Radeon R9 M370X vs Radeon RX 480

Intro

Compare that to the Radeon RX 480, which features a GPU core clock speed of 1120 MHz, and 8192 MB of GDDR5 memory set to run at 2000 MHz through a 256-bit bus. It also is made up of 2304 Stream Processors, 144 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon RX 480 should be 264% faster than the Radeon R9 M370X in general, due to its greater bandwidth. (explain)

Radeon RX 480		262144 MB/sec
Radeon R9 M370X		72000 MB/sec
	Difference: 190144 (264%)

Texel Rate

The Radeon RX 480 will be a lot (approximately 404%) more effective at AF than the Radeon R9 M370X. (explain)

Radeon RX 480		161280 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 129280 (404%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 480 is superior to the Radeon R9 M370X, and very much so. (explain)

Radeon RX 480		35840 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 23040 (180%)

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 maximum amount of information (measured in MB per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

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