Compare any two graphics cards:
Radeon HD 5750 1GB vs Radeon HD 6770 1GB
IntroThe Radeon HD 5750 1GB features clock speeds of 700 MHz on the GPU, and 1150 MHz on the 1024 MB of GDDR5 memory. It features 720(144x5) SPUs as well as 36 Texture Address Units and 16 Rasterization Operator Units.Compare all that to the Radeon HD 6770 1GB, which features core clock speeds of 900 MHz on the GPU, and 1050 MHz on the 1024 MB of GDDR5 memory. It features 800 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 5750 1GB should perform a little bit faster than the Radeon HD 6770 1GB in general. (explain)
Texel RateThe Radeon HD 6770 1GB should be quite a bit (about 43%) faster with regards to texture filtering than the Radeon HD 5750 1GB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon HD 6770 1GB is a better choice, and very much so. (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 a second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core 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 fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
