GeForce GTX 860M 45 Watts
Radeon HD 6670 (OEM) 1GB 63 Watts
Difference: 18 Watts (40%)

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so in theory they should have the same performance. (explain)

Texel Rate

The GeForce GTX 860M is much (approximately 299%) better at texture filtering than the Radeon HD 6670 (OEM) 1GB. (explain)

GeForce GTX 860M 76512 Mtexels/sec
Radeon HD 6670 (OEM) 1GB 19200 Mtexels/sec
Difference: 57312 (299%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 860M is superior to the Radeon HD 6670 (OEM) 1GB, and very much so. (explain)

GeForce GTX 860M 12752 Mpixels/sec
Radeon HD 6670 (OEM) 1GB 6400 Mpixels/sec
Difference: 6352 (99%)

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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, 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 maximum amount of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of 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 output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
