Compare any two graphics cards:
GeForce 8800 GT 1GB vs Radeon HD 6950
IntroThe GeForce 8800 GT 1GB makes use of a 65 nm design. nVidia has clocked the core frequency at 600 MHz. The GDDR3 RAM is set to run at a frequency of 900 MHz on this particular model. It features 112 SPUs as well as 56 TAUs and 16 ROPs.Compare all of that to the Radeon HD 6950, which has core clock speeds of 800 MHz on the GPU, and 1250 MHz on the 1024 MB of GDDR5 memory. It features 1408 SPUs as well as 88 TAUs and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 6950 should in theory be a lot superior to the GeForce 8800 GT 1GB in general. (explain)
Texel RateThe Radeon HD 6950 will be quite a bit (about 110%) better at AF than the GeForce 8800 GT 1GB. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon HD 6950 is the winner, by far. (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 over the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the card will be at handling 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 card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number 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 rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
