GeForce GT 130 vs GeForce GTX 950M

Intro

Compare those specs 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 works at a frequency of 1000 MHz on this specific card. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 950M		55 Watts
GeForce GT 130		75 Watts
	Difference: 20 Watts (36%)

Memory Bandwidth

The GeForce GTX 950M should in theory perform a lot faster than the GeForce GT 130 overall. (explain)

GeForce GTX 950M		32000 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 20000 (167%)

Texel Rate

The GeForce GTX 950M should be much (more or less 205%) more effective at texture filtering than the GeForce GT 130. (explain)

GeForce GTX 950M		36560 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 24560 (205%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 950M is superior to the GeForce GT 130, by a large margin. (explain)

GeForce GTX 950M		14624 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 6624 (83%)

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 transferred past the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated 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 also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
