Compare any two graphics cards:
Geforce GTX 670 vs Geforce GTX 680
IntroThe Geforce GTX 670 comes with a clock frequency of 915 MHz and a GDDR5 memory speed of 1500 MHz. It also uses a 256-bit memory bus, and makes use of a 28 nm design. It is made up of 1344 SPUs, 112 TAUs, and 32 Raster Operation Units.
Compare that to the Geforce GTX 680, which makes use of a 28 nm design. nVidia has set the core speed at 1006 MHz. The GDDR5 RAM runs at a speed of 1502 MHz on this specific card. It features 1536 SPUs along with 128 Texture Address Units and 32 Rasterization Operator Units.

As far as performance goes, the Geforce GTX 680 should in theory be a small bit superior to the Geforce GTX 670 in general. (explain)
Texel RateThe Geforce GTX 680 will be quite a bit (more or less 26%) better at texture filtering than the Geforce GTX 670. (explain)
Pixel RateThe Geforce GTX 680 is a small bit (more or less 10%) better at anti-aliasing than the Geforce GTX 670, and will be 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 largest amount of data (measured in megabytes per second) that can be moved past the external memory interface within a 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 must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
