With the release of Sandy Bridge, equipped with the new second-generation Core i Series notebook processors will gradually become the mainstream. Second-generation Core i series integrated graphics processor in the chip, not only raise a lot of processor power, has been cast aside by many great integrated graphics performance alone was the trend started to catch up. 2010 popular models Acer 4741G surely we are all familiar with the debut today of the 4741G is the "zoom upgrade" - Acer 5750G. A product that follows the mold before, the main difference is equipped with a second-generation Intel Core i7-2630QM processor, the display of the support of NVIDIA GeForce GT540M graphics card and Intel Core auto-switching.
Second-generation dual-graphics card automatically switches i7 processor
Because this product is basically the same mold with the previous, so we focus on performance testing on this product. Processor, the Acer 5750G uses the Intel Core i7-2630QM, clocked at 2.0GHz, Core frequency up to 2.9GHz. The processor uses the new Sandy Bridge architecture, 32nm manufacturing process, display native integrated GPU core, adding a new video encoding / decoding, support for Turbo 2.0 technology, and has 6MB of L3 cache. Performance than the "older generation" has been greatly improved.
Graphics, the Acer 5750G dual graphics support NVIDIA's OPTIMUS automatically switch technology, performance and endurance in the balance between play an important role. Independence was the use of the NVIDIA GeForce GT540M; set of significant aspects is Intel's next generation of "core graphics" than previous integrated graphics performance improved about twice.
Performance has been said, the most convincing data. Processor test session we used the familiar Cinebench R10 software, this software through a high-precision image rendering to test the processor in single core mode and multi-core performance of the state. The results shown below, this single-core i7-2630QM get 4642 test points, and in the multi-core test got a score of 17030. We take it and the previous generation i7-820QM contrast, can be found by comparing, this multi-core processor computing power is about twice the previous generation product.
To force the processor, graphics card is not weakness. Graphics cards, this Acer 5750G is also more "to the force." Alone was tested in GT540M got a score of 9053, and part of the test set was also obtained 3860 marks. We know that the previous generation high-end graphics performance in the 7800 or so, then this GT540M points compared to 9000 increased by 15 percent. The scores on the generation set was only about 2000 points, a new generation of core reached 3860 points card more visible improvement is very obvious.
261 minutes battery life outstanding overall performance
Aspects of large-size notebook is not the point in life, 15.6-inch Acer 5750G battery specifications for the popular 48Wh, but after testing we found that this product's life time to reach 261 minutes. Results of more than four hours which is very high score in Big Ben.
In fact a very good explanation of this phenomenon, two graphics auto-switching capability in the test played a significant role, while the next-generation platform for power control is withheld.
The whole test, we chose PCmarkVantage and SYSmark 2007 these two software. PCmarkVantage biased in favor of the test machine to complete certain aspects of the SYSmark 2007 is more user-oriented simulation of the real operation. Overall, test scores are more impressive. Although the mechanical hard drive is the mainstream configuration, but with the escalation of the processor and graphics, traditional mechanical hard drives may gradually become the bottleneck of many machines.
Mentioned earlier, the mechanical hard drive, then we take a look at this Acer 5750G hard disk information. 500GB hard disk capacity is sufficient for storage, but the hard disk performance can only be unsatisfactory, compared with the SSD solid state drive, there are still some gaps. Conditions permit users can upgrade the hard drive in order to achieve higher and more balanced performance.
Classic black and gray look good feel the texture pattern
Performance test session came to an end, the following pages we look to the machine and details and other information.
The Acer 5750G is not much the appearance of new areas, continuing the previous generation of mold design, black and gray tones relatively calm, the unique surface texture pattern machine feel good, not slip resistant, but also can effectively avoid the fingerprint residual. A central silver surface is also very eye-catching logo acer letters.
Acer 5750G 15.6-inch wide-screen design, a resolution of 1366 768. Performance acceptable, if higher-resolution display, then I believe will be more delicate. Screen just above the standard for notebook camera, we will not repeat them.
Duckweed keyboard design Dolby certified surround sound
With the appearance of some of the same keyboard, Acer continues duckweed classic design. Although the keys from the right, key surface is relatively large, but the keys feel slightly harder to use, no surface depression treatment, prolonged use of the words may be more tired. Concave relative to some of the palm rest touchpad and matte processing, slide your finger on it more comfortable, more accurate positioning. Integrated buttons and keyboards, push up slightly laborious.
Shell around the palm rest and the use of the same material, surface texture are designed to place the wrist in the above would be more comfortable. As shown, the right palm care cited this Acer 5750G hardware
Acer Aspire 4741 battery parameters and characteristics of the host, left palm was asked a variety of logo, in addition to genuine Windows 7 logo, the new Core i7 and NVIDIA OPTIMUS logo is very eye-catching logo .
Throughout the C surface, giving a very simple sense, in addition to the upper left corner of the power switch button, the machine does not have any shortcuts. With the power button panel with wide parallel is with Dolby advanced audio technology, can produce virtual surround sound speakers. Trial process, the speaker has a certain effect of penetration.
As a result of the ordinary sinking shaft design, the maximum opening angle of the aircraft was only 135 or so, the application does not respond to common problems, if it is placed in special circumstances demand, the opening angle of the slightly nervous.
Equipped with outstanding performance USB3.0 temperature
Interfaces, although not equipped with e-SATA interface, but with a USB3.0 interface, amazing. USB2.0 transfer speed of USB3.0 is eight to 10 times, sending large files like regular users enjoy the blessed. In addition, VGA, HDMI high-definition interface is everything, and fully guarantee the aircraft's external capabilities. You can see, the interface between the display of the interface is relatively reasonable, common headset jack and USB jack are designed in the forward position, user-friendly, and less often or not often plug the cable interface design in the rearward
Acer Aspire 4740G battery position, these details are more intimate.
In addition to both sides of the interface, the left front of the machine arrangementhow-card reader, it is next to several system status indicators. Right place appropriate interface design, light, Acer 5750G performed well in the details.
Finally, we look at the aircraft's weight and heat dissipation. 2.551Kg the whole weight and 3.070 of travel are considered normal weight, portability advantage is not estimated how many users will not have all day to carry such a large machine.
Relatively good heat dissipation. Our high-load operation in the whole two hours after the surface temperature of the test, as follows below. Whether positive or on the back, the highest temperature did not exceed the average human body temperature. This temperature control with outstanding performance, in addition to its good cooling system, the relatively relaxed environment is also very important within one of the reasons.
Summary
Acer 5750G is equipped with the first second-generation Core i Series processor models, I believe will be the first choice for many new users to recover one. Acer 4741G as the older generation of "zoom upgrade", 5750G continues the pattern of appearance of the texture full of texture, black and gray tones appear calm low-key. Overall performance in the i7-2630QM with NVIDIA GeForce GT540M of combinations have been significantly improved, dual graphics cards
Acer Aspire 4771 battery also automatically switch to ensure maximum performance and life balance. Excellent thermal performance will be competition for a lot of weight increase. Of course, the continuation of the classic appearance is good, but if the newer and better mold, I believe will attract more consumers.
