Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 470 4GB		120 Watts
GeForce GTX 480		250 Watts
	Difference: 130 Watts (108%)

Memory Bandwidth

Performance-wise, the Radeon RX 470 4GB should in theory be just a bit superior to the GeForce GTX 480 overall. (explain)

Radeon RX 470 4GB		211200 MB/sec
GeForce GTX 480		177408 MB/sec
	Difference: 33792 (19%)

Texel Rate

The Radeon RX 470 4GB is a lot (more or less 182%) faster with regards to anisotropic filtering than the GeForce GTX 480. (explain)

Radeon RX 470 4GB		118528 Mtexels/sec
GeForce GTX 480		42000 Mtexels/sec
	Difference: 76528 (182%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 480 is a better choice, though not by far. (explain)

GeForce GTX 480		33600 Mpixels/sec
Radeon RX 470 4GB		29632 Mpixels/sec
	Difference: 3968 (13%)

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 data (counted in megabytes per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 in one second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
