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 is set to run at a speed of 1050 MHz on this specific model. It features 1120 SPUs as well as 56 Texture Address Units and 32 ROPs.Compare those specifications to the Radeon HD 6950 2GB, which uses a 40 nm design. AMD has set the core speed at 800 MHz. The GDDR5 memory works at a frequency of 1250 MHz on this particular card. It features 1408 SPUs along with 88 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 6950 2GB should in theory be a little bit better than the Radeon HD 6870 overall. (explain)
Texel RateThe Radeon HD 6950 2GB will be a lot (about 40%) more effective at anisotropic filtering than the Radeon HD 6870. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon HD 6870 is superior to the Radeon HD 6950 2GB, 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 largest amount of information (measured in MB per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 per second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
