Radeon R9 M380 vs Radeon RX 460

Intro

Compare all that to the Radeon RX 460, which has a core clock speed of 1090 MHz and a GDDR5 memory frequency of 1750 MHz. It also features a 128-bit memory bus, and makes use of a 14 nm design. It is comprised of 896 SPUs, 56 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon RX 460 should be a small bit faster than the Radeon R9 M380 in general. (explain)

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

Texel Rate

The Radeon RX 460 will be much (about 53%) more effective at texture 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 using 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: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the 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 the video card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
