Texel Rate

The Radeon RX 460 2GB should be quite a bit (approximately 56%) more effective at AF than the GeForce 8800 Ultra. (explain)

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

Pixel Rate

The Radeon RX 460 2GB will be a bit (approximately 19%) more effective at AA than the GeForce 8800 Ultra, and also able to handle higher screen resolutions without losing too much performance. (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 maximum amount of data (measured in MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 number of texture map elements (texels) that can be processed per second. This number is calculated 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 graphics 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 maximum amount of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out 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 filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
