Compare any two graphics cards:
GeForce GTX 560 Ti vs GeForce GTX 650 Ti
IntroThe GeForce GTX 560 Ti uses a 40 nm design. nVidia has set the core speed at 822 MHz. The GDDR5 memory is set to run at a frequency of 1002 MHz on this model. It features 384 SPUs along with 64 Texture Address Units and 32 ROPs.
Compare all of that to the GeForce GTX 650 Ti, which makes use of a 28 nm design. nVidia has set the core speed at 928 MHz. The GDDR5 memory is set to run at a speed of 1350 MHz on this particular model. It features 768 SPUs as well as 64 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 560 Ti will be 48% quicker than the GeForce GTX 650 Ti in general, due to its greater bandwidth. (explain)
Texel RateThe GeForce GTX 650 Ti will be a small bit (more or less 13%) better at AF than the GeForce GTX 560 Ti. (explain)
Pixel RateThe GeForce GTX 560 Ti will be much (more or less 77%) better at anti-aliasing than the GeForce GTX 650 Ti, 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: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better 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 number of texture map elements (texels) that are applied in one second. This is calculated 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
