Compare any two graphics cards:
GeForce GTX 550 Ti vs GeForce GTX 560
IntroThe GeForce GTX 550 Ti features a clock frequency of 900 MHz and a GDDR5 memory speed of 1026 MHz. It also makes use of a 192-bit memory bus, and makes use of a 40 nm design. It is comprised of 192 SPUs, 32 TAUs, and 24 Raster Operation Units.
Compare all that to the GeForce GTX 560, which has GPU clock speed of 810 MHz, and 1024 MB of GDDR5 memory running at 1001 MHz through a 256-bit bus. It also is comprised of 336 Stream Processors, 56 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 560 should theoretically perform much 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 anisotropic filtering than the GeForce GTX 550 Ti. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 560 is superior to the GeForce GTX 550 Ti, but it probably won't make a huge difference. (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 (in units of megabytes per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number 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 output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
