Compare any two graphics cards:
GeForce GTX 560 Ti vs GeForce GTX 570
IntroThe GeForce GTX 560 Ti has a GPU core clock speed of 822 MHz, and the 1024 MB of GDDR5 memory is set to run at 1002 MHz through a 256-bit bus. It also is made up of 384 SPUs, 64 TAUs, and 32 Raster Operation Units.
Compare those specs to the GeForce GTX 570, which features a core clock frequency of 732 MHz and a GDDR5 memory frequency of 950 MHz. It also uses a 320-bit bus, and uses a 40 nm design. It is made up of 480 SPUs, 60 Texture Address Units, and 40 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the GeForce GTX 570 should be a little bit faster than the GeForce GTX 560 Ti in general. (explain)
Texel RateThe GeForce GTX 560 Ti is a small bit (approximately 20%) faster with regards to anisotropic filtering than the GeForce GTX 570. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GTX 570 is superior to the GeForce GTX 560 Ti, though only just barely. (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 information (counted in MB per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
