GeForce 8800 GT 1GB		57600 MB/sec
	Difference: 204544 (355%)

Texel Rate

The Radeon RX 580 is quite a bit (about 439%) faster with regards to anisotropic filtering than the GeForce 8800 GT 1GB. (explain)

Radeon RX 580		181008 Mtexels/sec
GeForce 8800 GT 1GB		33600 Mtexels/sec
	Difference: 147408 (439%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 580 is the winner, by a large margin. (explain)

Radeon RX 580		40224 Mpixels/sec
GeForce 8800 GT 1GB		9600 Mpixels/sec
	Difference: 30624 (319%)

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 largest amount of information (measured in megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 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, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip 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 clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
