Compare any two graphics cards:
Radeon HD 3470 512MB vs Radeon HD 3650 256MB
IntroThe Radeon HD 3470 512MB makes use of a 55 nm design. AMD has clocked the core speed at 800 MHz. The GDDR3 RAM runs at a speed of 950 MHz on this specific model. It features 40(8x5) SPUs as well as 4 Texture Address Units and 4 ROPs.Compare those specifications to the Radeon HD 3650 256MB, which features GPU core speed of 725 MHz, and 256 MB of DDR2 memory set to run at 800 MHz through a 128-bit bus. It also features 120(24x5) SPUs, 8 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the Radeon HD 3470 512MB should perform just a bit faster than the Radeon HD 3650 256MB overall. (explain)
Texel RateThe Radeon HD 3650 256MB will be much (about 81%) better at anisotropic filtering than the Radeon HD 3470 512MB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon HD 3470 512MB is superior to the Radeon HD 3650 256MB, but not 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: Bandwidth is the max amount of information (counted in MB per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). 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 potential to reach the maximum fill rate.
