Compare any two graphics cards:
Geforce GTX 760 vs Radeon HD 6950
IntroThe Geforce GTX 760 has a GPU core speed of 980 MHz, and the 2048 MB of GDDR5 RAM is set to run at 1502 MHz through a 256-bit bus. It also is made up of 1152 Stream Processors, 96 TAUs, and 32 ROPs.
Compare those specs to the Radeon HD 6950, which has core speeds of 800 MHz on the GPU, and 1250 MHz on the 1024 MB of GDDR5 RAM. It features 1408 SPUs as well as 88 TAUs and 32 ROPs.

Power Consumption (Max TDP)
As far as performance goes, the Geforce GTX 760 should theoretically be a little bit better than the Radeon HD 6950 overall. (explain)
Texel RateThe Geforce GTX 760 will be much (about 34%) more effective at AF than the Radeon HD 6950. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Geforce GTX 760 is superior to the Radeon HD 6950, by a large margin. (explain)
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 (measured in MB per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
