GeForce 940M vs GeForce GT 430 1GB

Intro

Compare that to the GeForce GT 430 1GB, which features core clock speeds of 700 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR3 RAM. It features 96 SPUs along with 16 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GT 430 1GB should be a lot faster than the GeForce 940M in general. (explain)

GeForce GT 430 1GB		28800 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 12800 (80%)

Texel Rate

The GeForce 940M will be quite a bit (about 130%) more effective at texture filtering than the GeForce GT 430 1GB. (explain)

GeForce 940M		25728 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 14528 (130%)

Pixel Rate

The GeForce 940M is much (more or less 206%) faster with regards to AA than the GeForce GT 430 1GB, and should be able to handle higher resolutions without slowing down too much. (explain)

GeForce 940M		8576 Mpixels/sec
GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 5776 (206%)

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 largest amount of information (counted in megabytes per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
