Compare any two graphics cards:
GeForce GTX 560 vs Geforce GTX 760
IntroThe GeForce GTX 560 has a GPU clock speed of 810 MHz, and the 1024 MB of GDDR5 memory is set to run at 1001 MHz through a 256-bit bus. It also is made up of 336 SPUs, 56 Texture Address Units, and 32 Raster Operation Units.
Compare that to the Geforce GTX 760, which has a clock speed of 980 MHz and a GDDR5 memory frequency of 1502 MHz. It also features a 256-bit memory bus, and uses a 28 nm design. It is comprised of 1152 SPUs, 96 TAUs, and 32 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the Geforce GTX 760 should perform much faster than the GeForce GTX 560 overall. (explain)
Texel RateThe Geforce GTX 760 should be a lot (approximately 107%) more effective at AF than the GeForce GTX 560. (explain)
Pixel RateThe Geforce GTX 760 will be quite a bit (more or less 21%) more effective at full screen anti-aliasing than the GeForce GTX 560, and 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: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher 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 maximum amount of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called 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 ability to reach the max fill rate.
