Compare any two graphics cards:
Radeon HD 6970 vs Radeon HD 7950 3GB
IntroThe Radeon HD 6970 has a GPU core speed of 880 MHz, and the 2048 MB of GDDR5 memory runs at 1375 MHz through a 256-bit bus. It also features 1536 SPUs, 96 TAUs, and 32 ROPs.Compare those specs to the Radeon HD 7950 3GB, which features core clock speeds of 800 MHz on the GPU, and 1250 MHz on the 3072 MB of GDDR5 memory. It features 1792 SPUs as well as 112 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 7950 3GB should be quite a bit faster than the Radeon HD 6970 in general. (explain)
Texel RateThe Radeon HD 7950 3GB will be a small bit (approximately 6%) faster with regards to AF than the Radeon HD 6970. (explain)
Pixel RateThe Radeon HD 6970 is just a bit (approximately 10%) more effective at full screen anti-aliasing than the Radeon HD 7950 3GB, and also will be capable of handling 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 max amount of data (measured in megabytes per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, 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 most pixels the video card can possibly record 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 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 output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
