Compare any two graphics cards:
GeForce GTX 550 Ti vs GeForce GTX 560
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 particular card. It features 192 SPUs along with 32 TAUs and 24 Rasterization Operator Units.
Compare all of that to the GeForce GTX 560, which uses a 40 nm design. nVidia has set the core frequency at 810 MHz. The GDDR5 memory is set to run at a speed of 1001 MHz on this card. It features 336 SPUs along with 56 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 560 should in theory perform a lot faster than the GeForce GTX 550 Ti in general. (explain)
Texel RateThe GeForce GTX 560 will be quite a bit (more or less 58%) better at texture filtering than the GeForce GTX 550 Ti. (explain)
Pixel RateThe GeForce GTX 560 is just a bit (more or less 20%) better at FSAA than the GeForce GTX 550 Ti, and also 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.
Price ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
