Compare any two graphics cards:
GeForce GTX 560 vs GeForce GTX 560 Ti
IntroThe GeForce GTX 560 features a GPU core speed of 810 MHz, and the 1024 MB of GDDR5 RAM is 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 Raster Operation Units.
Compare those specifications to the GeForce GTX 560 Ti, which comes with a core clock speed of 822 MHz and a GDDR5 memory speed of 1002 MHz. It also makes use of a 256-bit bus, and makes use of a 40 nm design. It features 384 SPUs, 64 TAUs, and 32 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 560 Ti should theoretically perform just a bit faster than the GeForce GTX 560 in general. (explain)
Texel RateThe GeForce GTX 560 Ti will be a bit (approximately 16%) better at AF than the GeForce GTX 560. (explain)
Pixel RateThe GeForce GTX 560 Ti will be a bit (approximately 1%) more effective at anti-aliasing than the GeForce GTX 560, and also able to handle higher screen resolutions better. (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 largest amount of information (measured in megabytes per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better 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 maximum amount of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
