Compare any two graphics cards:
GeForce GTX 560 Ti vs Geforce GTX 760
IntroThe GeForce GTX 560 Ti features a GPU core clock speed of 822 MHz, and the 1024 MB of GDDR5 RAM is set to run at 1002 MHz through a 256-bit bus. It also features 384 SPUs, 64 TAUs, and 32 ROPs.
Compare that to the Geforce GTX 760, which makes use of a 28 nm design. nVidia has set the core frequency at 980 MHz. The GDDR5 memory is set to run at a frequency of 1502 MHz on this particular model. It features 1152 SPUs as well as 96 TAUs and 32 Rasterization Operator Units.
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
The Geforce GTX 760 should theoretically perform a lot faster than the GeForce GTX 560 Ti in general. (explain)
Texel RateThe Geforce GTX 760 will be a lot (more or less 79%) better at anisotropic filtering than the GeForce GTX 560 Ti. (explain)
Pixel RateThe Geforce GTX 760 will be a small bit (approximately 19%) faster with regards to anti-aliasing than the GeForce GTX 560 Ti, and capable of handling higher 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: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 are processed per second. This is calculated 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
