Compare any two graphics cards:
VS

GeForce GTX 860M vs Radeon HD 6670 (OEM) 1GB

Intro

The GeForce GTX 860M comes with clock speeds of 797 MHz on the GPU, and 1000 MHz on the 4096 MB of GDDR5 RAM. It features 1152 SPUs along with 96 TAUs and 16 Rasterization Operator Units.

Compare that to the Radeon HD 6670 (OEM) 1GB, which uses a 40 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 RAM works at a frequency of 1000 MHz on this specific model. It features 480 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Both cards have the exact same memory bandwidth, so theoretically they should perform the same. (explain)

Texel Rate

The GeForce GTX 860M is quite a bit (more or less 299%) more effective 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 running with high levels of AA is important to you, then the GeForce GTX 860M is superior to the Radeon HD 6670 (OEM) 1GB, by a large margin. (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: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. 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 output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
