Compare any two graphics cards:

Geforce GTX 770 vs Radeon HD 7970

Intro

The Geforce GTX 770 comes with core clock speeds of 1046 MHz on the GPU, and 1753 MHz on the 2048 MB of GDDR5 memory. It features 1536 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

Compare those specs to the Radeon HD 7970, which has a core clock speed of 925 MHz and a GDDR5 memory speed of 1375 MHz. It also uses a 384-bit memory bus, and uses a 28 nm design. It is made up of 2048 SPUs, 128 Texture Address Units, and 32 ROPs.

Geforce GTX 770		224384 MB/sec
	Difference: 39616 (18%)

Texel Rate

The Geforce GTX 770 will be a little bit (about 13%) more effective at AF than the Radeon HD 7970. (explain)

Geforce GTX 770		133888 Mtexels/sec
Radeon HD 7970		118400 Mtexels/sec
	Difference: 15488 (13%)

Pixel Rate

The Geforce GTX 770 should be just a bit (about 13%) better at full screen anti-aliasing than the Radeon HD 7970, and should be capable of handling higher resolutions more effectively. (explain)

Geforce GTX 770		33472 Mpixels/sec
Radeon HD 7970		29600 Mpixels/sec
	Difference: 3872 (13%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of MB per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR type 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 can be applied per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.

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.
