Compare any two graphics cards:
GeForce GTX 1060 3GB vs GeForce GTX 580 3GB
IntroThe GeForce GTX 1060 3GB uses a 16 nm design. nVidia has clocked the core frequency at 1506 MHz. The GDDR5 RAM is set to run at a speed of 2000 MHz on this specific card. It features 1152 SPUs as well as 72 Texture Address Units and 48 ROPs.
Compare all of that to the GeForce GTX 580 3GB, which comes with a core clock speed of 772 MHz and a GDDR5 memory frequency of 1002 MHz. It also uses a 384-bit memory bus, and uses a 40 nm design. It is made up of 512 SPUs, 64 Texture Address Units, and 48 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 1060 3GB should be a little bit faster than the GeForce GTX 580 3GB in general. (explain)
Texel RateThe GeForce GTX 1060 3GB is quite a bit (approximately 119%) faster with regards to AF than the GeForce GTX 580 3GB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 1060 3GB is a better choice, 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 max amount of information (counted in megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock 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 applied per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
