Compare any two graphics cards:
GeForce GTX 275 vs GeForce GTX 560 Ti
IntroThe GeForce GTX 275 has a clock speed of 633 MHz and a GDDR3 memory speed of 1134 MHz. It also features a 448-bit bus, and uses a 55 nm design. It is made up of 240 SPUs, 80 TAUs, and 28 ROPs.
Compare all that to the GeForce GTX 560 Ti, which has a core clock frequency of 822 MHz and a GDDR5 memory speed of 1002 MHz. It also uses a 256-bit memory bus, and uses a 40 nm design. It features 384 SPUs, 64 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 560 Ti should in theory be a bit superior to the GeForce GTX 275 in general. (explain)
Texel RateThe GeForce GTX 560 Ti will be a little bit (approximately 4%) better at AF than the GeForce GTX 275. (explain)
Pixel RateThe GeForce GTX 560 Ti should be much (more or less 48%) better at full screen anti-aliasing than the GeForce GTX 275, and also will be capable of handling higher screen resolutions without slowing down too much. (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 maximum amount of data (counted in megabytes per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total texture units by the core clock 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 processed per second.
Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock 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 lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
