Compare any two graphics cards:
GeForce 9800 GTX vs Radeon HD 3470 512MB
IntroThe GeForce 9800 GTX comes with a core clock speed of 675 MHz and a GDDR3 memory speed of 1100 MHz. It also features a 256-bit memory bus, and uses a 65 nm design. It features 128 SPUs, 64 TAUs, and 16 ROPs.Compare those specs to the Radeon HD 3470 512MB, which comes with clock speeds of 800 MHz on the GPU, and 950 MHz on the 512 MB of GDDR3 memory. It features 40(8x5) SPUs along with 4 Texture Address Units and 4 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the GeForce 9800 GTX should perform a lot faster than the Radeon HD 3470 512MB overall. (explain)
Texel RateThe GeForce 9800 GTX is a lot (about 1250%) better at anisotropic filtering than the Radeon HD 3470 512MB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce 9800 GTX is superior to the Radeon HD 3470 512MB, 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 max amount of data (measured in megabytes per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
