Compare any two graphics cards:
GeForce GTX 550 Ti vs GeForce GTX 560 Ti
IntroThe GeForce GTX 550 Ti makes use of a 40 nm design. nVidia has clocked the core speed at 900 MHz. The GDDR5 RAM is set to run at a frequency of 1026 MHz on this specific card. It features 192 SPUs as well as 32 Texture Address Units and 24 ROPs.
Compare those specifications to the GeForce GTX 560 Ti, which features GPU clock speed of 822 MHz, and 1024 MB of GDDR5 memory set to run at 1002 MHz through a 256-bit bus. It also features 384 SPUs, 64 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 560 Ti should theoretically be much better than the GeForce GTX 550 Ti in general. (explain)
Texel RateThe GeForce GTX 560 Ti is much (more or less 83%) faster with regards to AF than the GeForce GTX 550 Ti. (explain)
Pixel RateThe GeForce GTX 560 Ti is a lot (more or less 22%) better at AA than the GeForce GTX 550 Ti, and also will be able to handle higher resolutions better. (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 transported over the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of 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.
