Compare any two graphics cards:
Radeon HD 5750 1GB vs Radeon HD 6950 2GB
IntroThe Radeon HD 5750 1GB has a GPU core clock speed of 700 MHz, and the 1024 MB of GDDR5 RAM runs at 1150 MHz through a 128-bit bus. It also features 720(144x5) SPUs, 36 TAUs, and 16 Raster Operation Units.Compare all that to the Radeon HD 6950 2GB, which features core speeds of 800 MHz on the GPU, and 1250 MHz on the 2048 MB of GDDR5 RAM. It features 1408 SPUs as well as 88 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 6950 2GB should be much faster than the Radeon HD 5750 1GB in general. (explain)
Texel RateThe Radeon HD 6950 2GB will be much (approximately 179%) more effective at AF than the Radeon HD 5750 1GB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon HD 6950 2GB is a better choice, by a large margin. (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 (counted in megabytes per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, 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 clock speed of the chip. The better the texel rate, the better the video 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 the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
