Compare any two graphics cards:
Radeon HD 5750 512MB vs Radeon HD 6750 1GB
IntroThe Radeon HD 5750 512MB features a core clock speed of 700 MHz and a GDDR5 memory speed of 1150 MHz. It also uses a 128-bit bus, and uses a 40 nm design. It is made up of 720(144x5) SPUs, 36 TAUs, and 16 ROPs.Compare all 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 runs at a speed of 1000 MHz on this model. It features 720 SPUs along with 36 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthTheoretically speaking, the Radeon HD 5750 512MB should perform just a bit faster than the Radeon HD 6750 1GB overall. (explain)
Texel RateThe Radeon HD 6750 1GB is a little bit (about 4%) more effective at texture filtering than the Radeon HD 5750 512MB. (explain)
Pixel RateThe Radeon HD 6750 1GB is a small bit (about 4%) better at AA than the Radeon HD 5750 512MB, and also capable of handling higher resolutions without slowing down too much. (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: Memory bandwidth is the max amount of information (counted in MB per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range 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 texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
