Compare any two graphics cards:
Radeon HD 3850 X2 vs Radeon HD 7750
IntroThe Radeon HD 3850 X2 comes with a GPU clock speed of 668 MHz, and the 512 MB of GDDR3 memory is set to run at 828 MHz through a 256-bit bus. It also features 320(64x5) Stream Processors, 16 Texture Address Units, and 16 ROPs.Compare those specifications to the Radeon HD 7750, which makes use of a 28 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 memory is set to run at a frequency of 1125 MHz on this specific model. It features 512 SPUs as well as 32 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon HD 3850 X2 should in theory perform quite a bit faster than the Radeon HD 7750 in general. (explain)
Texel RateThe Radeon HD 7750 is a little bit (more or less 20%) more effective at anisotropic filtering than the Radeon HD 3850 X2. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon HD 3850 X2 is superior to the Radeon HD 7750, by far. (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: Bandwidth is the max amount of information (counted in MB per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core 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 applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
