Compare any two graphics cards:
GeForce GTX 560 vs GeForce GTX 560 Ti
IntroThe GeForce GTX 560 makes use of a 40 nm design. nVidia has clocked the core speed at 810 MHz. The GDDR5 RAM works at a speed of 1001 MHz on this specific card. It features 336 SPUs along with 56 Texture Address Units and 32 ROPs.
Compare that to the GeForce GTX 560 Ti, which has GPU clock speed of 822 MHz, and 1024 MB of GDDR5 memory running at 1002 MHz through a 256-bit bus. It also is comprised of 384 SPUs, 64 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 560 Ti should theoretically be a small bit better than the GeForce GTX 560 in general. (explain)
Texel RateThe GeForce GTX 560 Ti will be a little bit (approximately 16%) more effective at anisotropic filtering than the GeForce GTX 560. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 560 Ti is superior to the GeForce GTX 560, though only just barely. (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: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video 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 that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
