How to choose your laptop 1G memory and 2G video memory

Notebook selection of large memory, not enough to upgrade, the video is not enough to upgrade.

1G memory is basically enough, if the same graphics card, 2G video memory will be better than 1G video memory, but by the core frequency and the number of stream processors, as well as the impact of the memory bit width, pure memory capacity does not cause any intrinsic performance improvement, The following is a brief talk about what the benefits of the larger display are and the relationships between the other parameters.

2GB Single display Notebook if the model of the video card and 1GB of the same notebook, then the advantage lies in the 2GB of the independent graphics card to play the game, the game can be higher resolution, the most obvious role, of course, the resolution of the same situation can be replaced by a higher effect, Remember that when the graphics card to do the screen effect of the image effect of the intensity and resolution is a multiplication of the relationship, the result is equal to the memory can be stored data and graphics core processor data bottleneck.

If the video memory is not enough, the frame number of the screen will be relatively low, and the number of frames is average, there is no fluctuation, the same core computing power of the graphics card is also the effect, but because the graphics card core or processor computing power may be in different frames in the frame number of floating larger, this is what we usually call the game screen card Game screen cards are also divided into many kinds, careful comparison to know which hardware is the performance of the lack of results.

The meaning of memory capacity:

The capacity of the video memory determines the ability to buffer the game data, the main effect is to double open or open 3D online games when the client to ensure that the frame number is not due to the lack of video memory is very low, or play "3D" mode of the game, many games now support "3D" mode, but according to the "3D" screen imaging principle, Required video memory is at least twice times the "2D" mode, then there is a multi-screen display, the more screen represents the higher the resolution will be displayed, the higher the resolution means that the need to deal with more screen data, the data need to be stored in memory, and the most direct memory is not enough video frame number is very low, has been very low, Do not want to be due to GPU or CPU performance is not enough part of the picture frame number of collapse phenomenon.

The meaning of memory bit width

Memory bit width is the role of video memory in a channel to the video card, if the phenomenon of memory bit width is in the case of resolution of the picture layered phenomenon, or the number of frames is very low, because the video card core can not get enough data to calculate, and then the graphics core will be idle will be realistic frame number average words, This shows the phenomenon of the card appears on the screen.

If the memory bit is not wide enough, you can choose a smaller resolution display, so that you can meet the normal reality needs, if 24 inches above the large screen, it is recommended to choose the video memory bit width 256-bit graphics card suitable. For example, a screen that supports 1920*1080 requires at least 128 bits of memory to be wide.
