Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its 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 card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum 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
Add GHZ edition please
The Core Speed and Pixel Rate is wrong about 7970, fix this!
