Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GT 240 GDDR5 1GB should theoretically be quite a bit superior to the GeForce 930M overall. (explain)

GeForce GT 240 GDDR5 1GB		54400 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 40000 (278%)

Texel Rate

The GeForce 930M should be a lot (approximately 27%) faster with regards to anisotropic filtering than the GeForce GT 240 GDDR5 1GB. (explain)

GeForce 930M		22272 Mtexels/sec
GeForce GT 240 GDDR5 1GB		17600 Mtexels/sec
	Difference: 4672 (27%)

Pixel Rate

The GeForce 930M will be a lot (more or less 69%) more effective at FSAA than the GeForce GT 240 GDDR5 1GB, and will be capable of handling higher resolutions without losing too much performance. (explain)

GeForce 930M		7424 Mpixels/sec
GeForce GT 240 GDDR5 1GB		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: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better 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 number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill 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 ability to reach the max fill rate.
