GeForce GT 430 vs GeForce GTX 950M

Intro

Compare those specs to the GeForce GTX 950M, which has clock speeds of 914 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 950M		55 Watts
GeForce GT 430		60 Watts
	Difference: 5 Watts (9%)

Memory Bandwidth

In theory, the GeForce GTX 950M should be 11% quicker than the GeForce GT 430 overall, due to its higher data rate. (explain)

GeForce GTX 950M		32000 MB/sec
GeForce GT 430		28800 MB/sec
	Difference: 3200 (11%)

Texel Rate

The GeForce GTX 950M should be much (more or less 226%) better at anisotropic filtering than the GeForce GT 430. (explain)

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

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 950M is a better choice, and very much so. (explain)

GeForce GTX 950M		14624 Mpixels/sec
GeForce GT 430		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: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 can be applied in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
