Radeon R9 380X vs Radeon RX 460 2GB

Intro

Compare those specifications to the Radeon RX 460 2GB, which makes use of a 14 nm design. AMD has set the core speed at 1090 MHz. The GDDR5 RAM runs at a speed of 1750 MHz on this particular card. It features 896 SPUs as well as 56 TAUs and 16 ROPs.

Radeon RX 460 2GB		75 Watts
Radeon R9 380X		190 Watts
	Difference: 115 Watts (153%)

Memory Bandwidth

In theory, the Radeon R9 380X should perform a lot faster than the Radeon RX 460 2GB overall. (explain)

Radeon R9 380X		182400 MB/sec
Radeon RX 460 2GB		112000 MB/sec
	Difference: 70400 (63%)

Texel Rate

The Radeon R9 380X should be quite a bit (about 103%) better at texture filtering 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 running with high levels of AA is important to you, then the Radeon R9 380X is the winner, by far. (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: Bandwidth is the max amount of information (counted in megabytes per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has 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 faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
