Compare any two graphics cards:
Radeon HD 7870 XT vs Radeon HD 7970
IntroThe Radeon HD 7870 XT uses a 28 nm design. AMD has set the core speed at 925 MHz. The GDDR5 memory is set to run at a frequency of 1500 MHz on this particular model. It features 1536 SPUs as well as 96 Texture Address Units and 32 ROPs.Compare those specifications to the Radeon HD 7970, which uses a 28 nm design. AMD has set the core speed at 925 MHz. The GDDR5 RAM runs at a speed of 1375 MHz on this particular model. It features 2048 SPUs along with 128 TAUs and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 7970, in theory, should be quite a bit faster than the Radeon HD 7870 XT in general. (explain)
Texel RateThe Radeon HD 7970 should be quite a bit (approximately 33%) better at anisotropic filtering than the Radeon HD 7870 XT. (explain)
Pixel RateBoth cards have exactly the same pixel fill rate, so theoretically they should be equally good at at FSAA, and be able to handle the same screen resolutions. (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 largest amount of data (in units of MB per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
