The Radeon RX 570 should be much (more or less 345%) faster with regards to texture filtering than the GeForce 8800 GT 512MB. (explain)

Radeon RX 570		149504 Mtexels/sec
GeForce 8800 GT 512MB		33600 Mtexels/sec
	Difference: 115904 (345%)

Pixel Rate

The Radeon RX 570 is much (more or less 289%) better at full screen anti-aliasing than the GeForce 8800 GT 512MB, and also should be capable of handling higher resolutions without losing too much performance. (explain)

Radeon RX 570		37376 Mpixels/sec
GeForce 8800 GT 512MB		9600 Mpixels/sec
	Difference: 27776 (289%)

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 maximum amount of information (in units of MB per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
