Time to move on to March, gradually as the SNB new platform products listed, dealers are scrambling to clean up inventory notebook products last year. I'm using the next-generation processor notebook must upgrade in performance, but since the launch of product performance, overall profit is full of gimmicks and other factors, the price is also not very approachable, which also left many consumers with valued performance. For such users, in fact, in this particular point in time, choose a cheap enough price's old product would be a wise choice. ACER LAPTOP BATTERIES.
Acer 4745G as last year of best selling models still for consumer prepared has multiple match of products, today we to for members brings evaluation of this paragraph products of core parts part by cool duo i3 350M processor and HD 5,650 independent graphics by composition, although its processing performance does not is high-end, but tie this paragraph graphics still can smooth run most of 3D game, then plus the machine now price only 4 k more, can said is a paragraph has higher price/performance of notebook.
This appearance is still that we are familiar with the style of 4745G, which is one of the Acer my usage of the classic mould, its a top cover part of the use of a ripple in the film printing, looks beautiful but vulnerable to leave fingerprints. We had a plane in to actual means test, and there is no clear settlement, prove the top cover of the product can provide excellent protection for the screen. ACER laptop battery
Side b screen borders part of the 4745G class to handle piano paint effects, the camera still central location of the border is set on the screen, the border Although aesthetically pleasing, but easier to tainted fingerprints for use mirror-screen the machine may be in a strong light conditions causing inconvenience to the users.
4745G c is still using the traditional style of the Aspire, around the keyboard Panel using the same punch as a surface treatment effect, select dark grey color, has a good contrast to the keyboard regional effects, while the overall color and more harmonious. Integrated touchpad design, you can avoid foreign bodies out dust, the left and press the key to the resistance is moderate, feel better in actual practice.
On developing interfaces, 4745G provides users with the most commonly used interfaces, including 4 USB 2 interface, 1 HDMI connector, 1 x VGA connector, 1 x RJ45 socket, 1 multi in one card reader and 1 set of headphone/microphone jacks.
This 4745G with the Intel Core i3 350M processor, the processor uses the latest 32nm process manufacturing process and frequency 2.26GHz. Core i3 350M of three-level cache is 3MB, a dual-core processor and supports Hyper-Threading technology HT, with dual-core Quad-Threading capacity, thermal design power TDP 35W.
In terms of chipset, 4745G uses a HM55 chipset, codenamed Ibex Peak-M its development, using a single-chip architecture, memory control unit (IMC) was integrated into the processor, so it is not commonly known as the MCH North bridge chips (Memory Controller Hub), there is only one platform control unit PCH (Platform Controller Hub) burden in the past on a single chip PCI Express controller and commonly known as ICH Southbridge chip (Input/Output Controller Hub) functionality provided by, and compared to the dual-chip architecture, single chip have more advantage in power consumption and heat, whether it is help laptops better heat dissipation is to enhance the life, was a prerequisite for good.
4745G used as a graphics ATi Mobility Radeon HD 5,650 discrete graphics processing unit, the card support DX11, is positioned higher in the ATi Mobility Radeon HD 5,000 series video cards of a product, based on 40nm process technology, with 400 stream processors, 20 texture units, 8 rasterization unit, core frequency is 450-650MHz, the video memory frequency is 800MHz, Floating-point computing power for the 360-520GigaFLOPS. ATI Mobility Radeon HD 5,650, to be completed with 128-bit GDDR3/DDR3 memory, support DX11 UVD2 hardware decoding engine and OpenGL 3.2, integration, support PowerPlay, PowerXpress, Swithable Graphics and a series of energy-saving technology, thermal design power TDP 15-19 Watts.
In testing, we turn off the screensaver, hibernation, and set both the battery and the system for maximum performance mode as a basis for testing, you can see from the above picture 4745G this Acer battery for 210 minutes of battery life, this time can only meet moderate Office applications. Due to the high pressure in the test, and in practical applications the user can control power management measures through effective, so in practice should be longer battery life.
From the positioning point of view, the Acer 4745G in the main market for high-end gaming notebooks, HD 5,650 independence dominant in comparison with the other major part can be the most prominent. Tests can be seen from the front, to the machine's performance can provide better support for most mainstream games, due to its 2G DDR3 memory and 320GB 5,400 rpm hard drive performance is relatively low, so in the Office application performance is not prominent.
