Performance
The experiment with different hardware
configurations is equipped with low-voltage processor Intel Core i3-3217U (1.8
GHz, 3 MB smart cache, TDP 17 W), integrated graphics HD Graphics 4000, 4 GB
RAM DDR3 1600 bus MHz and a 500GB hard drive.

7 Results
Test results show that the overall
performance of the Dell Inspiron 14R Touch 5421 is only average. However, if
additional consideration other factors such as capacitive touch screen
multi-point, the Windows 8 operating system license and especially battery life
no less high-end ultrabook models, the Touch 5421 is still one attractive
option, suitable for both the learning needs of students, home users and
students and office work.

3DMark 11: Graphics, Performance configuration.
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.
Capcom's
Street Fighter IV is no stranger to many gamers.
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".
Copying
Speed USB 3.0 data, operating system Windows 8
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.
Battery
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.
Advantages
·
Good touchscreen, precise manipulations
·
Impressive battery life
·
Good heatsink
Disadvantages
·
Average overall performance
·
Average display image quality
Overview
·
Design harmony between the performance criteria,
the need to use and portability
·
Although not as powerful hardware configuration
of the graphics processing capabilities, but the Inspiron 14R 5421 Touch
"score" with capacitive touch screen and battery life are no less than
any other high-end ultrabooks.
