GeForce GTX 470 vs Radeon RX 460 2GB

Intro

Compare all that to the Radeon RX 460 2GB, which comes with a clock speed of 1090 MHz and a GDDR5 memory speed of 1750 MHz. It also makes use of a 128-bit memory bus, and makes use of a 14 nm design. It is comprised of 896 SPUs, 56 Texture Address Units, and 16 ROPs.

GeForce GTX 470		33992 Mtexels/sec
	Difference: 27048 (80%)

Pixel Rate

The GeForce GTX 470 should be much (about 39%) faster with regards to AA than the Radeon RX 460 2GB, and will be capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 470		24280 Mpixels/sec
Radeon RX 460 2GB		17440 Mpixels/sec
	Difference: 6840 (39%)

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 maximum amount of information (in units of megabytes per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
