Compare any two graphics cards:
Radeon HD 3850 X2 vs Radeon HD 6750 1GB
IntroThe Radeon HD 3850 X2 uses a 55 nm design. AMD has clocked the core frequency at 668 MHz. The GDDR3 RAM is set to run at a speed of 828 MHz on this particular card. It features 320(64x5) SPUs as well as 16 Texture Address Units and 16 Rasterization Operator Units.Compare those specs to the Radeon HD 6750 1GB, which features a core clock frequency of 725 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 128-bit memory bus, and uses a 40 nm design. It features 720 SPUs, 36 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthAs far as performance goes, the Radeon HD 3850 X2 should in theory be a lot superior to the Radeon HD 6750 1GB in general. (explain)
Texel RateThe Radeon HD 6750 1GB will be a lot (approximately 22%) faster with regards to anisotropic filtering than the Radeon HD 3850 X2. (explain)
Pixel RateIf running with a high screen resolution 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 largest amount of information (measured in MB per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at 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 card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
