GeForce GTX 260 216SP 55 nm		171 Watts
	Difference: 51 Watts (43%)

Memory Bandwidth

As far as performance goes, the Radeon RX 470 4GB should in theory be quite a bit superior to the GeForce GTX 260 216SP 55 nm in general. (explain)

Radeon RX 470 4GB		211200 MB/sec
GeForce GTX 260 216SP 55 nm		111888 MB/sec
	Difference: 99312 (89%)

Texel Rate

The Radeon RX 470 4GB is quite a bit (about 186%) better at AF than the GeForce GTX 260 216SP 55 nm. (explain)

Radeon RX 470 4GB		118528 Mtexels/sec
GeForce GTX 260 216SP 55 nm		41472 Mtexels/sec
	Difference: 77056 (186%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 470 4GB is superior to the GeForce GTX 260 216SP 55 nm, and very much so. (explain)

Radeon RX 470 4GB		29632 Mpixels/sec
GeForce GTX 260 216SP 55 nm		16128 Mpixels/sec
	Difference: 13504 (84%)

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 max amount of information (measured in megabytes per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling 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 record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
