GeForce 940M vs GeForce GTX 960M

Intro

Compare all of that to the GeForce GTX 960M, which uses a 28 nm design. nVidia has clocked the core frequency at 1096 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this particular model. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

GeForce 940M		16000 MB/sec
	Difference: 48000 (300%)

Texel Rate

The GeForce GTX 960M will be quite a bit (approximately 70%) faster with regards to texture filtering than the GeForce 940M. (explain)

GeForce GTX 960M		43840 Mtexels/sec
GeForce 940M		25728 Mtexels/sec
	Difference: 18112 (70%)

Pixel Rate

The GeForce GTX 960M is a lot (approximately 104%) more effective at AA than the GeForce 940M, and also should be able to handle higher screen resolutions better. (explain)

GeForce GTX 960M		17536 Mpixels/sec
GeForce 940M		8576 Mpixels/sec
	Difference: 8960 (104%)

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 (in units of MB per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once 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 anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video 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 can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines 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 also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
