Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 9500 GT 1GB GDDR3 should in theory perform quite a bit faster than the GeForce 930M in general. (explain)

GeForce 9500 GT 1GB GDDR3		25600 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 11200 (78%)

Texel Rate

The GeForce 930M should be much (approximately 153%) more effective at AF than the GeForce 9500 GT 1GB GDDR3. (explain)

GeForce 930M		22272 Mtexels/sec
GeForce 9500 GT 1GB GDDR3		8800 Mtexels/sec
	Difference: 13472 (153%)

Pixel Rate

The GeForce 930M should be much (approximately 69%) more effective at full screen anti-aliasing than the GeForce 9500 GT 1GB GDDR3, and should be able to handle higher resolutions more effectively. (explain)

GeForce 930M		7424 Mpixels/sec
GeForce 9500 GT 1GB GDDR3		4400 Mpixels/sec
	Difference: 3024 (69%)

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 (counted in megabytes per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it must 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 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 calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the 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 maximum number of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core 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 rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
