At present, all of the HD 4000 series graphics cards are 55nm core technology to support DX10.1 and OpenGL 2.0, integrated hardware decoding engine UVD2 and integrated 7.1-channel HDMI module, support the DisplayPort output, support for PowerPlay, PowerXpress, Swithable Graphics and a series of energy saving technology, but the most low-end Mobility Radeon HD 4300 series no Avivo HD technology in the DVD Upscaling and dynamic contrast.

Graphics test: AMD launched Radeon HD 4000 mobile GPU series includes ATI Mobility Radeon HD 4800/4600/4500/4300 several series, won the high-end and low-end, as ATI’s is entry-level graphics card, 3Dmark06 test results from the point of view, good performance in 1024 × 768 resolution performance under the 3268 balance of the total score for the online game World of Warcraft and other large online games easy to run.

HD4570 graphics card with a 55nm process, the number of 242 million transistors, compared to the number of

HD 3470 181 million transistors, the new graphics core area has improved. Another significant upgrade is the Shaders number, the number of new HD4570 Shaders reached 80 (V4.1), while the HD 3470 is only 40, graphics core frequency, the use of the HD4570 Acer AS4540G frequency reached 680MHz, and uses the DDR3 memory, a capacity of 512MB, through 3Dmark 06 test results can still see the graphics performance, the last chapter of the game tests also illustrates this point, it is no problem to cope with the mainstream network and stand-alone game.

With AMD VISION technology and high-definition playback optimize performance, Acer Aspire 4540G plays 1902x1080p high definition movies perfectly, making VISION technology lifelike image clarity.

In the high-definition playback tests, we selected the H.264 format high-definition video, “Fast and Furious” and “Transformers 2.” Unzip the movie is playing hard to open CPU occupancy rate remained at around 5-9 per cent, the screen flows, AMD Mobility Radeon HD4570 graphics card, which is based on its performance is better than the mainstream of today’s low-end alone is significant, and would like to When we first Geforce G105M also praised the performance, this time there have been mountain mountain high, competition can always give us a better product.

Summary:
On the whole, the performance of Acer AS4540G still very good, dual core and has a unique hardware configuration was a very good performance, it can comfortable competence for business users everyday office application. Acer Aspire 4540G brings a strong performance and extends the entertainment experience.
