Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R7 M260 will be 11% quicker than the GeForce 830M overall, because of its greater bandwidth. (explain)

Radeon R7 M260		16000 MB/sec
GeForce 830M		14400 MB/sec
	Difference: 1600 (11%)

Texel Rate

The Radeon R7 M260 will be a small bit (more or less 4%) faster with regards to anisotropic filtering than the GeForce 830M. (explain)

Radeon R7 M260		17160 Mtexels/sec
GeForce 830M		16464 Mtexels/sec
	Difference: 696 (4%)

Pixel Rate

The GeForce 830M is a lot (approximately 44%) better at FSAA than the Radeon R7 M260, and also will be able to handle higher resolutions without losing too much performance. (explain)

GeForce 830M		8232 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 2512 (44%)

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: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels 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 figure is worked out by multiplying the amount of Render Output Units 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, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
