Compare any two graphics cards:
GeForce GTX 280 vs GeForce GTX 550 Ti
IntroThe GeForce GTX 280 has a core clock frequency of 602 MHz and a GDDR3 memory frequency of 1107 MHz. It also makes use of a 512-bit memory bus, and uses a 65 nm design. It features 240 SPUs, 80 TAUs, and 32 ROPs.
Compare that to the GeForce GTX 550 Ti, which features a clock speed of 900 MHz and a GDDR5 memory speed of 1026 MHz. It also uses a 192-bit bus, and uses a 40 nm design. It is made up of 192 SPUs, 32 TAUs, and 24 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 280, in theory, should be quite a bit faster than the GeForce GTX 550 Ti in general. (explain)
Texel RateThe GeForce GTX 280 should be much (about 67%) better at AF than the GeForce GTX 550 Ti. (explain)
Pixel RateThe GeForce GTX 550 Ti should be a bit (more or less 12%) faster with regards to AA than the GeForce GTX 280, and also should be able to handle higher screen resolutions more effectively. (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 largest amount of information (measured in megabytes per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is calculated 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 per second.
Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
