Compare any two graphics cards:
GeForce GTX 460 1GB vs GeForce GTX 550 Ti
IntroThe GeForce GTX 460 1GB uses a 40 nm design. nVidia has set the core speed at 675 MHz. The GDDR5 memory works at a frequency of 900 MHz on this specific model. It features 336 SPUs along with 56 Texture Address Units and 32 ROPs.
Compare all that to the GeForce GTX 550 Ti, which makes use of a 40 nm design. nVidia has set the core frequency at 900 MHz. The GDDR5 memory works at a frequency of 1026 MHz on this particular model. It features 192 SPUs as well as 32 TAUs and 24 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 460 1GB should theoretically be a small bit superior to the GeForce GTX 550 Ti overall. (explain)
Texel RateThe GeForce GTX 460 1GB will be much (about 31%) more effective at AF than the GeForce GTX 550 Ti. (explain)
Pixel RateBoth cards have exactly the same pixel rate, so theoretically they should perform equally good at at anti-aliasing, and be capable of handling 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: Memory bandwidth is the max amount of data (in units of MB per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 can be processed per second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
