Compare any two graphics cards:
GeForce GTX 460 1GB vs GeForce GTX 550 Ti
IntroThe GeForce GTX 460 1GB makes use of a 40 nm design. nVidia has clocked the core speed at 675 MHz. The GDDR5 RAM is set to run at a frequency of 900 MHz on this particular card. It features 336 SPUs as well as 56 TAUs and 32 Rasterization Operator Units.
Compare all of that to the GeForce GTX 550 Ti, which features a core clock speed of 900 MHz and a GDDR5 memory frequency of 1026 MHz. It also uses a 192-bit memory bus, and makes use of a 40 nm design. It is made up of 192 SPUs, 32 Texture Address Units, and 24 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 460 1GB should perform a little bit faster than the GeForce GTX 550 Ti in general. (explain)
Texel RateThe GeForce GTX 460 1GB is quite a bit (about 31%) more effective at anisotropic filtering than the GeForce GTX 550 Ti. (explain)
Pixel RateBoth cards have the exact same pixel rate, so theoretically they should be equally good at at FSAA, and be able to handle the same screen resolutions. (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 past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units of the card 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 in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate 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 outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
