Compare any two graphics cards:
GeForce GTX 460 vs GeForce GTX 550 Ti
IntroThe GeForce GTX 460 makes use of a 40 nm design. nVidia has clocked the core frequency at 675 MHz. The GDDR5 RAM works at a frequency of 900 MHz on this specific card. It features 336 SPUs as well as 56 Texture Address Units and 24 Rasterization Operator Units.
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 RAM works at a speed of 1026 MHz on this particular card. It features 192 SPUs along with 32 TAUs and 24 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 550 Ti will be 14% faster than the GeForce GTX 460 overall, because of its greater bandwidth. (explain)
Texel RateThe GeForce GTX 460 will be a lot (approximately 31%) faster with regards to texture filtering than the GeForce GTX 550 Ti. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 550 Ti is a better choice, by far. (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 information (in units of MB per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 can be processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
