Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 9800 GT 512MB is 300% faster than the GeForce 930M in general, because of its higher data rate. (explain)

GeForce 9800 GT 512MB		57600 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 43200 (300%)

Texel Rate

The GeForce 9800 GT 512MB should be quite a bit (more or less 51%) better at anisotropic filtering than the GeForce 930M. (explain)

GeForce 9800 GT 512MB		33600 Mtexels/sec
GeForce 930M		22272 Mtexels/sec
	Difference: 11328 (51%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce 9800 GT 512MB is the winner, and very much so. (explain)

GeForce 9800 GT 512MB		9600 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 2176 (29%)

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 max amount of data (in units of MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
