Radeon R9 M380 vs Radeon RX 460

Intro

The Radeon R9 M380 has a GPU core speed of 1000 MHz, and the 4096 MB of GDDR5 RAM runs at 1500 MHz through a 128-bit bus. It also features 640 Stream Processors, 40 TAUs, and 16 Raster Operation Units.

Compare that to the Radeon RX 460, which has core speeds of 1090 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 896 SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon RX 460 should be a little 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 (approximately 53%) more effective at AF 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 resolution is important to you, then the Radeon RX 460 is superior to the Radeon R9 M380, but only just. (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.

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in MB per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 are applied in one second. This 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 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 most pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
