Compare any two graphics cards:
GeForce GTX 280 vs GeForce GTX 550 Ti
IntroThe GeForce GTX 280 uses a 65 nm design. nVidia has set the core speed at 602 MHz. The GDDR3 memory works at a frequency of 1107 MHz on this model. It features 240 SPUs as well as 80 TAUs and 32 ROPs.
Compare all of that to the GeForce GTX 550 Ti, which has GPU core speed of 900 MHz, and 1024 MB of GDDR5 RAM set to run at 1026 MHz through a 192-bit bus. It also is made up of 192 Stream Processors, 32 Texture Address Units, and 24 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 280 should theoretically be a lot better than the GeForce GTX 550 Ti overall. (explain)
Texel RateThe GeForce GTX 280 will be a lot (about 67%) more effective at AF than the GeForce GTX 550 Ti. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 550 Ti is superior to the GeForce GTX 280, but only just. (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.
Price ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Bandwidth is the max amount of information (in units of megabytes per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video 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 amount of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's 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 is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
