Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M375 will be 16% quicker than the Radeon HD 3470 512MB overall, due to its higher data rate. (explain)

Radeon R9 M375		35200 MB/sec
Radeon HD 3470 512MB		30400 MB/sec
	Difference: 4800 (16%)

Texel Rate

The Radeon R9 M375 will be quite a bit (more or less 1169%) faster with regards to AF than the Radeon HD 3470 512MB. (explain)

Radeon R9 M375		40600 Mtexels/sec
Radeon HD 3470 512MB		3200 Mtexels/sec
	Difference: 37400 (1169%)

Pixel Rate

The Radeon R9 M375 should be a lot (approximately 408%) better at AA than the Radeon HD 3470 512MB, and should be able to handle higher resolutions better. (explain)

Radeon R9 M375		16240 Mpixels/sec
Radeon HD 3470 512MB		3200 Mpixels/sec
	Difference: 13040 (408%)

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 (measured in MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video 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 maximum number of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
