GeForce GT 430 vs GeForce GTX 950M

Intro

The GeForce GT 430 comes with a GPU core speed of 700 MHz, and the 512 MB of GDDR3 RAM is set to run at 900 MHz through a 128-bit bus. It also is comprised of 96 Stream Processors, 16 TAUs, and 4 ROPs.

Compare those specs to the GeForce GTX 950M, which comes with a core clock speed of 914 MHz and a DDR3 memory frequency of 1000 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 ROPs.

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

Pixel Rate

The GeForce GTX 950M will be a lot (more or less 422%) better at full screen anti-aliasing than the GeForce GT 430, and will be capable of handling 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.

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the 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 amount of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
