GeForce GT 240 GDDR5 vs GeForce GTX 960M

Intro

Compare all that to the GeForce GTX 960M, which features GPU core speed of 1096 MHz, and 2048 MB of GDDR5 RAM running at 1000 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

	Difference: 5 Watts (8%)

Memory Bandwidth

In theory, the GeForce GTX 960M will be 18% faster than the GeForce GT 240 GDDR5 in general, because of its higher data rate. (explain)

GeForce GTX 960M		64000 MB/sec
GeForce GT 240 GDDR5		54400 MB/sec
	Difference: 9600 (18%)

Texel Rate

The GeForce GTX 960M is much (approximately 149%) more effective at AF than the GeForce GT 240 GDDR5. (explain)

GeForce GTX 960M		43840 Mtexels/sec
GeForce GT 240 GDDR5		17600 Mtexels/sec
	Difference: 26240 (149%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 960M is superior to the GeForce GT 240 GDDR5, and very much so. (explain)

GeForce GTX 960M		17536 Mpixels/sec
GeForce GT 240 GDDR5		4400 Mpixels/sec
	Difference: 13136 (299%)

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 largest amount of data (counted in megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the 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 in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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