Compare any two graphics cards:
Radeon HD 5670 vs Radeon HD 5770
IntroThe Radeon HD 5670 features clock speeds of 775 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 400(80x5) SPUs as well as 20 TAUs and 8 ROPs.
Compare all of that to the Radeon HD 5770, which makes use of a 40 nm design. AMD has set the core speed at 850 MHz. The GDDR5 RAM runs at a frequency of 1200 MHz on this particular card. It features 800(160x5) SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the Radeon HD 5770 should theoretically be a bit better than the Radeon HD 5670 in general. (explain)
Texel RateThe Radeon HD 5770 will be quite a bit (approximately 119%) faster with regards to anisotropic filtering than the Radeon HD 5670. (explain)
Pixel RateThe Radeon HD 5770 should be much (about 119%) faster with regards to FSAA than the Radeon HD 5670, and 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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the interface 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 4 instead. The better the bandwidth is, the faster 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 figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video 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 maximum amount of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
