Radeon RX 460 2GB		112000 MB/sec
	Difference: 70400 (63%)

Texel Rate

The Radeon R9 380X will be much (approximately 103%) faster with regards to AF than the Radeon RX 460 2GB. (explain)

Radeon R9 380X		124160 Mtexels/sec
Radeon RX 460 2GB		61040 Mtexels/sec
	Difference: 63120 (103%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 380X is superior to the Radeon RX 460 2GB, and very much so. (explain)

Radeon R9 380X		31040 Mpixels/sec
Radeon RX 460 2GB		17440 Mpixels/sec
	Difference: 13600 (78%)

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 largest amount of data (in units of megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the video 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 card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
