode, resulting, in fact, few consumers in the mobile environment using high-performance all-weather mode, and SA2 will have the energy conditions 6 hours battery life.
Summary
Laptop computers have a simple requirement that performance out of the era, users personalized, professional desire by businesses pay attention to it gradually. Today, manufacturers began to market segments continue to launch in line with the needs of the target population of products, these include the color, configuration, appearance, and many small details of the division, so only the Sony SA2 and SD series
Sony VAIO VGN-G1AAPSB battery so very similar series classification. Overall, Sony SA2 from the design to the internal configuration should reflect the characteristics of high-end models, counted on a very mature product. However, as a business book, it still needs to be improved battery life, after all, another strong game performance for business users, the significance is not large, as a longer life to the anti-useful.
