Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M370X will be 137% quicker than the Radeon HD 3470 512MB overall, due to its higher bandwidth. (explain)

Radeon R9 M370X		72000 MB/sec
Radeon HD 3470 512MB		30400 MB/sec
	Difference: 41600 (137%)

Texel Rate

The Radeon R9 M370X should be a lot (approximately 900%) more effective at anisotropic filtering than the Radeon HD 3470 512MB. (explain)

Radeon R9 M370X		32000 Mtexels/sec
Radeon HD 3470 512MB		3200 Mtexels/sec
	Difference: 28800 (900%)

Pixel Rate

The Radeon R9 M370X is a lot (more or less 300%) more effective at full screen anti-aliasing than the Radeon HD 3470 512MB, and capable of handling higher screen resolutions more effectively. (explain)

Radeon R9 M370X		12800 Mpixels/sec
Radeon HD 3470 512MB		3200 Mpixels/sec
	Difference: 9600 (300%)

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 within a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units 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 applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
