Compare any two graphics cards:
Radeon HD 5670 vs Radeon HD 6770 1GB
IntroThe Radeon HD 5670 makes use of a 40 nm design. AMD has set the core speed at 775 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this particular model. It features 400(80x5) SPUs as well as 20 TAUs and 8 Rasterization Operator Units.Compare all of that to the Radeon HD 6770 1GB, which features GPU core speed of 900 MHz, and 1024 MB of GDDR5 memory set to run at 1050 MHz through a 128-bit bus. It also features 800 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 6770 1GB should theoretically be just a bit better than the Radeon HD 5670 overall. (explain)
Texel RateThe Radeon HD 6770 1GB will be quite a bit (more or less 132%) better at AF than the Radeon HD 5670. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon HD 6770 1GB is superior to the Radeon HD 5670, 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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of data (measured 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 interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once 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 anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
