Compare any two graphics cards:
GeForce GTX 560 Ti vs GeForce GTX 570
IntroThe GeForce GTX 560 Ti uses a 40 nm design. nVidia has set the core speed at 822 MHz. The GDDR5 memory works at a frequency of 1002 MHz on this specific model. It features 384 SPUs as well as 64 TAUs and 32 Rasterization Operator Units.
Compare those specs to the GeForce GTX 570, which comes with a GPU core clock speed of 732 MHz, and 1280 MB of GDDR5 RAM set to run at 950 MHz through a 320-bit bus. It also is comprised of 480 Stream Processors, 60 Texture Address Units, and 40 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 570 should in theory perform a bit faster than the GeForce GTX 560 Ti in general. (explain)
Texel RateThe GeForce GTX 560 Ti will be a small bit (about 20%) faster with regards to texture 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 max amount of information (measured in megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 processed per second. This number is worked out by multiplying the total number of texture units by the core clock 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 applied in one second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in one 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 - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
