GeForce 930M vs GeForce 940M

Intro

The GeForce 930M features core clock speeds of 928 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 384 SPUs along with 24 Texture Address Units and 8 ROPs.

Compare those specifications to the GeForce 940M, which comes with a core clock speed of 1072 MHz and a DDR3 memory frequency of 1000 MHz. It also features a 64-bit bus, and uses a 28 nm design. It is made up of 384 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 940M should in theory be just a bit faster than the GeForce 930M in general. (explain)

GeForce 940M 16000 MB/sec
GeForce 930M 14400 MB/sec
Difference: 1600 (11%)

Texel Rate

The GeForce 940M is a little 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 running with high levels of AA is important to you, then the GeForce 940M is the winner, 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.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of MB per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also 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 of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
