Compare any two graphics cards:
Radeon HD 3470 256MB vs Radeon HD 6750
IntroThe Radeon HD 3470 256MB uses a 55 nm design. AMD has clocked the core frequency at 800 MHz. The DDR2 memory runs at a speed of 950 MHz on this specific card. It features 40(8x5) SPUs along with 4 TAUs and 4 Rasterization Operator Units.Compare that to the Radeon HD 6750, which features GPU clock speed of 725 MHz, and 512 MB of GDDR5 RAM set to run at 1000 MHz through a 128-bit bus. It also is made up of 720 Stream Processors, 36 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon HD 6750 is 111% quicker than the Radeon HD 3470 256MB overall, because of its greater data rate. (explain)
Texel RateThe Radeon HD 6750 will be a lot (about 716%) more effective at AF than the Radeon HD 3470 256MB. (explain)
Pixel RateThe Radeon HD 6750 will be quite a bit (more or less 263%) more effective at anti-aliasing than the Radeon HD 3470 256MB, and should be able to handle higher resolutions better. (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 max amount of data (counted in MB per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 can be applied per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, 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 number of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units 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 output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
