Compare any two graphics cards:
GeForce GTX 560 vs GeForce GTX 560 Ti
IntroThe GeForce GTX 560 has core speeds of 810 MHz on the GPU, and 1001 MHz on the 1024 MB of GDDR5 RAM. It features 336 SPUs as well as 56 Texture Address Units and 32 Rasterization Operator Units.
Compare all of that to the GeForce GTX 560 Ti, which features core speeds of 822 MHz on the GPU, and 1002 MHz on the 1024 MB of GDDR5 RAM. It features 384 SPUs as well as 64 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 560 Ti will be 0% faster than the GeForce GTX 560 overall, because of its greater bandwidth. (explain)
Texel RateThe GeForce GTX 560 Ti will be a little bit (more or less 16%) more effective at anisotropic filtering than the GeForce GTX 560. (explain)
Pixel RateThe GeForce GTX 560 Ti is just a bit (approximately 1%) better at anti-aliasing than the GeForce GTX 560, and will be capable of handling higher screen resolutions without losing too much performance. (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 largest amount of information (in units of MB per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR memory, it must 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 anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of 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 amount of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called 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 reach the maximum fill rate.
