Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 860M		45 Watts
Radeon HD 5750 1GB		86 Watts
	Difference: 41 Watts (91%)

Memory Bandwidth

In theory, the Radeon HD 5750 1GB will be 15% faster than the GeForce GTX 860M overall, because of its higher data rate. (explain)

Radeon HD 5750 1GB		73600 MB/sec
GeForce GTX 860M		64000 MB/sec
	Difference: 9600 (15%)

Texel Rate

The GeForce GTX 860M is quite a bit (about 204%) faster with regards to AF than the Radeon HD 5750 1GB. (explain)

GeForce GTX 860M		76512 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 51312 (204%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 860M is the winner, though only just barely. (explain)

GeForce GTX 860M		12752 Mpixels/sec
Radeon HD 5750 1GB		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 maximum amount of data (in units of MB per second) that can be transported past the external memory interface in a second. It's 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 it uses DDR5, multiply by 4 instead. The better the 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 number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could 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 Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
