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

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 7750, in theory, should perform a bit faster than the Radeon HD 6750 overall. (explain)
Texel RateThe Radeon HD 6750 should be a small bit (about 2%) faster with regards to AF than the Radeon HD 7750. (explain)
Pixel RateThe Radeon HD 7750 is a bit (about 10%) faster with regards to FSAA than the Radeon HD 6750, and able to handle higher screen resolutions without slowing down too much. (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 max amount of data (counted in megabytes per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better 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 in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock 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 fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
