Compare any two graphics cards:
GeForce GTX 550 Ti vs GeForce GTX 560 Ti
IntroThe GeForce GTX 550 Ti comes with a GPU core speed of 900 MHz, and the 1024 MB of GDDR5 RAM runs at 1026 MHz through a 192-bit bus. It also features 192 SPUs, 32 TAUs, and 24 ROPs.
Compare that to the GeForce GTX 560 Ti, which features GPU clock speed of 822 MHz, and 1024 MB of GDDR5 RAM running at 1002 MHz through a 256-bit bus. It also is comprised of 384 Stream Processors, 64 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 560 Ti should be 30% quicker than the GeForce GTX 550 Ti in general, due to its higher data rate. (explain)
Texel RateThe GeForce GTX 560 Ti should be quite a bit (more or less 83%) faster with regards to anisotropic filtering than the GeForce GTX 550 Ti. (explain)
Pixel RateThe GeForce GTX 560 Ti should be a lot (about 22%) faster with regards to FSAA than the GeForce GTX 550 Ti, and should be able to handle higher screen resolutions while still performing well. (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 max amount of information (measured in megabytes per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling 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 could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core 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 fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
