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 frequency at 822 MHz. The GDDR5 RAM works at a frequency of 1002 MHz on this specific card. It features 384 SPUs as well as 64 Texture Address Units and 32 Rasterization Operator Units.
Compare all that to the GeForce GTX 570, which makes use of a 40 nm design. nVidia has clocked the core frequency at 732 MHz. The GDDR5 RAM runs at a frequency of 950 MHz on this specific model. It features 480 SPUs as well as 60 TAUs and 40 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 570, in theory, should perform a little bit faster than the GeForce GTX 560 Ti overall. (explain)
Texel RateThe GeForce GTX 560 Ti should be a bit (more or less 20%) more effective at texture filtering than the GeForce GTX 570. (explain)
Pixel RateThe GeForce GTX 570 is a small bit (about 11%) more effective at anti-aliasing than the GeForce GTX 560 Ti, and also should be capable of handling higher screen resolutions while still performing well. (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 over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's 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 amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs 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 output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
