Compare any two graphics cards:
Radeon HD 6750 vs Radeon HD 7770
IntroThe Radeon HD 6750 uses a 40 nm design. ATi has clocked the core speed at 725 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this specific card. It features 720 SPUs as well as 36 TAUs and 16 Rasterization Operator Units.
Compare those specifications to the Radeon HD 7770, which uses a 28 nm design. ATi has clocked the core speed at 1000 MHz. The GDDR5 RAM runs at a speed of 1125 MHz on this particular card. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon HD 7770 should in theory be a little bit faster than the Radeon HD 6750 overall. (explain)
Texel RateThe Radeon HD 7770 is much (more or less 53%) more effective at texture filtering than the Radeon HD 6750. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon HD 7770 is a better choice, 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 ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 processed in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
