Compare any two graphics cards:
GeForce GTX 560 Ti vs GeForce GTX 570
IntroThe GeForce GTX 560 Ti comes with a GPU core clock speed of 822 MHz, and the 1024 MB of GDDR5 memory runs at 1002 MHz through a 256-bit bus. It also is made up of 384 SPUs, 64 TAUs, and 32 ROPs.
Compare those specs to the GeForce GTX 570, which comes with GPU clock speed of 732 MHz, and 1280 MB of GDDR5 memory set to run at 950 MHz through a 320-bit bus. It also is made up of 480 Stream Processors, 60 TAUs, and 40 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 570 should in theory be a bit superior to the GeForce GTX 560 Ti in general. (explain)
Texel RateThe GeForce GTX 560 Ti is just a bit (approximately 20%) faster with regards to texture filtering than the GeForce GTX 570. (explain)
Pixel RateThe GeForce GTX 570 should be a small bit (about 11%) faster with regards to anti-aliasing than the GeForce GTX 560 Ti, and should be able to handle higher screen resolutions without slowing down too much. (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 maximum amount of information (counted in MB per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output 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 ability to get to the maximum fill rate.
