Compare any two graphics cards:
GeForce GTX 560 Ti vs GeForce GTX 650 Ti
IntroThe GeForce GTX 560 Ti makes use of a 40 nm design. nVidia has clocked the core speed at 822 MHz. The GDDR5 RAM is set to run at a speed of 1002 MHz on this specific card. It features 384 SPUs as well as 64 Texture Address Units and 32 ROPs.
Compare those specifications to the GeForce GTX 650 Ti, which uses a 28 nm design. nVidia has clocked the core frequency at 928 MHz. The GDDR5 RAM is set to run at a frequency of 1350 MHz on this specific model. It features 768 SPUs along with 64 TAUs and 16 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 560 Ti should in theory be a lot faster than the GeForce GTX 650 Ti overall. (explain)
Texel RateThe GeForce GTX 650 Ti should be just a bit (approximately 13%) better at texture filtering than the GeForce GTX 560 Ti. (explain)
Pixel RateThe GeForce GTX 560 Ti is a lot (about 77%) faster with regards to full screen anti-aliasing than the GeForce GTX 650 Ti, and also able to handle higher resolutions without losing too much performance. (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 largest amount of information (in units of MB per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can 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 core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
