Radeon RX 470 4GB		211200 MB/sec
GeForce 8800 GT 1GB		57600 MB/sec
	Difference: 153600 (267%)

Texel Rate

The Radeon RX 470 4GB will be a lot (about 253%) faster with regards to anisotropic filtering than the GeForce 8800 GT 1GB. (explain)

Radeon RX 470 4GB		118528 Mtexels/sec
GeForce 8800 GT 1GB		33600 Mtexels/sec
	Difference: 84928 (253%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 470 4GB is the winner, and very much so. (explain)

Radeon RX 470 4GB		29632 Mpixels/sec
GeForce 8800 GT 1GB		9600 Mpixels/sec
	Difference: 20032 (209%)

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 (in units of megabytes per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 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 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 that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. 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 rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
