Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 9800 GT 512MB should be quite a bit faster than the GeForce 930M in general. (explain)

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

Texel Rate

The GeForce 9800 GT 512MB is quite a bit (approximately 51%) more effective 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 running with a high screen resolution is important to you, then the GeForce 9800 GT 512MB is a better choice, by a large margin. (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: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 number of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
