GeForce 930M vs GeForce GT 240 GDDR5

Intro

Compare that to the GeForce GT 240 GDDR5, which makes use of a 40 nm design. nVidia has clocked the core frequency at 550 MHz. The GDDR5 memory is set to run at a speed of 850 MHz on this specific model. It features 96 SPUs along with 32 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GT 240 GDDR5 should in theory perform much faster than the GeForce 930M overall. (explain)

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

Texel Rate

The GeForce 930M is quite a bit (approximately 27%) faster with regards to texture filtering than the GeForce GT 240 GDDR5. (explain)

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

Pixel Rate

The GeForce 930M is quite a bit (approximately 69%) better at full screen anti-aliasing than the GeForce GT 240 GDDR5, and will be capable of handling higher resolutions without slowing down too much. (explain)

GeForce 930M		7424 Mpixels/sec
GeForce GT 240 GDDR5		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 information (in units of megabytes per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
