GeForce GT 430 1GB vs GeForce GTX 950M

Intro

The GeForce GT 430 1GB comes with a GPU core clock speed of 700 MHz, and the 1024 MB of GDDR3 RAM runs at 900 MHz through a 128-bit bus. It also is comprised of 96 SPUs, 16 Texture Address Units, and 4 ROPs.

Compare those specifications to the GeForce GTX 950M, which comes with a clock frequency of 914 MHz and a DDR3 memory frequency of 1000 MHz. It also uses a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 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 1GB 60 Watts
Difference: 5 Watts (9%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 950M is 11% faster than the GeForce GT 430 1GB overall, because of its higher bandwidth. (explain)

GeForce GTX 950M 32000 MB/sec
GeForce GT 430 1GB 28800 MB/sec
Difference: 3200 (11%)

Texel Rate

The GeForce GTX 950M is quite a bit (about 226%) more effective at anisotropic filtering than the GeForce GT 430 1GB. (explain)

GeForce GTX 950M 36560 Mtexels/sec
GeForce GT 430 1GB 11200 Mtexels/sec
Difference: 25360 (226%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 950M is superior to the GeForce GT 430 1GB, and very much so. (explain)

GeForce GTX 950M 14624 Mpixels/sec
GeForce GT 430 1GB 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.

Memory Bandwidth: Bandwidth is the max amount of information (measured in MB per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units of the card 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
