Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs Radeon HD 6950 2GB
IntroThe GeForce 8600 GT 512MB DDR2 has a core clock speed of 540 MHz and a DDR2 memory frequency of 400 MHz. It also features a 128-bit memory bus, and makes use of a 80 nm design. It is made up of 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.Compare all of that to the Radeon HD 6950 2GB, which has a core 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 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 6950 2GB should perform much faster than the GeForce 8600 GT 512MB DDR2 in general. (explain)
Texel RateThe Radeon HD 6950 2GB should be much (approximately 715%) better at texture filtering than the GeForce 8600 GT 512MB DDR2. (explain)
Pixel RateThe Radeon HD 6950 2GB will be quite a bit (about 493%) faster with regards to full screen anti-aliasing than the GeForce 8600 GT 512MB DDR2, and also should be capable of handling higher screen resolutions better. (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 MB per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs 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 fill rate is also dependant 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 max fill rate.
