Another point to note is the common name used by Intel HD Graphics 4000 graphics chip to integrate only in the mobile processor third-generation Core i. But the real tests by showing graphics processing power of each chip in the line are different.

Specifically, the tests 3DMark 11 Performance configurations, the Core i3-3217U processor in the tested configuration was 510 581 Graphic and the overall performance of the Core i7-3517U and Graphic reach 557 points 647 points overall performance (higher by 9-10%).

Similar to the Heaven Benchmark, graphical test 3DMark 11 but similar to emphasize technology tessellation in DirectX 11 graphics library, test configuration at 21 frames / sec and 539 points in 720p HD resolution, set average up graphics.

With the game Street Fighter IV, the test configuration at 8,189 points and 39.6 frames / second at a resolution of WXGA (1,366 x 768 pixels) with default graphics settings. This also shows the power of graphics processing HD Graphics 4000 can reach the threshold of 30 frames second (fps) in a game of light at a resolution of 1,366 x 768 pixels with low graphics settings.

The speed of data access

The traditional equipment of a hard drive (HDD) partially affects the overall system performance. Specifically through ATTO Disk Benchmark test shows the speed of data access most of the system partition is 82 MB / s (write) and 115.7 MB / s (read) or to measure the speed PCMark 05 launch application (emulator) is only 5.4 MB / second, scanning at 120.7 MB / sec. Time to complete the Windows 8 boot process takes about 12 seconds from pressing the power button until the moment when the Modern UI interface to enable the "Turn on fast boot".

Check the speed of copy data via USB 3.0 with 5 GB data sample of 720p video, audio formats *. Wma and the installation source (source) applications, 5421 Touch only takes about 61 seconds to complete 5 GB of copying data from flash drive 3.0 model to the Documents folder and back again, took 102 seconds to copy from the Documents folder to a flash drive.


MobileMark 2007 is one of the top criteria used to evaluate the laptop battery life.

MobileMark 2007 is one of the top criteria used to evaluate the laptop battery life.

What is more impressive is the battery test results of Dell Inspiron 14R 5421 Touch. According to the manufacturer, said Touch 14R laptop equipped with high-capacity 6-cell battery (5640mAh) and features intelligent battery management Battery life should be around 6 hours continuously. This is entirely consistent with the actual test results when playing 720p movies, maximum screen brightness (100%) of the battery life at 6 hours 12 minutes and 11 hours to reach 30 minutes in the MobileMark 2007 Productivity test, the highest in the laptop model number turns each test.

Heat dissipation capability

Besides allowing the performance evaluation, digitized and recorded heat dissipation capability of the machine in environments is with average temperature around 26 degrees C. It works smoothly running office applications, light gaming as entertainment or Radiant Defense Fish with Attitude. In graphics processing tasks and game Alien vs 3DMark 11 Predator, a cooling system is operating fairly smoothly and efficiently when the processor temperature and the highest graphics card respectively 68 and 71 degrees C.
