GeForce 930M vs GeForce 940M

Intro

Compare those specs to the GeForce 940M, which makes use of a 28 nm design. nVidia has set the core speed at 1072 MHz. The DDR3 memory is set to run at a speed of 1000 MHz on this specific model. It features 384 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

GeForce 930M		14400 MB/sec
	Difference: 1600 (11%)

Texel Rate

The GeForce 940M is a small bit (about 16%) faster with regards to texture filtering than the GeForce 930M. (explain)

GeForce 940M		25728 Mtexels/sec
GeForce 930M		22272 Mtexels/sec
	Difference: 3456 (16%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce 940M is a better choice, not by a very large margin though. (explain)

GeForce 940M		8576 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 1152 (16%)

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 max amount of data (measured in megabytes per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
