Compare any two graphics cards:
GeForce GTX 470 vs GeForce GTX 550 Ti
IntroThe GeForce GTX 470 uses a 40 nm design. nVidia has set the core speed at 607 MHz. The GDDR5 memory works at a speed of 837 MHz on this specific model. It features 448 SPUs along with 56 TAUs and 40 Rasterization Operator Units.
Compare all that 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 is set to run at a speed of 1026 MHz on this particular card. It features 192 SPUs along with 32 Texture Address Units and 24 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 470 should theoretically be quite a bit faster than the GeForce GTX 550 Ti in general. (explain)
Texel RateThe GeForce GTX 470 will be a bit (approximately 18%) better at 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 470 is superior to the GeForce GTX 550 Ti, but it probably won't make a huge difference. (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 (measured in MB per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units by the core clock 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 in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
