Acer Aspire 4349 has GT540M and intel Core i5-2410M graphics processor comes with the HD3000 Core, dual graphics cards can be automatically switched, HD3000 Core graphics applications such as video transcoding has advantages, and lower power consumption, help enhance notebook battery life. However, auto-switching dual-graphics technology, sometimes not so Emmanuel, when you need discrete graphics systems with integrated graphics is still the case also occurred, and perhaps this is the Acer Aspire 4252 Core shielded HD3000 graphics card, a reason for it, although all GT540M graphics card will have to rely on power control difficulties, but the Asus rely on advanced power management technology (Power4Gear) will not be far behind.
Storage systems are used a single 2GB DDR3 RAM, and 500GB 5,400 rpm laptop hard drive, for the general running 32bit operating system users, business users, such as memory capacity sufficient to meet the vast majority of mainstream applications, and running some large commercial software applications, but we recommend users to upgrade the memory to 4GB, to better adapt to the future period of time may increase the load of applications.
Systematic assessment comes from the WIN7 Acer Aspire 4252 achievements of the final score of 5.5 points, the memory sub-items of the lowest scores, a comprehensive performance bottleneck. The Aspire 4349 is the lowest scoring items in the graphics processing, which is dual nVidia cards automatically switch the evils of, Win7 index test does not automatically call GT540M graphics card, but only comes with SNB Core processor graphics card, so making the graphics sub-project only a 4.8, in addition to the objective reasons outside, Aspire 4349 is the bottleneck in the memory, the memory will bring increased visibility significantly improved overall performance.
In this test session we will maximize the user to imitate the actual use of the environment on two notebook models for testing, we used the software used to operate and time. Test items include: file copy, compression, decompression, image batch processing, video transcoding, anti-virus software scan time.
File copy, compression, decompression, respectively, of a single large file test, and operate a large number of scattered small files, a single large file is 3.67GB, and the other is the total capacity of 4.61GB of 4985 fragmented files, the use of artificial means for timing, a copy comes for the Win7 system, compression decompression software Winrar 4.00 version;

Battery life tests, we mainly use the Mobile Mark2007 software to simulate the daily production of other major office and multimedia applications to conduct a comprehensive assessment of endurance capacity. MobileMark 2007 is a notebook based on real-world battery life and performance evaluation software.
Actual power consumption and heat test: We use UNI-T UT71E intelligent digital multimeter for testing equipment, tested this product in the three state power consumption. Were determined to connect the power but not turned on (not loaded), the boot is completed, no action within 5 minutes, but do not sleep (non-charge state) and the boot is completed, the processor at full load, the maximum throughput of the disk to work (non-rechargeable state), the power situation.
In the test, we close the screensaver, sleep, and set the battery and the system are the highest performance model as a test basis, Acer Aspire 4349 comes standard with battery life of 314 minutes, while the Acer Aspire 4252 standard battery life time of 243 minutes , a difference of 71 minutes, about an hour. Taking into account the practical application of generally continuous high load applications will not be the case, coupled with strong Asus power management technology, we believe that this gap will be reduced. Even the 243 minutes of battery life, has also been able to meet most requirements of the user's life, after all, a large high-definition will not exceed 4 hours.
25 degrees Celsius in the test environment, select the Everest software system is fully baked-in test, the test 15 minutes with UNI-T UT71E intelligent digital multimeter high-load power consumption of the products tested, and used within 30 minutes infrared detection Wenyi inspection body surface maximum temperature of more than one location.
Aspire 4252 in appearance, performance benchmarking and win the game, and practical application in the configuration on the two tied in a life lost on heating power.

In appearance, Aspire 4252 in six color options to the user with a variety of personalization options, the overall appearance of the more stylish slim; and Aspire 4349 is even more simple, more introverted. Although the Aspire 4349 has a USB3.0 interface, additional, but only this one is not a sufficient reason for users to choose it, but the appearance is a more emotional element, of course, everyone in the pursuit of so-called personality and not at the same time, low-key Aspire 4349 users may be able to touch the inner desire for a low profile.
Power consumption and heat in the life, the results quite unexpected, lower full-power (48.9W) and larger capacity battery (56Wh) Acer Aspire 4252g in the endurance test items actually behind on Acer Aspire 4349 more than one hour I am afraid that can only be attributed to nVidia OPTIMUS automatically switching dual-graphics technology, though it sometimes does not Emmanuel, but in most cases still can keep working. Heat in two difference is not large, C 32, 33 degrees of the average surface temperature will not have significant discomfort, more than 50 degrees under full load conditions the outlet temperature is not too high, it can be said of these two laptops cooling is very good.
Seemingly Aspire 4252 won three wins two Ping-negative, but in fact the difference between Aspire 4349 and it did not have much, or even better than 4% of the two products the difference ($ 200) but also smaller. So, what the user how to pick it?
Performance, Aspire 4252 both in the benchmark or in the actual game performance, both wins, but lead is not great, can only say that "small victory", taking into account all the tests on the two laptops are in the game 30 or more smooth performance, so if you do not mind a bit of the frame difference, Aspire 4349 can also be used to smooth the game needs.
Select the Aspire 4349 reason: If you look much, but the demand for audio and video entertainment a little more, then the Aspire 4349 may be more suitable for you, after all, SNB Core processor comes with the video card for a special video design not only adds a dedicated video decoding, encoding media processor also has a project called Quick Sync Video (high-speed video synchronization) function can greatly enhance the speed of video transcoding, while shielding the Core Graphics Acer Aspire 4252 has clearly lost the advantage, while adding the USB3.0 also allows users to more quickly transfer large volumes of high-definition audio and video data.

Select the Aspire 4252 reason: If most of your time to play games, and look great on the laptop requirement, is like the personality of young people to show themselves, then the Aspire 4252 is clearly more suitable for you, there is no "occasional failures" of OPTIMUS automatic switching dual-graphics technology, allows you to focus more on the game itself.
