Compare any two graphics cards:
Radeon HD 6770 vs Radeon HD 7750
IntroThe Radeon HD 6770 has a clock speed of 900 MHz and a GDDR5 memory frequency of 1050 MHz. It also uses a 128-bit memory bus, and uses a 40 nm design. It features 800 SPUs, 40 TAUs, and 16 ROPs.Compare that to the Radeon HD 7750, which makes use of a 28 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 memory works at a speed of 1125 MHz on this model. It features 512 SPUs as well as 32 TAUs and 16 ROPs.

3DMark Fire Strike Graphics Score
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 7750 is 7% quicker than the Radeon HD 6770 overall, because of its greater data rate. (explain)
Texel RateThe Radeon HD 6770 should be quite a bit (more or less 41%) more effective at anisotropic filtering than the Radeon HD 7750. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon HD 6770 is the winner, not by a very large margin though. (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: Bandwidth is the largest amount of data (measured in MB per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
