Compare any two graphics cards:
GeForce GTX 550 Ti vs GeForce GTX 560 Ti
IntroThe GeForce GTX 550 Ti has clock speeds of 900 MHz on the GPU, and 1026 MHz on the 1024 MB of GDDR5 RAM. It features 192 SPUs along with 32 Texture Address Units and 24 Rasterization Operator Units.
Compare those specs to the GeForce GTX 560 Ti, which features GPU core speed of 822 MHz, and 1024 MB of GDDR5 RAM set to run at 1002 MHz through a 256-bit bus. It also features 384 SPUs, 64 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 560 Ti should perform a lot faster than the GeForce GTX 550 Ti overall. (explain)
Texel RateThe GeForce GTX 560 Ti will be much (approximately 83%) better at texture filtering than the GeForce GTX 550 Ti. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTX 560 Ti is a better choice, by far. (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 data (counted in MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. 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 bandwidth is, the lower the ability to get to the maximum fill rate.
