Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M365X should perform much faster than the Radeon HD 3470 512MB overall. (explain)

Radeon R9 M365X		72000 MB/sec
Radeon HD 3470 512MB		30400 MB/sec
	Difference: 41600 (137%)

Texel Rate

The Radeon R9 M365X will be a lot (more or less 1056%) more effective at anisotropic filtering than the Radeon HD 3470 512MB. (explain)

Radeon R9 M365X		37000 Mtexels/sec
Radeon HD 3470 512MB		3200 Mtexels/sec
	Difference: 33800 (1056%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M365X is superior to the Radeon HD 3470 512MB, and very much so. (explain)

Radeon R9 M365X		14800 Mpixels/sec
Radeon HD 3470 512MB		3200 Mpixels/sec
	Difference: 11600 (363%)

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: Memory bandwidth is the max amount of information (measured in MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
