Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon HD 6670 (OEM) 1GB should theoretically perform a lot faster than the Radeon R7 M260 overall. (explain)

Radeon HD 6670 (OEM) 1GB		64000 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 48000 (300%)

Texel Rate

The Radeon HD 6670 (OEM) 1GB is a bit (more or less 12%) faster with regards to texture filtering than the Radeon R7 M260. (explain)

Radeon HD 6670 (OEM) 1GB		19200 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 2040 (12%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 6670 (OEM) 1GB is superior to the Radeon R7 M260, but not by far. (explain)

Radeon HD 6670 (OEM) 1GB		6400 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 680 (12%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. 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 high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at 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 card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
