GeForce GT 430 vs GeForce GTX 950M

Intro

Compare those specifications to the GeForce GTX 950M, which features a core clock speed of 914 MHz and a DDR3 memory speed of 1000 MHz. It also features a 128-bit bus, and uses a 28 nm design. It features 640 SPUs, 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

Performance-wise, the GeForce GTX 950M should in theory be just a bit better than the GeForce GT 430 in general. (explain)

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

Texel Rate

The GeForce GTX 950M should be a lot (more or less 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 should be quite a bit (approximately 422%) faster with regards to AA than the GeForce GT 430, and should be able to handle higher resolutions while still performing well. (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: Bandwidth is the max amount of data (counted in megabytes per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen 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 by the core 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 a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
