Radeon R9 M380 vs Radeon RX 460

Intro

Compare those specs to the Radeon RX 460, which makes use of a 14 nm design. AMD has clocked the core speed at 1090 MHz. The GDDR5 memory runs at a speed of 1750 MHz on this specific model. It features 896 SPUs as well as 56 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon RX 460 should perform a little bit faster than the Radeon R9 M380 overall. (explain)

Radeon RX 460		112000 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 16000 (17%)

Texel Rate

The Radeon RX 460 is quite a bit (more or less 53%) more effective at anisotropic filtering than the Radeon R9 M380. (explain)

Radeon RX 460		61040 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 21040 (53%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 460 is a better choice, not by a very large margin though. (explain)

Radeon RX 460		17440 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 1440 (9%)

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 largest amount of information (in units of megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher 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 applied in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics 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 the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. 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 output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
