Radeon R9 M370X vs Radeon RX 580

Intro

Compare those specs to the Radeon RX 580, which features a GPU core clock speed of 1257 MHz, and 8192 MB of GDDR5 memory running at 2000 MHz through a 256-bit bus. It also is comprised of 2304 SPUs, 144 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon RX 580, in theory, should be quite a bit faster than the Radeon R9 M370X in general. (explain)

Radeon RX 580		262144 MB/sec
Radeon R9 M370X		72000 MB/sec
	Difference: 190144 (264%)

Texel Rate

The Radeon RX 580 will be much (approximately 466%) better at anisotropic filtering than the Radeon R9 M370X. (explain)

Radeon RX 580		181008 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 149008 (466%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 580 is a better choice, and very much so. (explain)

Radeon RX 580		40224 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 27424 (214%)

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 max amount of data (measured in megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
