Compare any two graphics cards:
GeForce GTX 280 vs GeForce GTX 560 Ti
IntroThe GeForce GTX 280 comes with a GPU core clock speed of 602 MHz, and the 1024 MB of GDDR3 RAM runs at 1107 MHz through a 512-bit bus. It also is comprised of 240 Stream Processors, 80 Texture Address Units, and 32 Raster Operation Units.
Compare all of that to the GeForce GTX 560 Ti, which comes with core speeds of 822 MHz on the GPU, and 1002 MHz on the 1024 MB of GDDR5 memory. It features 384 SPUs as well as 64 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 280 should in theory be a little bit better than the GeForce GTX 560 Ti in general. (explain)
Texel RateThe GeForce GTX 560 Ti should be a bit (about 9%) faster with regards to anisotropic filtering than the GeForce GTX 280. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 560 Ti is a better choice, and very much so. (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 (counted in MB per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher 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 one second.
Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core 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 also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
