Compare any two graphics cards:
GeForce GTX 460 2GB vs GeForce GTX 560
IntroThe GeForce GTX 460 2GB uses a 40 nm design. nVidia has clocked the core speed at 675 MHz. The GDDR5 RAM is set to run at a frequency of 900 MHz on this specific model. It features 336 SPUs as well as 56 TAUs and 32 Rasterization Operator Units.Compare those specs to the GeForce GTX 560, which comes with GPU core speed of 810 MHz, and 1024 MB of GDDR5 RAM set to run at 1001 MHz through a 256-bit bus. It also is made up of 336 SPUs, 56 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce GTX 560 should be a small bit faster than the GeForce GTX 460 2GB overall. (explain)
Texel RateThe GeForce GTX 560 should be just a bit (approximately 20%) better at anisotropic filtering than the GeForce GTX 460 2GB. (explain)
Pixel RateThe GeForce GTX 560 will be a small bit (about 20%) more effective at AA than the GeForce GTX 460 2GB, and should be capable of handling higher resolutions more effectively. (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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
