GeForce GT 240 GDDR5 vs GeForce GTX 960M

Intro

Compare all that to the GeForce GTX 960M, which comes with clock speeds of 1096 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs along with 40 TAUs and 16 ROPs.

GeForce GTX 960M		65 Watts
GeForce GT 240 GDDR5		70 Watts
	Difference: 5 Watts (8%)

Memory Bandwidth

In theory, the GeForce GTX 960M should be 18% faster than the GeForce GT 240 GDDR5 overall, due to its higher bandwidth. (explain)

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

Texel Rate

The GeForce GTX 960M should be quite a bit (about 149%) faster with regards to anisotropic filtering 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

The GeForce GTX 960M is quite a bit (about 299%) more effective at AA than the GeForce GT 240 GDDR5, and able to handle higher screen resolutions more effectively. (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: Bandwidth is the largest amount of data (in units of MB per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the 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 - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends 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.
