Compare any two graphics cards:
Radeon HD 3850 512MB vs Radeon HD 6750
IntroThe Radeon HD 3850 512MB uses a 55 nm design. AMD has set the core speed at 668 MHz. The GDDR3 RAM runs at a frequency of 828 MHz on this specific model. It features 320(64x5) SPUs along with 16 TAUs and 16 ROPs.Compare those specifications to the Radeon HD 6750, which comes with a clock speed of 725 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 128-bit memory bus, and uses a 40 nm design. It is made up of 720 SPUs, 36 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 6750 is 21% faster than the Radeon HD 3850 512MB overall, due to its greater data rate. (explain)
Texel RateThe Radeon HD 6750 will be quite a bit (approximately 144%) faster with regards to anisotropic filtering than the Radeon HD 3850 512MB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon HD 6750 is the winner, but not 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 largest amount of information (measured in MB per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units of the card by the core clock 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 per second. Pixel Rate: Pixel rate is the maximum number 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 calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends 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 maximum fill rate.
