Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon HD 3650 512MB should in theory be much superior to the GeForce 930M in general. (explain)

Radeon HD 3650 512MB		25600 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 11200 (78%)

Texel Rate

The GeForce 930M should be quite a bit (about 284%) more effective at texture filtering than the Radeon HD 3650 512MB. (explain)

GeForce 930M		22272 Mtexels/sec
Radeon HD 3650 512MB		5800 Mtexels/sec
	Difference: 16472 (284%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce 930M is superior to the Radeon HD 3650 512MB, by a large margin. (explain)

GeForce 930M		7424 Mpixels/sec
Radeon HD 3650 512MB		2900 Mpixels/sec
	Difference: 4524 (156%)

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 over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, 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 number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics 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 most pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs 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 fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
