GeForce GTX 460 (OEM) vs Radeon RX 470

Intro

Compare all of that to the Radeon RX 470, which has a GPU core clock speed of 926 MHz, and 8192 MB of GDDR5 memory set to run at 1650 MHz through a 256-bit bus. It also features 2048 Stream Processors, 128 TAUs, and 32 Raster Operation Units.

Texel Rate

The Radeon RX 470 will be a lot (about 226%) better at texture filtering than the GeForce GTX 460 (OEM). (explain)

Radeon RX 470		118528 Mtexels/sec
GeForce GTX 460 (OEM)		36400 Mtexels/sec
	Difference: 82128 (226%)

Pixel Rate

The Radeon RX 470 is a lot (approximately 42%) faster with regards to AA than the GeForce GTX 460 (OEM), and also should be able to handle higher resolutions while still performing well. (explain)

Radeon RX 470		29632 Mpixels/sec
GeForce GTX 460 (OEM)		20800 Mpixels/sec
	Difference: 8832 (42%)

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 information (in units of megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory per 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 - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
