GeForce 8800 Ultra		103680 MB/sec
	Difference: 8320 (8%)

Texel Rate

The Radeon RX 460 2GB is much (approximately 56%) faster with regards to texture filtering than the GeForce 8800 Ultra. (explain)

Radeon RX 460 2GB		61040 Mtexels/sec
GeForce 8800 Ultra		39168 Mtexels/sec
	Difference: 21872 (56%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 460 2GB is superior to the GeForce 8800 Ultra, though only just barely. (explain)

Radeon RX 460 2GB		17440 Mpixels/sec
GeForce 8800 Ultra		14688 Mpixels/sec
	Difference: 2752 (19%)

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: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The figure 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 outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
