Compare any two graphics cards:
Radeon HD 3850 X2 vs Radeon HD 6750 1GB
IntroThe Radeon HD 3850 X2 makes use of a 55 nm design. AMD has set the core frequency at 668 MHz. The GDDR3 memory is set to run at a speed of 828 MHz on this particular card. It features 320(64x5) SPUs along with 16 Texture Address Units and 16 ROPs.Compare that to the Radeon HD 6750 1GB, which makes use of a 40 nm design. AMD has clocked the core frequency at 725 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this model. It features 720 SPUs as well as 36 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon HD 3850 X2 should theoretically perform a lot faster than the Radeon HD 6750 1GB overall. (explain)
Texel RateThe Radeon HD 6750 1GB is a lot (about 22%) faster with regards to anisotropic filtering than the Radeon HD 3850 X2. (explain)
Pixel RateThe Radeon HD 3850 X2 should be a lot (about 84%) more effective at FSAA than the Radeon HD 6750 1GB, and also 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. 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 data (measured in megabytes per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
