Compare any two graphics cards:
GeForce GTX 550 Ti vs GeForce GTX 560 Ti
IntroThe GeForce GTX 550 Ti features clock speeds of 900 MHz on the GPU, and 1026 MHz on the 1024 MB of GDDR5 memory. It features 192 SPUs as well as 32 TAUs and 24 Rasterization Operator Units.
Compare all that to the GeForce GTX 560 Ti, which makes use of a 40 nm design. nVidia has set the core speed at 822 MHz. The GDDR5 RAM runs at a speed of 1002 MHz on this particular model. It features 384 SPUs along with 64 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 560 Ti will be 30% quicker than the GeForce GTX 550 Ti in general, due to its greater data rate. (explain)
Texel RateThe GeForce GTX 560 Ti will be a lot (approximately 83%) faster with regards to AF than the GeForce GTX 550 Ti. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTX 560 Ti is the winner, by a large margin. (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 maximum amount of information (counted in megabytes per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the 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 maximum number of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core 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 is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
