Performance
Tested with different hardware
configurations equipped with standard voltage processor from Intel Core
i5-3230M (1.8 GHz, 3 MB L3 cache, 35W TPD), discrete graphics NVIDIA GeForce GT
635M graphics with memory (VRAM ) 2GB, 4GB RAM DDR3 1.600MHz bus with hard
drive (HDD) 500 GB SATA 3 Gb/sec.

Results
in the PCMark 7
The results below showed the overall
performance of the new Lenovo IdeaPad model is quite good, the powerful
midrange GeForce GT 635M Z400 graphics helps meet the learning, working and
entertaining gaming needs, and of course, remains in a certain extent because
of the limitations of mobile graphics chips.

Results
in Heaven Benchmark 3.0, 720p HD resolution, average graphics settings
In 3DMark 11 with Performance test
configurations, the Z400 reached 954 points in Graphic and 1,071 points for overall
performance. With Heaven Benchmark, a graphics test that is similar to 3DMark
11 and emphasizes tessellation technology in DirectX 11 graphics library, the test
configuration attained 21.4 frames/sec and 540 points in 720p HD resolution, which
set average graphics.

A
"heavy" game test for laptop graphics
With the heavy game Alien vs. Predator
(DirectX 11), the 1.366x768 pixel resolution (WXGA) with the lowest graphics
settings (low quality, and 0xAF 0xAA), the Z400’s frame processing speed in the
game is respectively 30.7 fps (frames/sec) and decreased to 25.8 fps when pushing
the settings to the average graphics (medium quality, 0xAA and 4xAF).
The speed of data access
The tradition of a hard drive (HDD)
partially affects the overall system performance. Specifically the ATTO Disk
Benchmark test showed the highest speed of data access of the system partition
is 90.1 MB/s (write) and 107.1 MB/s (read) or to measure the speed with PCMark
05 application (through the simulator) is only at 5.5 MB/second, scanning virus
at 119.2 MB/sec. Time to complete the Windows 8 boot process takes about 12
seconds from pressing the power button until entering the Modern UI interface when
enabling the "Turn on fast boot".

The
speed of copying data via USB 3.0 port, Windows 8 operating system
In a test to check the speed of copying
data with 5 GB data sample of 720p videos via USB 3.0, wma. format music and sources,
the Z400 only took about 62 seconds to complete the copy of 5 GB of data from the
memory pen 3.0 to the Documents folder and conversely, it took 93 seconds to
copy from the Documents folder to the memory pen.
Battery
![The MobileMark 2007 is one of the top criteria used to evaluate the laptop battery life.](http://programming4.us/image/062013/6/11203187.jpg)
The
MobileMark 2007 is one of the top criteria used to evaluate the laptop battery
life.
Regarding battery life recognized by
MobileMark 2007, the device’s configurations at High Performance mode and
screen brightness at 40% (same as switching to battery mode), the Z400 lasted 6
hours 57 minutes 4 hours 46 minutes in the Productivity test.
Similar when playing movies and photos, as
well as in the High Performance mode and maximum screen brightness (100%), this
ultrabook’s battery life lasted approximately 3 hours of continuous showing,
about 35% higher than laptops with 15.6-inch screen in the same test. This is
completely normal because the size and screen brightness are factors that
significantly affect battery life.
Heat dissipation capability
![The temperature was recorded through the HWMonitor and GPU-z utilities, the test environment was at 26 C degrees.](http://programming4.us/image/062013/6/11204202.jpg)
The
temperature was recorded through the HWMonitor and GPU-z utilities, the test
environment was at 26 C degrees.
Beside the performance tests above, we
recorded heat dissipation capability of the device in environments with average
temperature at around 26oC degrees. It works smoothly running office
applications as well as in the graphics processing tasks or heavy games, but
the heatsink is not really effective when the highest temperature of the
processor and graphics card in 3DMark 11 test was respectively 73 and 79 C degrees.
Advantages
·
Strong build, high reliability
·
Unique keyboard with soft keys, good bouncing
·
Good overall performance and graphics
·
OneKey Recovery feature helps restoring the
system simple and fast
Disadvantages
·
The heatsink does not function very effectively.
Overview
·
It is not only an upgrade with the more powerful
specifications, the Z400 also has many fresh colors, which is suitable for
dynamic young people to show their personal expression.
·
In addition, the Z400 has a higher mobility due
to its 25% slimmer design compared with other IdeaPads from the same series.
·
However, the heatsink is not really effective in
graphics tasks or heavy games.
