Compare any two graphics cards:
Radeon HD 5750 512MB vs Radeon HD 6770 1GB
IntroThe Radeon HD 5750 512MB makes use of a 40 nm design. AMD has clocked the core speed at 700 MHz. The GDDR5 RAM is set to run at a speed of 1150 MHz on this specific card. It features 720(144x5) SPUs as well as 36 TAUs and 16 Rasterization Operator Units.Compare those specifications to the Radeon HD 6770 1GB, which comes with core clock speeds of 900 MHz on the GPU, and 1050 MHz on the 1024 MB of GDDR5 RAM. It features 800 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 5750 512MB should in theory be a small bit better than the Radeon HD 6770 1GB overall. (explain)
Texel RateThe Radeon HD 6770 1GB will be a lot (about 43%) faster with regards to AF than the Radeon HD 5750 512MB. (explain)
Pixel RateThe Radeon HD 6770 1GB should be quite a bit (more or less 29%) faster with regards to AA than the Radeon HD 5750 512MB, and also capable of handling higher resolutions better. (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 maximum amount of data (measured in megabytes per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling 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 could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
