The GeForce GTX 1060 is much (more or less 144%) faster with regards to anisotropic filtering than the GeForce GTX 580 3GB. (explain)

GeForce GTX 1060		120480 Mtexels/sec
GeForce GTX 580 3GB		49408 Mtexels/sec
	Difference: 71072 (144%)

Pixel Rate

The GeForce GTX 1060 will be quite a bit (approximately 95%) better at anti-aliasing than the GeForce GTX 580 3GB, and will be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 1060		72288 Mpixels/sec
GeForce GTX 580 3GB		37056 Mpixels/sec
	Difference: 35232 (95%)

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.

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics 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 that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
