GeForce 940M vs GeForce GTX 950M


Intro

The GeForce 940M has a core clock speed of 1072 MHz and a DDR3 memory speed of 1000 MHz. It also features a 64-bit bus, and uses a 28 nm design. It is comprised of 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Compare all that to the GeForce GTX 950M, which has core speeds of 914 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

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

Texel Rate

The GeForce GTX 950M will be quite a bit (more or less 42%) faster with regards to AF than the GeForce 940M. (explain)

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

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 950M is a better choice, and very much so. (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: Bandwidth is the maximum amount of information (counted in MB per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
