Compare any two graphics cards:
Radeon HD 6750 vs Radeon HD 7750
IntroThe Radeon HD 6750 makes use of a 40 nm design. AMD has set the core frequency at 725 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this specific card. It features 720 SPUs as well as 36 TAUs and 16 ROPs.
Compare those specs to the Radeon HD 7750, which makes use of a 28 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 memory works at a frequency of 1125 MHz on this particular model. It features 512 SPUs along with 32 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the Radeon HD 7750 should be a small bit faster than the Radeon HD 6750 overall. (explain)
Texel RateThe Radeon HD 6750 should be a little bit (about 2%) more effective at anisotropic filtering than the Radeon HD 7750. (explain)
Pixel RateThe Radeon HD 7750 should be a little bit (about 10%) faster with regards to full screen anti-aliasing than the Radeon HD 6750, and also should be capable of handling higher screen 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: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics 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 maximum amount of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
