GeForce 940M vs GeForce GTX 950M

Intro

The GeForce 940M uses a 28 nm design. nVidia has clocked the core frequency at 1072 MHz. The DDR3 RAM is set to run at a frequency of 1000 MHz on this specific model. It features 384 SPUs along with 24 TAUs and 8 ROPs.

Compare those specs to the GeForce GTX 950M, which comes with a clock frequency of 914 MHz and a DDR3 memory speed of 1000 MHz. It also features a 128-bit bus, and uses a 28 nm design. It features 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 950M is 100% quicker than the GeForce 940M in general, because of its greater bandwidth. (explain)

GeForce GTX 950M 32000 MB/sec
GeForce 940M 16000 MB/sec
Difference: 16000 (100%)

Texel Rate

The GeForce GTX 950M is quite a bit (more or less 42%) more effective at texture filtering than the GeForce 940M. (explain)

GeForce GTX 950M 36560 Mtexels/sec
GeForce 940M 25728 Mtexels/sec
Difference: 10832 (42%)

Pixel Rate

The GeForce GTX 950M is quite a bit (about 71%) more effective at anti-aliasing than the GeForce 940M, and also should be able to handle higher resolutions more effectively. (explain)

GeForce GTX 950M 14624 Mpixels/sec
GeForce 940M 8576 Mpixels/sec
Difference: 6048 (71%)

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.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the graphics 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 maximum number of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock 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 is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
