Compare any two graphics cards:
Radeon HD 3650 vs Radeon HD 3650 512MB
IntroThe Radeon HD 3650 comes with a GPU core clock speed of 725 MHz, and the 1024 MB of GDDR4 RAM runs at 800 MHz through a 128-bit bus. It also is made up of 120(24x5) SPUs, 8 Texture Address Units, and 4 Raster Operation Units.Compare those specs to the Radeon HD 3650 512MB, which uses a 55 nm design. AMD has set the core speed at 725 MHz. The GDDR3 RAM works at a speed of 800 MHz on this specific card. It features 120(24x5) SPUs along with 8 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthBoth cards have exactly the same memory bandwidth, so in theory they should perform exactly the same. (explain)
Texel RateBoth cards have exactly the same texel rate, so theoretically they should perform equally good at at AF. (explain)Pixel RateBoth cards have exactly the same pixel rate, so theoretically they should perform equally good at at AA, and be able to handle the same screen resolutions. (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 (counted in MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
