Compare any two graphics cards:
Geforce GTX 670 vs Geforce GTX 680
IntroThe Geforce GTX 670 has a GPU core clock speed of 915 MHz, and the 2048 MB of GDDR5 memory runs at 1500 MHz through a 256-bit bus. It also 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 clocked the core frequency at 1006 MHz. The GDDR5 memory works at a speed of 1502 MHz on this particular model. It features 1536 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Geforce GTX 680 is 0% faster than the Geforce GTX 670 overall, because of its greater data rate. (explain)
Texel RateThe Geforce GTX 680 will be quite a bit (about 26%) faster with regards to anisotropic filtering than the Geforce GTX 670. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Geforce GTX 680 is a better choice, though not by far. (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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units 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 applied per second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
