Compare any two graphics cards:
GeForce GTX 550 Ti vs GeForce GTX 560
IntroThe GeForce GTX 550 Ti uses a 40 nm design. nVidia has set the core frequency at 900 MHz. The GDDR5 memory runs at a frequency of 1026 MHz on this model. It features 192 SPUs along with 32 TAUs and 24 Rasterization Operator Units.
Compare all that to the GeForce GTX 560, which comes with a clock frequency of 810 MHz and a GDDR5 memory frequency of 1001 MHz. It also features a 256-bit bus, and makes use of a 40 nm design. It is comprised of 336 SPUs, 56 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 560 should perform quite a bit faster than the GeForce GTX 550 Ti in general. (explain)
Texel RateThe GeForce GTX 560 will be a lot (more or less 58%) better at texture filtering than the GeForce GTX 550 Ti. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GTX 560 is superior to the GeForce GTX 550 Ti, though not 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: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 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 better the texel rate, the better the video 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 most pixels that the graphics card could possibly record 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 clock 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 fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
