Compare any two graphics cards:
GeForce GTX 660 vs Geforce GTX 760
IntroThe GeForce GTX 660 uses a 28 nm design. nVidia has set the core frequency at 980 MHz. The GDDR5 memory works at a speed of 1502 MHz on this card. It features 960 SPUs along with 80 TAUs and 24 Rasterization Operator Units.
Compare all of that to the Geforce GTX 760, which features clock speeds of 980 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 memory. It features 1152 SPUs as well as 96 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Geforce GTX 760 will be 33% faster than the GeForce GTX 660 in general, due to its higher bandwidth. (explain)
Texel RateThe Geforce GTX 760 is a bit (approximately 20%) more effective at texture filtering than the GeForce GTX 660. (explain)
Pixel RateThe Geforce GTX 760 is much (approximately 33%) faster with regards to anti-aliasing than the GeForce GTX 660, and also should be able to handle higher screen 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: Memory bandwidth is the largest amount of information (counted in MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units of the card by the core 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 processed in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number 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 fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
