Radeon R9 M370X vs Radeon RX 580

Intro

Compare those specs to the Radeon RX 580, which features GPU clock speed of 1257 MHz, and 8192 MB of GDDR5 RAM set to run at 2000 MHz through a 256-bit bus. It also is made up of 2304 SPUs, 144 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon RX 580 should be quite a bit faster than the Radeon R9 M370X overall. (explain)

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

Texel Rate

The Radeon RX 580 will be a lot (about 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 the winner, by far. (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: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. 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 output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
