Compare any two graphics cards:
GeForce GTX 580 vs Radeon HD 7750
IntroThe GeForce GTX 580 uses a 40 nm design. nVidia has set the core speed at 772 MHz. The GDDR5 memory works at a frequency of 1002 MHz on this model. It features 512 SPUs as well as 64 Texture Address Units and 48 ROPs.
Compare those specs to the Radeon HD 7750, which uses a 28 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 memory works at a frequency of 1125 MHz on this particular card. It features 512 SPUs along with 32 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 580 should theoretically be quite a bit better than the Radeon HD 7750 overall. (explain)
Texel RateThe GeForce GTX 580 should be quite a bit (about 93%) more effective at AF than the Radeon HD 7750. (explain)
Pixel RateThe GeForce GTX 580 will be a lot (more or less 190%) more effective at full screen anti-aliasing than the Radeon HD 7750, and also capable of handling higher resolutions without losing too much performance. (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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 processed in one second. This number is worked out by multiplying the total texture units by the core 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 applied in a second.
Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core 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 many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
