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 clocked the core speed at 822 MHz. The GDDR5 memory is set to run at a frequency of 1002 MHz on this particular card. It features 384 SPUs along with 64 TAUs and 32 ROPs.
Compare all of that to the GeForce GTX 650 Ti, which has a clock speed of 928 MHz and a GDDR5 memory speed of 1350 MHz. It also features a 128-bit memory bus, and uses a 28 nm design. It is comprised of 768 SPUs, 64 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 560 Ti should in theory be quite a bit faster than the GeForce GTX 650 Ti in general. (explain)
Texel RateThe GeForce GTX 650 Ti is a small bit (approximately 13%) better at anisotropic filtering than the GeForce GTX 560 Ti. (explain)
Pixel RateThe GeForce GTX 560 Ti is a lot (approximately 77%) faster with regards to full screen anti-aliasing than the GeForce GTX 650 Ti, and also able to handle higher resolutions without slowing down too much. (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 information (in units of megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the 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 the video card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
