Compare any two graphics cards:
GeForce GTS 450 vs GeForce GTX 550 Ti
IntroThe GeForce GTS 450 uses a 40 nm design. nVidia has clocked the core speed at 783 MHz. The GDDR5 RAM is set to run at a frequency of 902 MHz on this card. It features 192 SPUs along with 32 Texture Address Units and 16 ROPs.
Compare those specifications to the GeForce GTX 550 Ti, which makes use of a 40 nm design. nVidia has clocked the core speed at 900 MHz. The GDDR5 memory runs at a speed of 1026 MHz on this specific model. It features 192 SPUs as well as 32 Texture Address Units and 24 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 550 Ti should in theory be a lot faster than the GeForce GTS 450 in general. (explain)
Texel RateThe GeForce GTX 550 Ti should be a little bit (approximately 15%) more effective at AF than the GeForce GTS 450. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 550 Ti is a better choice, by a large margin. (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 information (measured in MB per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video 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 maximum number of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. 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 fill 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.
