GeForce GT 430 vs GeForce GTX 950M

Intro

Compare all of that to the GeForce GTX 950M, which comes with clock speeds of 914 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 640 SPUs as well as 40 TAUs 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

Performance-wise, the GeForce GTX 950M should in theory be just a bit superior to the GeForce GT 430 overall. (explain)

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

Texel Rate

The GeForce GTX 950M will be much (about 226%) more effective at texture filtering than the GeForce GT 430. (explain)

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

Pixel Rate

The GeForce GTX 950M will be quite a bit (more or less 422%) faster with regards to full screen anti-aliasing than the GeForce GT 430, and also will be able to handle higher screen resolutions without losing too much performance. (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 transported over the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
