Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M390X, in theory, should be much faster than the Radeon HD 3470 512MB overall. (explain)

Radeon R9 M390X		160000 MB/sec
Radeon HD 3470 512MB		30400 MB/sec
	Difference: 129600 (426%)

Texel Rate

The Radeon R9 M390X is much (more or less 2792%) faster with regards to anisotropic filtering than the Radeon HD 3470 512MB. (explain)

Radeon R9 M390X		92544 Mtexels/sec
Radeon HD 3470 512MB		3200 Mtexels/sec
	Difference: 89344 (2792%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M390X is superior to the Radeon HD 3470 512MB, and very much so. (explain)

Radeon R9 M390X		23136 Mpixels/sec
Radeon HD 3470 512MB		3200 Mpixels/sec
	Difference: 19936 (623%)

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 data (in units of MB per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total texture units by the core 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
