Compare any two graphics cards:
GeForce GTX 460 vs GeForce GTX 560 Ti
IntroThe GeForce GTX 460 comes with a GPU core speed of 675 MHz, and the 768 MB of GDDR5 RAM is set to run at 900 MHz through a 192-bit bus. It also is made up of 336 SPUs, 56 Texture Address Units, and 24 Raster Operation Units.
Compare those specifications to the GeForce GTX 560 Ti, which has a GPU core clock speed of 822 MHz, and 1024 MB of GDDR5 memory set to run at 1002 MHz through a 256-bit bus. It also is made up of 384 Stream Processors, 64 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 560 Ti should in theory be much faster than the GeForce GTX 460 in general. (explain)
Texel RateThe GeForce GTX 560 Ti will be much (more or less 39%) faster with regards to texture filtering than the GeForce GTX 460. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTX 560 Ti is the winner, and very much so. (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 max amount of information (in units of MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
