Compare any two graphics cards:
GeForce GTX 560 Ti vs GeForce GTX 650 Ti
IntroThe GeForce GTX 560 Ti comes with a clock speed of 822 MHz and a GDDR5 memory frequency of 1002 MHz. It also features a 256-bit bus, and makes use of a 40 nm design. It is comprised of 384 SPUs, 64 Texture Address Units, and 32 ROPs.
Compare those specs to the GeForce GTX 650 Ti, which comes with clock speeds of 928 MHz on the GPU, and 1350 MHz on the 1024 MB of GDDR5 RAM. It features 768 SPUs as well as 64 TAUs and 16 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 560 Ti, in theory, should be quite a bit faster than the GeForce GTX 650 Ti overall. (explain)
Texel RateThe GeForce GTX 650 Ti is a bit (approximately 13%) more effective at texture filtering than the GeForce GTX 560 Ti. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 560 Ti is superior to the GeForce GTX 650 Ti, and very much so. (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 max amount of data (measured in MB per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video 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 most pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
