Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs Radeon HD 3470 256MB
IntroThe GeForce 8600 GT 512MB DDR2 features a clock frequency of 540 MHz and a DDR2 memory frequency of 400 MHz. It also makes use of a 128-bit bus, and uses a 80 nm design. It is made up of 32 SPUs, 16 Texture Address Units, and 8 ROPs.Compare those specifications to the Radeon HD 3470 256MB, which has a core clock speed of 800 MHz and a DDR2 memory frequency of 950 MHz. It also uses a 128-bit memory bus, and makes use of a 55 nm design. It is made up of 40(8x5) SPUs, 4 TAUs, and 4 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the Radeon HD 3470 256MB will be 138% faster than the GeForce 8600 GT 512MB DDR2 overall, because of its higher bandwidth. (explain)
Texel RateThe GeForce 8600 GT 512MB DDR2 should be much (approximately 170%) better at texture filtering than the Radeon HD 3470 256MB. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce 8600 GT 512MB DDR2 is a better choice, 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 maximum amount of data (in units of MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's interface 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 bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units by the core 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 most pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. 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 is also dependant 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.
