GeForce GT 430 (OEM) vs GeForce GTX 950M

Intro

Compare all that to the GeForce GTX 950M, which makes use of a 28 nm design. nVidia has clocked the core frequency at 914 MHz. The DDR3 RAM is set to run at a speed of 1000 MHz on this specific model. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

GeForce GT 430 (OEM)		28800 MB/sec
	Difference: 3200 (11%)

Texel Rate

The GeForce GTX 950M will be a lot (more or less 226%) better at texture filtering than the GeForce GT 430 (OEM). (explain)

GeForce GTX 950M		36560 Mtexels/sec
GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 25360 (226%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 950M is the winner, by a large margin. (explain)

GeForce GTX 950M		14624 Mpixels/sec
GeForce GT 430 (OEM)		2800 Mpixels/sec
	Difference: 11824 (422%)

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 (in units of MB per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses 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 amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the 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 write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
