Radeon RX 460 2GB		75 Watts
	Difference: 25 Watts (50%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 460 2GB should be 289% quicker than the Radeon HD 6570 (OEM) 1GB in general, because of its higher data rate. (explain)

Radeon RX 460 2GB		112000 MB/sec
Radeon HD 6570 (OEM) 1GB		28800 MB/sec
	Difference: 83200 (289%)

Texel Rate

The Radeon RX 460 2GB should be quite a bit (more or less 291%) more effective at AF than the Radeon HD 6570 (OEM) 1GB. (explain)

Radeon RX 460 2GB		61040 Mtexels/sec
Radeon HD 6570 (OEM) 1GB		15600 Mtexels/sec
	Difference: 45440 (291%)

Pixel Rate

The Radeon RX 460 2GB is a lot (more or less 235%) more effective at full screen anti-aliasing than the Radeon HD 6570 (OEM) 1GB, and also capable of handling higher resolutions without losing too much performance. (explain)

Radeon RX 460 2GB		17440 Mpixels/sec
Radeon HD 6570 (OEM) 1GB		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: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
