Acer 4741G hardware High performance and powerful new upgrade

From the exterior view Acer Aspire 4741G does not have any change, but the core hardware configuration point of view, this really is a Acer 4741G upgraded to new models, the resulting overall performance is definitely another shock you. Start talking about the processor, the Acer 4741G equipped with a new Intel Core i5-480M processor, compared to the Intel Core i5-460M processor, Intel Core i5-480M of the frequency is increased to 2.66GHz. The graphics card is not yet configured launch of the NV 500M series graphics - NVIDIA GeForce GT540M, this new card is scheduled for mid-level, with 1GB memory.

Of course, as Intel's new 32nm Arrandale mobile processor, the Turbo on the Intel Core i5-480M than the Intel Core i5-460M processor high. This means have the same 35W power consumption, 3MB 3 cache Intel Core i5-480M has a more powerful processor performance. CINEBENCH R10 to get through the test results can be seen that the three, Intel Core i5-480M owned by Turbo Boost Technology can obviously bring significant performance gains.

Performance testing to meet the mainstream home entertainment applications

We use a series of test software to determine the actual performance of this Aspire 4741G, installed in the test we English Microsoft Windows 7 Ultimate Version 6.1.7600 version of the operating system to be tested. Test content will include CINEBENCH R10, Mobilemark2007, PCMark Vantange other variety of test software.

Overall performance at the beginning of the test, we first carried out for the Aspire 4741G processor performance test, the test in this section, we mainly use the software to CINEBENCH R10 for a simple, intuitive test. CINEBENCH R10 use of film and television industry, software development, Cinema 4D special effects engine, you can test the CPU and graphics 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 firstthe second run all the processor cores and threads. The second test is for the OpenGL graphics performance.

CINEBENCH R10 Test Results

From the final test results, the Core i5 480M processor single-core rendering test score of 3131 points, while some multi-core rendering test results was 7142 points, and had previously been a large number of applications compared to Core i5 450M processor,480M single-and multi-core rendering performance in the range of 3% and 7%. The GT 540M for OpenGL

Part in the machine performance testing, we mainly use the PCMark Vantange software testing, PCMark Vantage is Futuremark released a new generation of PCMark benchmarking software to measure all types of PC's overall performance. Compared to the previous version of PCMark05, PCMark Vantage with the overall structure of the more obvious changes from the previous several subsystems according to PC gradually divided into sub-items according to use, closer to the user's actual use, but also more focused onthe user's reference value larger. It canceled the original processor and graphics sub-items, retained the overall score and HDD (hard disk) two children, while increasing the Memories (memories), TV and Movie (video), Gaming (games), Music (Music ), Communication (communication) and Productivity (productivity) of several new projects.More suitable for measuring PC performance for home entertainment.

3DMark Vantage test results

Test results from the above point of view, the use of GT 540M graphics card, so this in this part of the Aspire 4741G is still quite good test scores, 12581 points and 15314 points composite score GPU test scores indicate that this product can to meet part of the mainstream gaming applications, while we also see that the Core i5 480M processor performance is also very good, 8193 hours of test results indicates that the user can rely on high performance processors to easily respond to the needs of some mainstream 3D applications .

We also used TOPCON's BM-7 spectral colorimeter for the Aspire 4741G's screen test, the test we have chosen the right of the screen brightness, contrast and color saturation test. Brightness of the test, we make full-screen white display image, the center of the screen test, contrast test also used the same test method. We measure the color saturation monitor to show the red (R), green (G), blue (B), then the color value of the test center of the screen. In the CIE color space R, G, B three points around the triangle area is the display area can display all the color, the size of the region defined RGB and NTSC 1953 color gamut area ratio is the color saturation. The sRGB standard color range defined by about 71% NTSC, which is currently the general level of CRT monitors that can be achieved.

Acer Aspire 4741G Battery life, the actual power consumption and heat control test

We mainly use the Mobile Mark2007 software to simulate the daily office and multimedia production and other major applications to conduct a comprehensive assessment of endurance capacity. MobileMark 2007 is a notebook based on real-world battery life and performance evaluation software. It supports 64bit/32bit versions of Windows Vista / XP (Professional / Home). It has three test modes: Productivity module, DVD module, Reader module, respectively, will be called Adobe AcrobatReader 7.0, Adobe Illustrator CS2, Adobe Photoshop CS2, Apple Quicktime 7.1, Intervideo WinDVD 8, Macromedia Flash 8, Microsoft Office 2003 Pro, Microsoft Project 2003, Winzip 10.0.

In the notebook, we will run Productivity module and DVD module test, and record their performance scores and life. In the Internet, we will run the Reader module and the DVD module. In this product we have tested the high-intensity office and DVD player two areas, office areas in which high-intensity routine office simulation run the user access to various software, and the system will be mixed, ranging from intermittent time to the maximum extent simulate user operating environment. The DVD part of the test is simulated home environment, the more extreme DVD playback test, we test the DVD module used in the virtual drive, computer hard drives to read data from the test, so the use of drive test data and there will be some deviation, However, we believe that such a test method but better than the use DVD drive to read closer to the user's habits, after all, most used in the playback of video or read more data from the hard disk.

We tested the OPTIMUS technology under Acer Aspire 4741 battery life, this is a 48Wh 4400mAh capacity Acer Aspire 5552G battery, alone in the ordinary 14-inch display notebook, such a battery is only 180 minutes to bring life, and Acer Aspire 4741G, we see that the time to break through to 236 minutes (full load condition), a full four hours of battery life, absolutely guarantee you a morning with the demand.

In the test, we close the screensaver, sleep, and set the battery and the system are the highest performance mode, the test session in the office environment, 4741G of this battery charge 0% in the remaining conditions to provide users with 245 minutes of battery life , and in the DVD player environment, compared with 197 minutes of battery life. Taking into account this product uses a high frequency and high-performance graphics processor, and the need to frequently test the hard disk read and write operations, so that such results can still be acceptable for most users, the user further if life demand, then, can the built-in notebook power management mode is set to carry out the program, so as to achieve the purpose of further enhancing life.

Actual power consumption test

We also tested the actual power consumption of this product, we have tested this product in the three state power consumption. We use UNI-T UT71E intelligent digital multimeter for testing equipment, 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, loaded processor, disk work at maximum throughput (non-charge state), the power situation.

In the three test conditions, Aspire 4741G power are 0.5W, 10.8W and 49.9W, this test data and market some of the similarly configured notebooks compared to the power consumption in standby mode in a same level, while under high-load power consumption targets will have to run slightly higher than similar products. This test data indicate that this product uses a high-performance parts, so its power consumption is also to be seen, users enjoy high-performance, while bound to bear the resulting high power consumption.

Heat test

In this test session, we adopted the FLUKE Ti25 thermal imaging equipment on this product heat conducted a test to test the laptop main measure C, bottom heat and the temperature of the mouth. In tests, we use the EVEREST software, select the System Stability Test, check all items, 15 minutes after the test, we measure the indoor temperature, the test data to make the reader a more intuitive understanding.

Heat vents

Position in the vents, the highest measured temperature is 55 degrees Celsius. From the temperature of the test results, this notebook is relatively normal for heat control, high-intensity users in a long time when you feel comfortable with, who often need to text, graphics, etc. dealing with business users, this product High heat will make them feel inconvenient in use, and for the 3D gaming applications-oriented users, the game takes a long time because of high work load, it is difficult to get a good use of user comfort.

Testing Center view - is the highlight of the performance alone was

Positioning at the end user of the NVIDIA GT 540M independence was joined in this new configuration of the Aspire 4741G lot of extra points, while the Core i5 480M processor was running some of the users of this product provides a high load application infrastructure , for some budget shortfalls while users who want to play the game, so the temptation is not small, after all, the $ 6,000 level of the product, so there is quite a rare mix, or if you apply for 3D games program has certain requirements, we recommend that you consider this Aspire 4741G, after all, the brand has an advantage, good cost performance. And this product also supports both low-power high-performance graphics processing and long battery life of Optimus technology. From the nature point of view, Optimus Technology and Intel introduced the built-in graphics processor unit coincide, Optimus technology can take advantage of the built-in integrated graphics processor, but can also enable manufacturers to i ntroduce more distinctive notebook products. The simplicity and intelligence on this point of view, the user can go before running the program does not have to manually switch the graphics mode, the program will help users to run programs based on the current load level to automatically switch the video card, so that you can simultaneously achieve both enjoy a high-performance graphics card brings superior graphics processing power, but can also enjoy the integrated graphics to bring long life.

Acer Aspire 4741G notebook

The comprehensive test performance of this product, we believe that this product is suitable for those who have a certain appearance of the product requirements, while in the application to run everyday office software, text applications, 3D games and medium-load-based user Entertainment In addition this product is quite suitable for those who demand a product with higher performance, but also requires control of the purchase price within a certain range of users.
