Compare any two graphics cards:
GeForce GTX 560 vs Geforce GTX 760
IntroThe GeForce GTX 560 features core speeds of 810 MHz on the GPU, and 1001 MHz on the 1024 MB of GDDR5 memory. It features 336 SPUs along with 56 Texture Address Units and 32 ROPs.
Compare that to the Geforce GTX 760, which has a clock frequency of 980 MHz and a GDDR5 memory frequency of 1502 MHz. It also uses a 256-bit memory bus, and uses a 28 nm design. It is comprised of 1152 SPUs, 96 Texture Address Units, and 32 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Geforce GTX 760 should in theory be a lot faster than the GeForce GTX 560 in general. (explain)
Texel RateThe Geforce GTX 760 should be quite a bit (about 107%) faster with regards to texture filtering than the GeForce GTX 560. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Geforce GTX 760 is the winner, by a large margin. (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 maximum amount of data (counted in MB per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
