Radeon HD 5570		43 Watts
Radeon RX 460 2GB		75 Watts
	Difference: 32 Watts (74%)

Memory Bandwidth

Theoretically, the Radeon RX 460 2GB should perform quite a bit faster than the Radeon HD 5570 in general. (explain)

Radeon RX 460 2GB		112000 MB/sec
Radeon HD 5570		28800 MB/sec
	Difference: 83200 (289%)

Texel Rate

The Radeon RX 460 2GB is much (approximately 370%) more effective at anisotropic filtering than the Radeon HD 5570. (explain)

Radeon RX 460 2GB		61040 Mtexels/sec
Radeon HD 5570		13000 Mtexels/sec
	Difference: 48040 (370%)

Pixel Rate

The Radeon RX 460 2GB should be quite a bit (more or less 235%) more effective at FSAA than the Radeon HD 5570, and also should be able to handle higher resolutions without slowing down too much. (explain)

Radeon RX 460 2GB		17440 Mpixels/sec
Radeon HD 5570		5200 Mpixels/sec
	Difference: 12240 (235%)

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 data (counted in megabytes per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs 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 fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
