Compare any two graphics cards:
Radeon HD 3470 256MB vs Radeon HD 3650 256MB
IntroThe Radeon HD 3470 256MB features a GPU core clock speed of 800 MHz, and the 256 MB of DDR2 memory is set to run at 950 MHz through a 128-bit bus. It also is comprised of 40(8x5) Stream Processors, 4 TAUs, and 4 ROPs.Compare those specs to the Radeon HD 3650 256MB, which has core clock speeds of 725 MHz on the GPU, and 800 MHz on the 256 MB of DDR2 RAM. It features 120(24x5) SPUs along with 8 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon HD 3470 256MB should perform a small bit faster than the Radeon HD 3650 256MB overall. (explain)
Texel RateThe Radeon HD 3650 256MB will be much (approximately 81%) better at AF than the Radeon HD 3470 256MB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 3470 256MB is a better choice, not by a very large margin though. (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 largest amount of data (measured in megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 number of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the 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 the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill 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.
