Geforce GTX 770 vs Radeon HD 7970
Intro
The Geforce GTX 770 makes use of a 28 nm design. nVidia has clocked the core frequency at 1046 MHz. The GDDR5 memory works at a speed of 1753 MHz on this particular model. It features 1536 SPUs as well as 128 TAUs and 32 ROPs.Compare those specs to the Radeon HD 7970, which has a GPU core clock speed of 925 MHz, and 3072 MB of GDDR5 RAM running at 1375 MHz through a 384-bit bus. It also is made up of 2048 Stream Processors, 128 Texture Address Units, and 32 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the 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
Add GHZ edition please
The Core Speed and Pixel Rate is wrong about 7970, fix this!
