GeForce GT 240 GDDR5 vs GeForce GTX 960M

Intro

Compare all that to the GeForce GTX 960M, which makes use of a 28 nm design. nVidia has clocked the core speed at 1096 MHz. The GDDR5 RAM works at a frequency of 1000 MHz on this particular card. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

GeForce GT 240 GDDR5		54400 MB/sec
	Difference: 9600 (18%)

Texel Rate

The GeForce GTX 960M should be quite a bit (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 using high levels of AA is important to you, then the GeForce GTX 960M is superior to the GeForce GT 240 GDDR5, by a large margin. (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 information (measured in MB per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses 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 amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at 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 that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
