Radeon R9 M375 vs Radeon RX 460 2GB

Intro

Compare all of that to the Radeon RX 460 2GB, which features a GPU core clock speed of 1090 MHz, and 2048 MB of GDDR5 memory set to run at 1750 MHz through a 128-bit bus. It also is made up of 896 Stream Processors, 56 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon RX 460 2GB, in theory, should be a lot faster than the Radeon R9 M375 in general. (explain)

Radeon RX 460 2GB		112000 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 76800 (218%)

Texel Rate

The Radeon RX 460 2GB should be much (more or less 50%) better at AF than the Radeon R9 M375. (explain)

Radeon RX 460 2GB		61040 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 20440 (50%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 460 2GB is the winner, though only just barely. (explain)

Radeon RX 460 2GB		17440 Mpixels/sec
Radeon R9 M375		16240 Mpixels/sec
	Difference: 1200 (7%)

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 max amount of information (in units of MB per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is worked out 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 most pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out 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 drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of 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.
