Compare any two graphics cards:
GeForce GTX 560 vs GeForce GTX 560 Ti
IntroThe GeForce GTX 560 makes use of a 40 nm design. nVidia has clocked the core frequency at 810 MHz. The GDDR5 RAM works at a speed of 1001 MHz on this model. It features 336 SPUs as well as 56 TAUs and 32 Rasterization Operator Units.
Compare those specifications to the GeForce GTX 560 Ti, which comes with core clock speeds of 822 MHz on the GPU, and 1002 MHz on the 1024 MB of GDDR5 RAM. It features 384 SPUs as well as 64 TAUs and 32 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 560 Ti should theoretically be a small bit better than the GeForce GTX 560 overall. (explain)
Texel RateThe GeForce GTX 560 Ti will be a little bit (more or less 16%) more effective at texture filtering than the GeForce GTX 560. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTX 560 Ti is superior to the GeForce GTX 560, though not by far. (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 maximum amount of information (measured in megabytes per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the graphics 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 most pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
