Radeon R9 M375X vs Radeon RX 580

Intro

Compare those specs to the Radeon RX 580, which has core clock speeds of 1257 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 RAM. It features 2304 SPUs along with 144 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon RX 580 should perform much faster than the Radeon R9 M375X overall. (explain)

Radeon RX 580		262144 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 190144 (264%)

Texel Rate

The Radeon RX 580 should be quite a bit (approximately 346%) faster with regards to texture filtering than the Radeon R9 M375X. (explain)

Radeon RX 580		181008 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 140408 (346%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 580 is the winner, and very much so. (explain)

Radeon RX 580		40224 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 23984 (148%)

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 transported over the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's 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 are applied per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core 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, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
