Compare any two graphics cards:
Radeon HD 6950 vs Radeon HD 7870 XT
IntroThe Radeon HD 6950 makes use of a 40 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 RAM runs at a speed of 1250 MHz on this specific card. It features 1408 SPUs along with 88 TAUs and 32 Rasterization Operator Units.Compare all of that to the Radeon HD 7870 XT, which comes with a core clock frequency of 925 MHz and a GDDR5 memory frequency of 1500 MHz. It also uses a 256-bit bus, and makes use of a 28 nm design. It features 1536 SPUs, 96 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 7870 XT should theoretically be a bit faster than the Radeon HD 6950 overall. (explain)
Texel RateThe Radeon HD 7870 XT will be much (more or less 26%) more effective at anisotropic filtering than the Radeon HD 6950. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon HD 7870 XT is a better choice, not by a very large margin though. (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 max amount of information (measured in megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics 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 amount of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
