Compare any two graphics cards:
Geforce GTX 670 vs Geforce GTX 680
IntroThe Geforce GTX 670 comes with clock speeds of 915 MHz on the GPU, and 1500 MHz on the 2048 MB of GDDR5 RAM. It features 1344 SPUs as well as 112 TAUs and 32 Rasterization Operator Units.
Compare those specifications to the Geforce GTX 680, which uses a 28 nm design. nVidia has clocked the core speed at 1006 MHz. The GDDR5 RAM runs at a speed of 1502 MHz on this card. It features 1536 SPUs along with 128 TAUs and 32 ROPs.

Performance-wise, the Geforce GTX 680 should in theory be a small bit better than the Geforce GTX 670 in general. (explain)
Texel RateThe Geforce GTX 680 will be much (approximately 26%) better at texture filtering than the Geforce GTX 670. (explain)
Pixel RateThe Geforce GTX 680 is a bit (more or less 10%) faster with regards to full screen anti-aliasing than the Geforce GTX 670, and able to handle higher screen resolutions while still performing well. (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 information (in units of MB per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs 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 of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
