Compare any two graphics cards:
Radeon HD 3470 256MB vs Radeon HD 6950 2GB
IntroThe Radeon HD 3470 256MB comes with a clock frequency of 800 MHz and a DDR2 memory frequency of 950 MHz. It also features 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 Raster Operation Units.Compare those specifications to the Radeon HD 6950 2GB, which makes use of a 40 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 memory runs at a frequency of 1250 MHz on this specific model. It features 1408 SPUs along with 88 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthAs far as performance goes, the Radeon HD 6950 2GB should in theory be quite a bit better than the Radeon HD 3470 256MB overall. (explain)
Texel RateThe Radeon HD 6950 2GB is quite a bit (about 2100%) better at texture filtering than the Radeon HD 3470 256MB. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon HD 6950 2GB is the winner, and very much so. (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 over the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has 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 anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
