Compare any two graphics cards:
GeForce GTX 560 vs GeForce GTX 560 Ti
IntroThe GeForce GTX 560 features a core clock speed of 810 MHz and a GDDR5 memory frequency of 1001 MHz. It also makes use of a 256-bit memory bus, and makes use of a 40 nm design. It is comprised of 336 SPUs, 56 TAUs, and 32 Raster Operation Units.
Compare that to the GeForce GTX 560 Ti, which comes with a clock speed 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 is comprised of 384 SPUs, 64 Texture Address Units, and 32 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 560 Ti should perform a small bit faster than the GeForce GTX 560 in general. (explain)
Texel RateThe GeForce GTX 560 Ti is a small bit (about 16%) more effective at anisotropic filtering than the GeForce GTX 560. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTX 560 Ti is superior to the GeForce GTX 560, not by a very large margin though. (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 max amount of information (counted in MB per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
