Compare any two graphics cards:
Radeon HD 3470 256MB vs Radeon HD 3650
IntroThe Radeon HD 3470 256MB has a GPU core speed of 800 MHz, and the 256 MB of DDR2 RAM 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 Raster Operation Units.Compare that to the Radeon HD 3650, which features core speeds of 725 MHz on the GPU, and 800 MHz on the 1024 MB of GDDR4 RAM. It features 120(24x5) SPUs as well as 8 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon HD 3470 256MB should theoretically perform a small bit faster than the Radeon HD 3650 overall. (explain)
Texel RateThe Radeon HD 3650 should be quite a bit (more or less 81%) faster with regards to AF than the Radeon HD 3470 256MB. (explain)
Pixel RateThe Radeon HD 3470 256MB is a small bit (approximately 10%) faster with regards to full screen anti-aliasing than the Radeon HD 3650, and will be capable of handling higher screen resolutions more effectively. (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 data (counted in megabytes per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel 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 potential to reach the maximum fill rate.
