Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M370X should in theory be a small bit faster than the Radeon HD 6670 (OEM) 1GB in general. (explain)

Radeon R9 M370X		72000 MB/sec
Radeon HD 6670 (OEM) 1GB		64000 MB/sec
	Difference: 8000 (13%)

Texel Rate

The Radeon R9 M370X is quite a bit (more or less 67%) faster with regards to anisotropic filtering than the Radeon HD 6670 (OEM) 1GB. (explain)

Radeon R9 M370X		32000 Mtexels/sec
Radeon HD 6670 (OEM) 1GB		19200 Mtexels/sec
	Difference: 12800 (67%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R9 M370X is the winner, and very much so. (explain)

Radeon R9 M370X		12800 Mpixels/sec
Radeon HD 6670 (OEM) 1GB		6400 Mpixels/sec
	Difference: 6400 (100%)

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 megabytes per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is calculated 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs 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 fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
