GeForce 8800 GT 512MB		57600 MB/sec
	Difference: 153600 (267%)

Texel Rate

The Radeon RX 470 4GB will be a lot (more or less 253%) more effective at anisotropic filtering than the GeForce 8800 GT 512MB. (explain)

Radeon RX 470 4GB		118528 Mtexels/sec
GeForce 8800 GT 512MB		33600 Mtexels/sec
	Difference: 84928 (253%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 470 4GB is a better choice, by far. (explain)

Radeon RX 470 4GB		29632 Mpixels/sec
GeForce 8800 GT 512MB		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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (measured in megabytes per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
