Radeon R9 M380 vs Radeon RX 460 2GB

Intro

The Radeon R9 M380 has a core clock speed of 1000 MHz and a GDDR5 memory speed of 1500 MHz. It also makes use of a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Compare those specs to the Radeon RX 460 2GB, which has a GPU core clock speed of 1090 MHz, and 2048 MB of GDDR5 memory running at 1750 MHz through a 128-bit bus. It also is comprised of 896 Stream Processors, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon RX 460 2GB should in theory perform a small bit faster than the Radeon R9 M380 in general. (explain)

Radeon RX 460 2GB 112000 MB/sec
Radeon R9 M380 96000 MB/sec
Difference: 16000 (17%)

Texel Rate

The Radeon RX 460 2GB will be much (about 53%) better at texture filtering than the Radeon R9 M380. (explain)

Radeon RX 460 2GB 61040 Mtexels/sec
Radeon R9 M380 40000 Mtexels/sec
Difference: 21040 (53%)

Pixel Rate

The Radeon RX 460 2GB is a little bit (approximately 9%) faster with regards to FSAA than the Radeon R9 M380, and also should be capable of handling higher screen resolutions better. (explain)

Radeon RX 460 2GB 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: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 number of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of 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 processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
