Compare any two graphics cards:
GeForce GTX 560 vs Geforce GTX 760
IntroThe GeForce GTX 560 uses a 40 nm design. nVidia has set the core speed at 810 MHz. The GDDR5 RAM works at a frequency of 1001 MHz on this specific model. It features 336 SPUs as well as 56 Texture Address Units and 32 Rasterization Operator Units.
Compare all that to the Geforce GTX 760, which features GPU core speed of 980 MHz, and 2048 MB of GDDR5 memory running at 1502 MHz through a 256-bit bus. It also is comprised of 1152 SPUs, 96 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Geforce GTX 760 should in theory be a lot faster than the GeForce GTX 560 overall. (explain)
Texel RateThe Geforce GTX 760 should be quite a bit (more or less 107%) better at anisotropic filtering than the GeForce GTX 560. (explain)
Pixel RateThe Geforce GTX 760 will be a lot (approximately 21%) faster with regards to AA than the GeForce GTX 560, and also will 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.
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 megabytes per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
