Radeon RX 460 2GB		75 Watts
Radeon HD 5970		294 Watts
	Difference: 219 Watts (292%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 5970 should be 129% quicker than the Radeon RX 460 2GB in general, due to its greater data rate. (explain)

Radeon HD 5970		256000 MB/sec
Radeon RX 460 2GB		112000 MB/sec
	Difference: 144000 (129%)

Texel Rate

The Radeon HD 5970 should be much (approximately 280%) faster with regards to texture filtering than the Radeon RX 460 2GB. (explain)

Radeon HD 5970		232000 Mtexels/sec
Radeon RX 460 2GB		61040 Mtexels/sec
	Difference: 170960 (280%)

Pixel Rate

The Radeon HD 5970 will be quite a bit (about 432%) faster with regards to AA than the Radeon RX 460 2GB, and also should be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon HD 5970		92800 Mpixels/sec
Radeon RX 460 2GB		17440 Mpixels/sec
	Difference: 75360 (432%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total texture units 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 a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. 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 fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
