Compare any two graphics cards:
Radeon HD 3850 X2 vs Radeon HD 6750
IntroThe Radeon HD 3850 X2 uses a 55 nm design. AMD has set the core speed at 668 MHz. The GDDR3 memory is set to run at a frequency of 828 MHz on this specific card. It features 320(64x5) SPUs as well as 16 TAUs and 16 ROPs.Compare that to the Radeon HD 6750, which uses a 40 nm design. AMD has set the core speed at 725 MHz. The GDDR5 RAM works at a frequency of 1000 MHz on this specific model. It features 720 SPUs as well as 36 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthAs far as performance goes, the Radeon HD 3850 X2 should in theory be much better than the Radeon HD 6750 overall. (explain)
Texel RateThe Radeon HD 6750 is much (about 22%) better at AF than the Radeon HD 3850 X2. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon HD 3850 X2 is a better choice, by a large margin. (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. One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR 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 number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the 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 number of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
