Compare any two graphics cards:
Radeon HD 6970 vs Radeon HD 7870 XT
IntroThe Radeon HD 6970 features a GPU clock speed of 880 MHz, and the 2048 MB of GDDR5 memory is set to run at 1375 MHz through a 256-bit bus. It also is comprised of 1536 Stream Processors, 96 Texture Address Units, and 32 Raster Operation Units.Compare all that to the Radeon HD 7870 XT, which has GPU clock speed of 925 MHz, and 2048 MB of GDDR5 RAM set to run at 1500 MHz through a 256-bit bus. It also features 1536 Stream Processors, 96 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 7870 XT, in theory, should be a little bit faster than the Radeon HD 6970 in general. (explain)
Texel RateThe Radeon HD 7870 XT should be a bit (approximately 5%) faster with regards to AF than the Radeon HD 6970. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon HD 7870 XT is superior to the Radeon HD 6970, but only just. (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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure 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 filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
