Radeon R9 M370X vs Radeon RX 580

Intro

Compare those specifications to the Radeon RX 580, which makes use of a 14 nm design. AMD has clocked the core speed at 1257 MHz. The GDDR5 memory works at a speed of 2000 MHz on this particular card. It features 2304 SPUs as well as 144 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon RX 580 should in theory be quite a bit superior to 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 (about 466%) better at texture filtering than the Radeon R9 M370X. (explain)

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

Pixel Rate

The Radeon RX 580 should be a lot (approximately 214%) more effective at anti-aliasing than the Radeon R9 M370X, and able to handle higher resolutions while still performing well. (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 largest amount of data (in units of MB per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it must 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, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel 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 ability to get to the maximum fill rate.
