GeForce 940M vs GeForce GT 320

Intro

The GeForce 940M features clock speeds of 1072 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 384 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Compare all of that to the GeForce GT 320, which comes with core speeds of 540 MHz on the GPU, and 790 MHz on the 1024 MB of GDDR3 RAM. It features 72 SPUs along with 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GT 320 should theoretically be quite a bit superior to the GeForce 940M in general. (explain)

GeForce GT 320 25280 MB/sec
GeForce 940M 16000 MB/sec
Difference: 9280 (58%)

Texel Rate

The GeForce 940M should be much (about 99%) better at texture filtering than the GeForce GT 320. (explain)

GeForce 940M 25728 Mtexels/sec
GeForce GT 320 12960 Mtexels/sec
Difference: 12768 (99%)

Pixel Rate

The GeForce 940M should be a lot (more or less 99%) better at AA than the GeForce GT 320, and capable of handling higher resolutions without slowing down too much. (explain)

GeForce 940M 8576 Mpixels/sec
GeForce GT 320 4320 Mpixels/sec
Difference: 4256 (99%)

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 max amount of information (in units of MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of texture units by the core clock 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 in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
