Compare any two graphics cards:
Radeon HD 6870 vs Radeon HD 6950 2GB
IntroThe Radeon HD 6870 makes use of a 40 nm design. AMD has clocked the core frequency at 900 MHz. The GDDR5 memory runs at a frequency of 1050 MHz on this specific card. It features 1120 SPUs as well as 56 Texture Address Units and 32 Rasterization Operator Units.Compare that to the Radeon HD 6950 2GB, which features a clock speed of 800 MHz and a GDDR5 memory speed of 1250 MHz. It also features a 256-bit bus, and uses a 40 nm design. It is comprised of 1408 SPUs, 88 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 6950 2GB should theoretically be a small bit better than the Radeon HD 6870 overall. (explain)
Texel RateThe Radeon HD 6950 2GB will be quite a bit (more or less 40%) better at AF than the Radeon HD 6870. (explain)
Pixel RateThe Radeon HD 6870 will be just a bit (approximately 13%) faster with regards to FSAA than the Radeon HD 6950 2GB, and also should be able to handle higher screen resolutions while still performing well. (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 (measured in MB per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the 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 amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
