GeForce GT 130 vs GeForce GTX 960M

Intro

Compare that to the GeForce GTX 960M, which comes with GPU clock speed of 1096 MHz, and 2048 MB of GDDR5 RAM set to run 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.

GeForce GT 130		12000 MB/sec
	Difference: 52000 (433%)

Texel Rate

The GeForce GTX 960M will be a lot (approximately 265%) more effective at anisotropic filtering than the GeForce GT 130. (explain)

GeForce GTX 960M		43840 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 31840 (265%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 960M is superior to the GeForce GT 130, by far. (explain)

GeForce GTX 960M		17536 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 9536 (119%)

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 (counted in megabytes per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses 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 are processed in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip 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 number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel 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 reach the max fill rate.
