If you have a new PC (or a PC with an upgrade), please note the following: the graphics cards recommended later are mainly for new PCs. MPEG-2 for "standard" DVD, MPEG-4 / h.264 and VC-1 from Microsoft for HD DVD and Blue Ray. VC-1: all ATI HD 3000 series and all GeForce 9000 series (except 9600 GT).MPEG4 / h.264: all ATI HD 2000 series cards (except for HD 2900) and above, all GeForce 8000 series (except for the old 8800) and above.

MPEG-2: all ATI Series X 1000 and above, all GeForce 7000 and above.

Video Card Performanceįor reading different video formats, full format decoding with a video card looks like this: The graphic bus provides the connection between the graphical card and the rest of the PC. A 256-bit bus is more efficient than a 128-bit bus for the same GPU and the same memory. As a rule, the larger the bus, the faster the exchange between the GPU and memory. The bit rate of this bus is important: it can be 64, 128, 256, 384 and 512 bits. The memory bus connects the GPU and memory to exchange data between them. Besides the memory capacity, the memory frequency is also very important: the higher the number, the better the card. The memory type has evolved over time: G-DDR2, G-DDR3, G-DDR4, G-DDR5: the higher the number, the faster the memory. Tests conducted by Hardware Magazine in late 2013 with high detail Full HD and AA included show that while some "light" games use 1-3 GB of memory (Batman Origins, Grid 2, Dirt Showdown, Metro Last Night, Bioshock), most modern video games require 3 to 8 GB. 10 GB and above is the standard for high-end,.8 GB is the standard for the medium level,.3 GB is the minimum recommended memory at this time.Modern games use the GDDR5 memory standard. The video card memory stores intermediate data, which is then displayed on the monitor. The most important are thread processors: the more thread processors there are, the more powerful the GPU (for a given architecture) will be. Raster Operations Pipeline (ROP) blocks responsible for the last pixel operations, such as smoothing but also mixing and Z-buffer.

Texture blocks (TMU), responsible for the processing of textures that will be applied to each pixel.

Stream Processor (SP) - makes most calculations by pixels and vertices, which make up elementary triangles when rendering images.

The modern graphics processor is based on different computing devices: The graphics processor is an important component of the graphics card, it will determine the performance. Video Card Structure Graphics Processor (GPU)

Professional 3D applications require a professional graphics card.

For 3D video games, a more powerful graphics card is required.

For multimedia applications you need a video card that can play video in the desired format.

For office applications, a built-in chip or a basic video card is sufficient.

When choosing this item, you should consider your specific needs as well as its cost:
