Compare any two graphics cards:
GeForce GTX 550 Ti vs GeForce GTX 560 Ti
IntroThe GeForce GTX 550 Ti uses a 40 nm design. nVidia has clocked the core speed at 900 MHz. The GDDR5 RAM works at a speed of 1026 MHz on this particular model. It features 192 SPUs as well as 32 Texture Address Units and 24 ROPs.
Compare those specifications to the GeForce GTX 560 Ti, which makes use of a 40 nm design. nVidia has set the core frequency at 822 MHz. The GDDR5 RAM is set to run at a frequency of 1002 MHz on this model. It features 384 SPUs as well as 64 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 560 Ti, in theory, should be quite a bit faster than the GeForce GTX 550 Ti in general. (explain)
Texel RateThe GeForce GTX 560 Ti should be much (about 83%) more effective at texture filtering than the GeForce GTX 550 Ti. (explain)
Pixel RateThe GeForce GTX 560 Ti will be much (about 22%) better at FSAA than the GeForce GTX 550 Ti, and also 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: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at 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 chip could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
