Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon RX 460 2GB should be 17% quicker than the Radeon R9 M385X in general, due to its greater data rate. (explain)

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

Texel Rate

The Radeon R9 M385X is a small bit (approximately 1%) faster with regards to texture filtering 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

The Radeon R9 M385X is a bit (more or less 1%) more effective at FSAA than the Radeon RX 460 2GB, and able to handle higher screen resolutions better. (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: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 are applied in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the 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 that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
