Memory Bandwidth: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.

3 Responses to “GeForce GTX 580 vs Radeon HD 7970”hmmm it seems hd770 won in memory bus and texel rate but the 580 won the pixel rate, but who is the best among them?
yes the 7970 is the winner, because of its 140% win over the 580 in the texel rate 😀
AMD 7970 absolutely more fast than 580, but they still can't handle physx engine in some way they been kicked by Nvidia 2010 card technology.
it depend on your gaming needs and specification.
in this case (hi-end gaming) i am still in the "GREEN" side. they are fast as well.
but for my brothers PC i chose AMD beast gaming machine for the mid-end gaming.
