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

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 560 Ti should perform just a bit faster than the GeForce GTX 275 overall. (explain)
Texel RateThe GeForce GTX 560 Ti will be just a bit (approximately 4%) better at AF than the GeForce GTX 275. (explain)
Pixel RateThe GeForce GTX 560 Ti should be a lot (about 48%) better at FSAA than the GeForce GTX 275, and also should be capable of handling higher resolutions without losing too much performance. (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 max amount of information (measured in megabytes per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write 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 the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
