Compare any two graphics cards:
Radeon HD 3470 512MB vs Radeon HD 3650
IntroThe Radeon HD 3470 512MB uses a 55 nm design. AMD has set the core speed at 800 MHz. The GDDR3 memory is set to run at a speed of 950 MHz on this model. It features 40(8x5) SPUs as well as 4 TAUs and 4 Rasterization Operator Units.Compare those specs to the Radeon HD 3650, which features a clock frequency of 725 MHz and a GDDR4 memory speed of 800 MHz. It also features a 128-bit memory bus, and makes use of a 55 nm design. It is comprised of 120(24x5) SPUs, 8 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon HD 3470 512MB, in theory, should be a bit faster than the Radeon HD 3650 overall. (explain)
Texel RateThe Radeon HD 3650 will be quite a bit (about 81%) better at anisotropic filtering than the Radeon HD 3470 512MB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon HD 3470 512MB is the winner, but it probably won't make a huge difference. (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 information (measured in MB per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
