Compare any two graphics cards:
GeForce GTX 280 vs GeForce GTX 550 Ti
IntroThe GeForce GTX 280 features core speeds of 602 MHz on the GPU, and 1107 MHz on the 1024 MB of GDDR3 memory. It features 240 SPUs as well as 80 Texture Address Units and 32 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 speed at 900 MHz. The GDDR5 RAM is set to run at a frequency of 1026 MHz on this specific model. It features 192 SPUs along with 32 TAUs and 24 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 280 should in theory be a lot superior to the GeForce GTX 550 Ti in general. (explain)
Texel RateThe GeForce GTX 280 will be much (about 67%) more effective at texture filtering than the GeForce GTX 550 Ti. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 550 Ti is the winner, though not 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 largest amount of data (counted in MB per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better 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 can be applied in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the maximum amount of 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 number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
