Compare any two graphics cards:
GeForce GTX 280 vs GeForce GTX 560 Ti
IntroThe GeForce GTX 280 makes use of a 65 nm design. nVidia has clocked the core speed at 602 MHz. The GDDR3 RAM is set to run at a speed of 1107 MHz on this particular model. It features 240 SPUs along with 80 Texture Address Units and 32 Rasterization Operator Units.
Compare those specs to the GeForce GTX 560 Ti, which comes with a core clock frequency of 822 MHz and a GDDR5 memory speed of 1002 MHz. It also features a 256-bit memory bus, and makes use of a 40 nm design. It features 384 SPUs, 64 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 280 will be 10% quicker than the GeForce GTX 560 Ti in general, because of its higher bandwidth. (explain)
Texel RateThe GeForce GTX 560 Ti will be a little bit (more or less 9%) more effective at texture 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 superior to the GeForce GTX 280, 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: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 texture map elements (texels) that are applied per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the graphics 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 maximum number of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core 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 lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
