▲ Core i5 24 10M integrated Acer4750G comprehensive evaluation.
As a notebook product for positioning low-end business applications, the performance of the processor largely determines its comprehensive performance. Because the integrated graphics card brought by Core i5 24 10M has the performance of low-end entry-level display, although the high-end discrete graphics card can make the product's performance in graphics processing smoother, considering its high cost and high power consumption, it is obvious that the integrated display notebook with the new Core I series processor is more suitable for this positioning. Below, we will comprehensively measure the comprehensive performance of this Acer 4750 through typical simulation application test, game test and software test in the office environment.

This 4750 continues the traditional style of Aspire series in the body shape, and its top cover is treated with metal stamping grid effect, which can effectively avoid the problem that the surface similar to piano paint is easily contaminated with fingerprints. The machine adopts the design mode of smooth transition of corners, which also increases the firmness of the fuselage. During the test, we put our hands on its top cover to squeeze it, and there was no obvious deformation during the test, which showed that its screen protection ability was good.
▲ The A side of the fuselage is treated with metal stamping grid effect.
The frame of the B-side screen of the machine is treated with a paint effect similar to that of a piano, and the camera is still set in the center of the frame on the screen. The frame treated with piano paint effect is not only beautiful, but also easy to be contaminated with fingerprints. For machines with mirror screen, this treatment process may cause total reflection in strong light environment, which brings inconvenience to users.

As can be seen from the figure, this ASUS A43S adopts Acer's usual duckweed design in the keyboard part, and the panel part around the keyboard adopts stamping effect, and the light gray palm rest and keyboard frame part form obvious contrast with the keyboard area visually. The touch panel of the machine adopts integrated design, which can effectively prevent dust and foreign objects from entering, and the resistance of the left and right buttons is moderate, which makes it feel better in practical experience.
▲ There is obvious contrast in color between the keyboard area and the surrounding area.
▲ The touchpad is integrated.
This 4750 provides users with two USB2.0 interfaces, 1 USB3.0 interface, 1 HDMI interface, 1 RJ-45 and 1 audio and microphone combined interfaces and an all-in-one card reader, which can meet the daily needs of most users. In terms of layout, because the number of interfaces is less, the layout is more reasonable, and the distance between two independent USB interfaces is longer, which will not affect the user to insert two large-size USB devices at the same time.
▲ Interface layout on both sides of the fuselage
Acer 4750G uses Intel Core i5 24 10M processor as the core hardware, which adopts the latest 32nm technology. It is a native dual-core 32nm processor product released by Intel at the beginning of 20 1 1, with a main frequency of 2. 3GHz, supports Turbo Boost technology, the processor's third-level cache is 3MB, the processor is dual-core, supports HT Hyper-threading technology, has dual-core and four-thread processing capability, and the thermal design power consumption is TDP 35 W. ..

In terms of chipset, HM65 has replaced HM55 as a close partner of the new Core processor. Like previous mobile chipsets based on desktop chipsets, HM65 chipset originated from H65 chipset on desktop. HM65 also uses single-chip architecture and memory.
The control unit (IMC) is integrated in the processor, so there is no MCH (Memory Controller Hub) commonly known as the North Bridge chip. Only one platform control unit, PCH (Platform Controller Hub), undertakes the functions provided by the previous PCI Express controller and ICH (Input/Output Controller Hub), which is usually called the south bridge chip. HM65 can support up to six SATA 6Gbps interfaces (including eSATA), eight PCI-E 2.0 x 1 interfaces, 14 USB 2.0 interfaces, Hanksville GbE MAC Gigabit Ethernet controller, matrix storage technology, high-definition audio and high-definition audio, and management engine ignition firmware technology.

In the storage accessories section, this Acer 4750G uses a combination of 2GB DDR3 1333 memory and 500GB 5400 rpm hard disk. 500GB of storage capacity is enough for most users, while 2GB of memory is relatively small. For users who have the ability to use a 64-bit system, we suggest that they add a piece of memory themselves.
▲ The bottom of the fuselage is not easy to disassemble and easy to upgrade.
Judging from the evaluation results of WIN7' s own system, the final score of this 4750 is 5.5, which is the lowest desktop graphics performance in all sub-projects, but considering that the machine is not equipped with a separate graphics card, this result is also expected. Among other sub-items, the score of processor sub-item 6.9 is the highest score of a single item, while the score of game graphics sub-item 6. 1 shows that the machine can carry some low-end 3D games. Judging from the scores of memory and hard disk, its memory score is relatively low, and we also suggest that capable users can consider adding another memory for it.
▲Windows 7 index test
In addition to using the index test that comes with Windows 7, we also selected three professional performance evaluation software with high coverage and widely recognized by users to test this product. The test results of 3DMARK, PCMARK and SYSMARK can help us to understand the performance of this product in several applications more intuitively.
▲3DMARK test scores
▲PCMARK test scores
▲ Saymak test scores
In the previous test, although we got intuitive scores through the test software, for many readers, we really can't have an intuitive feeling about the performance represented by these scores. In view of this situation, in order to make more people feel the performance of this product more intuitively, we use it in some typical applications, including file operation, high-definition video playback, image compression and other operations, so as to further evaluate its comprehensive performance in daily applications.

World of Warcraft, Need for Speed 14, Call of Duty 7 measured
World of Warcraft flight test
World of Warcraft is a massively multiplayer online role-playing game (MMORPG) produced by the famous game company Blizzard Entertainment. It was publicly tested in North America in mid-2004. In view of the fact that World of Warcraft is the most famous online game in Chinese mainland, we also chose this game for testing in the test, and we adopted a point-to-point flight test method.
▲ World of Warcraft test video
In the flight test of World of Warcraft, because the scene changes rapidly, we see that its frame rate is basically maintained between 23 and 34 frames, with an average frame rate of about 26 frames. Although the frame rate of this 4750 is lower than 30 frames in a complex scene environment, it may have little effect on the operating feel. Because we used excellent picture quality in the test, if we turn down the picture effect, we will get a smoother operation experience.
Speed 14 test is required.
Need for Speed: Chasing is EA's latest racing game, developed by Criterion Games Studio, and is also a new generation of heat tracing series. This game returns to the police wanted mode, allowing players to play online all over the world, and will return to expensive sports cars again. We still use 1280X720 pixel resolution in this game test.
▲ Need for Speed 14 test video
Judging from the above test of Need for Speed 14, the frame rate of this 4750 has been stable at around 15 frames. Running this game with such a result will cause obvious frame loss, and at the same time, because we used high-quality settings in the test, we can still get better game effects without high requirements on its image quality.
Call of duty 7 test
Call of Duty: Black Ops is the seventh part of the famous FPS game Call of Duty series produced by Activision, which was produced and developed by Treyarch Studio. /kloc-0 was released on October 9th, 20 10, 165438. The platform is PC, Xbox360, PS3 and Wii. The story took place in the Vietnam War and some areas during the Cold War, such as the Arctic and Cuba. Players will play members of mysterious organizations and perform assassination and ulterior tasks. Besides, Sam was invited to watch the game? Worthington, Gary? Odeman ed. Famous Hollywood movie stars such as Harris voice the game characters. In the test, we installed the full version of the game with a resolution of 1280X720 pixels. The picture quality is set to medium, and anti-aliasing is turned off.
▲ Call of Duty 7 test video
Call of Duty 7, as a game with high hardware requirements, represents the application requirements of large-scale 3D games at present, and it is usually easier for us to distinguish what level of game performance a notebook can achieve. From the above test video, we can see that only about 10 frame was achieved when testing with this machine, which shows that it is very difficult to run such 3D games with high load using integrated graphics cards.
Street fighter 4 measured
The PC version of Street Fighter IV is a completely transplanted version of the home computer version, which will correspond to the game functions of Windows Live and support online battles, in-game SMS communication and instant voice chat. In addition to supporting high-resolution screen output, the PC version also provides players with the function of selecting screen rendering style, except for the PC version? Ordinary? Beyond the mode, what else? Watercolor? 、? Poster? And then what? Grey ink? These three additional rendering styles. Players can adjust the display effect according to their own preferences in the game setting options. In the test, we used Capcom official PC performance test software to test, and we chose 1280X720 pixel resolution, and the rest settings used the default settings of the game.
▲ Street Fighter 4 game test results
Judging from the final test results, the machine has no problem in dealing with such low-load games. The average frame rate of 29.6FPS shows that the game process is smooth and will not affect the operation feel, indicating that the configuration of the machine can meet the needs of low-load games.
Measured by resident evil 5.
Resident evil 5 is the fifth game of this game. This time, the stage of "resident evil 5" is set in a small African country (the story is pure fiction), which is located in an active volcanic zone, spanning Eritrea, Ethiopia and Kenya. At the beginning of the game, the local residents were not infected, but with the volcanic activity,
The outbreak of the virus gradually spread, turning local residents into zombie-like killing creatures. In the test, we used Capcom official PC performance test software to test, and we used 1280X720 pixel resolution mode to test.
▲ resident evil 5 test results
As can be seen from the screenshot of the above test results, when the game runs at the common resolution of 1280 x 720 and the picture effect is set to medium, this 4750 can provide users with an average frame rate of 26FPS. At this frame rate, the screen can basically be smooth during the game, and the game can still be played smoothly despite the poor operation feel.
Battery life, actual power consumption and calorific value test
battery life
We mainly use Mobile Mark2007 software to simulate daily office, multimedia production and other major applications to comprehensively evaluate endurance. MobileMark 2007 is a notebook battery life and performance evaluation software based on real applications. Support 64-bit /32-bit versions of Windows Vista/XP (Professional Edition/Home Edition). It has three test modes: productivity module, DVD module, reader module, Will call 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。
▲11.1v/4400mah/48wh battery is standard.
▲ Screenshot of ▲MobileMark 2007 test results.
In the test, we turned off the screen saver and hibernation, and set the battery and system to the highest performance mode as the test basis. As can be seen from the above figure, the performance of this Acer 4750 notebook in the test can provide users with 399 minutes of battery life, which can meet the mobile office needs of most people. In addition, considering the high voltage in the test, there will be no continuous high-load application in practical application, and users can control it through effective power management measures. We have reason to believe that its battery life in practical application should be better.
Actual power consumption test
We also tested the actual power consumption of this product, and we tested the power consumption of this product in three states. We use UNI-T UT7 1E intelligent digital multimeter as test equipment to measure the connected power supply respectively.
However, the power consumption is not in the boot state (non-charging state), the system is fully started, and there is no action for 5 minutes, but it is not dormant (non-charging state). The system is fully started, the processor is fully loaded, and the disk works at the maximum throughput (non-charging state).
Under three test conditions, the power consumption of this 4750 is 0.3W, 13.8W and 44.6W respectively. This test data is slightly lower than that of notebooks equipped with discrete graphics cards, indicating that users need to pay lower electricity bills when using this machine.
Caloric value test
In this test, we used Fluke's Ti25 thermal imaging instrument to test the calorific value of this product. The test mainly measures the temperature of the C surface, bottom surface and radiator of the notebook. EVEREST software was used in the test, the system stability test was selected, and all items were checked. 15 minutes later. At the same time, the indoor temperature is measured, so that readers can have a more intuitive understanding of the test data.
▲ Distribution of cooling holes at the bottom of the fuselage
We tested the temperature at five points around the test platform. The temperatures at the five points are 25.7, 25.7, 25.6, 25.2 and 25.5 degrees Celsius, with an average of 25.5 degrees Celsius.
▲ Thermal imaging of 4750 keyboard surface
▲4750 bottom thermal imaging map
▲4750 cooling outlet temperature
As can be seen from the above test chart, the temperature of the keyboard surface and bottom surface of the notebook has exceeded the normal body temperature of the human body, but because the temperature difference is not large and the heating area is relatively large, it will not give people the feeling that the temperature is too high at a certain point, but will feel warmer all over, and it will not make people feel particularly uncomfortable when using it.
Under the background of fierce competition in notebook sales, the price of a product greatly affects the purchase tendency of users. This Acer 4750 has successfully maintained the price at the early 4K while ensuring the hardware factors such as solid fuselage and overall performance, which is believed to be very attractive to users who value the price. As far as the overall hardware configuration of the machine is concerned, we suggest that capable users increase 1 block of 2GB of memory for it to obtain better overall performance.
Earlier, we mentioned that the comprehensive display performance of Core i5 24 10M has basically reached the level of entry-level display, and it is true from the software test results. 776 1' s 3D Mark Vantage test GPU score is better than the familiar previous generation entry-level monitor. From the practical application point of view, this product can perform well in daily office, audio and video playback, low-end 3D games, etc. However, if users want to run some medium-sized 3D games, they need to sacrifice the image quality of the games to ensure a certain fluency.
