Compare any two graphics cards:
Radeon HD 6950 vs Radeon HD 7750
IntroThe Radeon HD 6950 makes use of a 40 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 memory runs at a speed of 1250 MHz on this particular model. It features 1408 SPUs along with 88 Texture Address Units and 32 Rasterization Operator Units.
Compare those specs to the Radeon HD 7750, which uses a 28 nm design. AMD has set the core speed at 800 MHz. The GDDR5 memory is set to run at a speed of 1125 MHz on this specific card. It features 512 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the Radeon HD 6950 should in theory be quite a bit superior to the Radeon HD 7750 in general. (explain)
Texel RateThe Radeon HD 6950 is quite a bit (about 175%) more effective at texture filtering than the Radeon HD 7750. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon HD 6950 is a better choice, by a large margin. (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.

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
