Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 860M		45 Watts
Radeon HD 5750 512MB		86 Watts
	Difference: 41 Watts (91%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 5750 512MB should be 15% quicker than the GeForce GTX 860M overall, because of its greater data rate. (explain)

Radeon HD 5750 512MB		73600 MB/sec
GeForce GTX 860M		64000 MB/sec
	Difference: 9600 (15%)

Texel Rate

The GeForce GTX 860M should be much (more or less 204%) better at anisotropic filtering than the Radeon HD 5750 512MB. (explain)

GeForce GTX 860M		76512 Mtexels/sec
Radeon HD 5750 512MB		25200 Mtexels/sec
	Difference: 51312 (204%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 860M is superior to the Radeon HD 5750 512MB, but not by far. (explain)

GeForce GTX 860M		12752 Mpixels/sec
Radeon HD 5750 512MB		11200 Mpixels/sec
	Difference: 1552 (14%)

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 largest amount of data (measured in MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the 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 number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
