Memory Bandwidth: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). 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 get to the max fill rate.

5 Responses to “Geforce GTX 770 vs Radeon HD 7970”which card is better a msi r7970 lightning or evga 770 titan cooled ?
becouse i have a r7970 lightning.. :S
Depends, For video editing yes for most games, No. AMD Cards are better for Video editing and better at some games but Nividia is better for gaming, especially on the really popular games, BF3,Far Cry 3 ect... Those cards are pretty close though. The Asus 7970 ROG Matrix is better than the Lightning because of it's better cooling and heat dissipation. The 7970 ROG Matrix is also clocked to 316 GB/s and is much quieter and cooler than reference and lightning 7970's.
Add GHZ edition please

The Core Speed and Pixel Rate is wrong about 7970, fix this!
