Compare any two graphics cards:
Geforce GTX 680 vs Geforce GTX 770
IntroThe Geforce GTX 680 has clock speeds of 1006 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 memory. It features 1536 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.
Compare those specifications to the Geforce GTX 770, which has GPU core speed of 1046 MHz, and 2048 MB of GDDR5 RAM set to run at 1753 MHz through a 256-bit bus. It also is comprised of 1536 Stream Processors, 128 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Geforce GTX 770 is 17% quicker than the Geforce GTX 680 overall, because of its greater data rate. (explain)
Texel RateThe Geforce GTX 770 will be a little bit (about 4%) better at AF than the Geforce GTX 680. (explain)
Pixel RateThe Geforce GTX 770 will be a small bit (more or less 4%) faster with regards to AA than the Geforce GTX 680, and also should be capable of handling higher resolutions better. (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 largest amount of information (in units of megabytes per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 processed in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on 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 maximum fill rate.
