Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon RX 460 2GB should in theory perform a small bit faster than the Radeon R9 M385X overall. (explain)

Radeon RX 460 2GB		112000 MB/sec
Radeon R9 M385X		96000 MB/sec
	Difference: 16000 (17%)

Texel Rate

The Radeon R9 M385X will be a bit (about 1%) faster with regards to AF than the Radeon RX 460 2GB. (explain)

Radeon R9 M385X		61600 Mtexels/sec
Radeon RX 460 2GB		61040 Mtexels/sec
	Difference: 560 (1%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 M385X is the winner, but only just. (explain)

Radeon R9 M385X		17600 Mpixels/sec
Radeon RX 460 2GB		17440 Mpixels/sec
	Difference: 160 (1%)

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 (measured in megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's 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 texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core clock speed. 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 is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
