Compare any two graphics cards:
GeForce GTX 460 vs GeForce GTX 560 Ti
IntroThe GeForce GTX 460 uses a 40 nm design. nVidia has set the core frequency at 675 MHz. The GDDR5 RAM works at a speed of 900 MHz on this model. It features 336 SPUs along with 56 Texture Address Units and 24 ROPs.
Compare that to the GeForce GTX 560 Ti, which comes with GPU clock speed of 822 MHz, and 1024 MB of GDDR5 RAM running at 1002 MHz through a 256-bit bus. It also is made up of 384 Stream Processors, 64 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 560 Ti should in theory perform a lot faster than the GeForce GTX 460 overall. (explain)
Texel RateThe GeForce GTX 560 Ti will be much (approximately 39%) more effective at AF than the GeForce GTX 460. (explain)
Pixel RateIf using a high resolution 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: Bandwidth is the max amount of information (in units of megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 can be processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
