Compare any two graphics cards:
GeForce GTX 970 vs Radeon HD 7950 3GB
IntroThe GeForce GTX 970 uses a 28 nm design. nVidia has set the core frequency at 1050 MHz. The GDDR5 memory works at a frequency of 1750 MHz on this model. It features 1664 SPUs as well as 104 Texture Address Units and 64 Rasterization Operator Units.Compare those specifications to the Radeon HD 7950 3GB, which comes with a core clock frequency of 800 MHz and a GDDR5 memory frequency of 1250 MHz. It also uses a 384-bit bus, and uses a 28 nm design. It is made up of 1792 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 7950 3GB should be 7% quicker than the GeForce GTX 970 overall, because of its higher data rate. (explain)
Texel RateThe GeForce GTX 970 will be a lot (about 22%) faster with regards to AF than the Radeon HD 7950 3GB. (explain)
Pixel RateThe GeForce GTX 970 will be much (about 163%) better at AA than the Radeon HD 7950 3GB, and able to handle higher screen resolutions without slowing down too much. (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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
