Compare any two graphics cards:
Geforce GTX 760 vs Radeon HD 6950
IntroThe Geforce GTX 760 features a clock speed of 980 MHz and a GDDR5 memory frequency of 1502 MHz. It also makes use of a 256-bit memory bus, and uses a 28 nm design. It features 1152 SPUs, 96 Texture Address Units, and 32 Raster Operation Units.
Compare those specifications to the Radeon HD 6950, which uses a 40 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 memory is set to run at a frequency of 1250 MHz on this particular card. It features 1408 SPUs along with 88 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the Geforce GTX 760 should perform a little bit faster than the Radeon HD 6950 in general. (explain)
Texel RateThe Geforce GTX 760 is quite a bit (more or less 34%) better at texture filtering than the Radeon HD 6950. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Geforce GTX 760 is a better choice, by far. (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: Bandwidth is the largest amount of data (in units of MB per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
