Compare any two graphics cards:
GeForce GTX 550 Ti vs GeForce GTX 560
IntroThe GeForce GTX 550 Ti makes use of a 40 nm design. nVidia has clocked the core frequency at 900 MHz. The GDDR5 RAM runs at a speed of 1026 MHz on this model. It features 192 SPUs as well as 32 Texture Address Units and 24 Rasterization Operator Units.
Compare those specs to the GeForce GTX 560, which uses a 40 nm design. nVidia has clocked the core frequency at 810 MHz. The GDDR5 RAM works at a speed of 1001 MHz on this particular card. It features 336 SPUs along with 56 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 560 should theoretically perform quite a bit faster than the GeForce GTX 550 Ti overall. (explain)
Texel RateThe GeForce GTX 560 should be much (approximately 58%) more effective at AF than the GeForce GTX 550 Ti. (explain)
Pixel RateThe GeForce GTX 560 should be a small bit (about 20%) faster with regards to full screen anti-aliasing than the GeForce GTX 550 Ti, and should be capable of handling 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 MB per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out 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 filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
