Display characteristics
Screen size 15.6"

The display size describes the size of the visible part of the screen of your portable computer across the diagonal in inches. Average portable computers have 15.4" standard or 15.6" wide-screen displays. The ultra compact category portable computers have the display size of about 10,1".

Some portable computers have the option of turning the screen to the angle of 180 degrees and close it with the keyboard – the result is a true tablet computer without a keyboard. These models are sometimes referred to as transformers or tablets - they can be used both as a standard portable computer and as a tablet computer. This option is very handy for reading or, for example, drawing when the keyboard is not required.

Portable computers that are positioned as a replacement of desktop computers sometimes have the screen as big as 17". A bigger monitor is usually required for editing graphics or reviewing big-size tables, etc. However, it has to be considered that a bigger screen means a bigger size and usually also a bigger weight of the computer, besides it can be damaged more easily during opening and closing.

Screen resolution 1920x1080 (Full HD)

The maximum resolution of the display indicates the number of colour points (pixels) on the computer screen. The higher the resolution the better quality (more detailed) image. For example, 1366x768px means that your computer has 1366 points horizontally x 768 points vertically. High resolution provides more information on the screen and this is directly related to the size of the screen. Nowadays even a 12.1 inches screen can have 1024x768 resolution. At the first glance it looks that this resolution is too high for this size of the screen, however, high resolution provides more comfort.

WVGA (800x480) is characteristic for old portable computers and mini tablet computers of the new generation. WSVGA – ultra mobile portable computers with the display of 10.1’’ (the resolution of 1024x600 can be seen more often).

WXGA (1280x800) – this resolution is mainly characteristic of 12.1’’, 13.3’’, 14.1’’ screen with the relation of sides of 16:9.

HD 1366x768 and 1600x900 is a widespread resolution for the budget and middle class portable computers.

Full HD (1920x1200) resolution combined with high capacity video cards (NVidia Quadro FX vai ATI FireGL) is intended for the professional level 3D modelling work.

WUXGA (1920x1200) – ultra extended graphical arrangement (screen16:10) is intended for watching HD TV.

Attention has to be paid also to the contrast and brightness of the screen. The screen must have the maximum brightness for using the portable computer even in very bright lighting conditions.

Basic information
Color : Silver
Processor parameters
CPU TurboBoost frequency 5.00 GHz
The ability of the CPU to increase the performance (the clock frequency) of one or several cores on the account of the stand-by of other cores. This function is switched on only when the computer needs an additional capacity "push".
Processor Threads 12 Threads

HyperThreading is the ability of the computer CPU to process several data flows in each core. For the two core CPU the HyperThreading is 4 and it means that certain tasks can be handled by this two core CPU at the same quality as the four core CPU.

CPU cache 12 MB

The CPU cache memory is the place where the CPU stores (buffers) the data intended for processing for a short time. The volume of the cache memory is important in determining the high-speed operation of the CPU and, thus, the overall high-speed operation of the computer itself. Bigger volume of cache memory means higher-speed operation.

Random-access memory (RAM)
RAM 16 GB

RAM is a short-term data storage. This component determining the operation speed:

  • allows the CPU of your computer to have fast access to the information that needs to be processed used by the computer application which you have opened;
  • at the moment of opening an application stores it in its microchips, thus the memory capacity determines how many applications can be run by your computer simultaneously and also with how big data volume (pictures, texts, webpages) you can operate at once.

Thanks to the dense placement of chipsets the RAM of a portable computer has the same characteristics as the RAM of desktop computers. TopPC.fi recommends to use 3Gb or higher capacity RAM for general use.

RAM type DDR4

This criterion determines the type of the RAM used by the computer,m and this is useful if you want to buy an additional memory module when you buy the computer or upgrade the existing RAM capacity in future.

The newest type of memory is DDR3. DDR2 represents an older generation accordingly.

RAM type 3200 MHz
The high-speed operation of the RAM as well as the upgrading possibilities are determined by the index - the type of RAM. TopPC.fi recommends to buy a portable computer with DDRIII type RAM.
Maximum RAM upgrade option 16 GB

Maximum RAM is the indicator of the upgrading possibilities of the portable computer determining how many Mb of RAM are supported by * this model of the portable computer.

*The possibilities of upgrading the RAM depend on the number of available free memory slots and on the amount of Mb memory in the basic configuration of the computer.

Hard drive
SSD 1 TB

AnSSD, or Solid State Drive, is a modern storage device that, unlike hard disk drives (HDDs), has no moving parts and stores all information on NAND memory chips. This is why SSDs are much more reliable, as they can withstand shock, vibrations and temperature changes much better. The main advantage is the high data transfer speeds as well as the lowaccess time. Currently, SSDs equipped with a SATA 3 port deliver data transfer speeds of 500 MB/s on average. However, some drives using M.2 or PCI-Express ports have data throughputs

of up to

2000 MB/s.

Ports and equipment
Pieslēgvietas USB Type-A 2.0 1

USB 2.0 is the most popular connection slot for the computer peripheral devices. Thanks to this connection slot it is possible to connect mice, keyboards, webcams, printers, USB flash memories, external HDDs and numerous other devices to the computer. The higher the number of available USB2.0 ports, the better.

Pieslēgvietas USB Type-A 3.0 1

USB 3.0 is the newest and fastest USB standard that allows to connect all the devices of the preceding USB2.0 generation and the new USB3.0 generation.

The true advantage of this connection can be seen when the USB3.0 external HDD or the USB3.0 flash memory is connected to the USB3.0 connector. This speed of operation of this solution can exceed the predecessor USB2.0 standard by several times and even the current speed record holder - FireWire connection.

HDMI Ir

HDMI is the digital image and sound transmission standard that allows to connect a TV set, monitor or projector supporting HDMI to the computer via the HDMI cable.

Cardreader SD

This device allows to copy photos from the memory cards of digital cameras without connecting the camera. All you have to do is to insert the relevant card in the reader and all its content is available in the computer at the very same moment.

There are different types of cards (SD, MMC, xD, MS Pro, etc.), therefore you should verify whether the selected card reader supports the required type of the card.
