Compare any two graphics cards:
GeForce GTX 560 vs Geforce GTX 760
IntroThe GeForce GTX 560 uses a 40 nm design. nVidia has clocked the core frequency at 810 MHz. The GDDR5 RAM works at a frequency of 1001 MHz on this particular card. It features 336 SPUs along with 56 Texture Address Units and 32 Rasterization Operator Units.
Compare those specs to the Geforce GTX 760, which uses a 28 nm design. nVidia has set the core frequency at 980 MHz. The GDDR5 memory works at a frequency of 1502 MHz on this specific card. It features 1152 SPUs along with 96 Texture Address Units and 32 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Geforce GTX 760 should theoretically perform quite a bit faster than the GeForce GTX 560 overall. (explain)
Texel RateThe Geforce GTX 760 should be a lot (more or less 107%) more effective at texture filtering than the GeForce GTX 560. (explain)
Pixel RateThe Geforce GTX 760 will be a lot (more or less 21%) more effective at anti-aliasing than the GeForce GTX 560, 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: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
