Compare any two graphics cards:
GeForce GTX 460 vs GeForce GTX 550 Ti
IntroThe GeForce GTX 460 uses a 40 nm design. nVidia has clocked the core speed at 675 MHz. The GDDR5 RAM runs at a speed of 900 MHz on this particular card. It features 336 SPUs as well as 56 TAUs and 24 ROPs.
Compare those specs to the GeForce GTX 550 Ti, which uses a 40 nm design. nVidia has set the core speed at 900 MHz. The GDDR5 memory works at a speed of 1026 MHz on this particular card. It features 192 SPUs as well as 32 Texture Address Units and 24 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 550 Ti should be a bit faster than the GeForce GTX 460 in general. (explain)
Texel RateThe GeForce GTX 460 will be a lot (about 31%) better at AF than the GeForce GTX 550 Ti. (explain)
Pixel RateThe GeForce GTX 550 Ti should be much (about 33%) better at anti-aliasing than the GeForce GTX 460, and also should be capable of handling higher 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.
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 information (counted in 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 speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
