Compare any two graphics cards:
Radeon HD 5750 1GB vs Radeon HD 5750 512MB
IntroThe Radeon HD 5750 1GB features a core clock frequency of 700 MHz and a GDDR5 memory speed of 1150 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It is comprised of 720(144x5) SPUs, 36 Texture Address Units, and 16 Raster Operation Units.Compare that to the Radeon HD 5750 512MB, which uses a 40 nm design. AMD has clocked the core frequency at 700 MHz. The GDDR5 RAM works at a frequency of 1150 MHz on this model. It features 720(144x5) SPUs along with 36 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthBoth cards have the exact same bandwidth, so in theory they should perform exactly the same. (explain)
Texel RateBoth cards have exactly the same texel rate, so theoretically they should be equally good at at AF. (explain)Pixel RateBoth cards have the exact same pixel fill rate, so theoretically they should be equally good at at AA, and be able to handle the same screen resolutions. (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: Bandwidth is the largest amount of data (in units of megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 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 better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines 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 rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
