Compare any two graphics cards:
GeForce GT 430 1GB vs GeForce GTX 950M
IntroThe GeForce GT 430 1GB has a GPU core speed of 700 MHz, and the 1024 MB of GDDR3 memory is set to run at 900 MHz through a 128-bit bus. It also is made up of 96 Stream Processors, 16 TAUs, and 4 ROPs.Compare those specs to the GeForce GTX 950M, which comes with a GPU core clock speed of 914 MHz, and 2048 MB of DDR3 RAM running at 1000 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 950M should in theory be just a bit faster than the GeForce GT 430 1GB overall. (explain)
Texel RateThe GeForce GTX 950M is quite a bit (about 226%) more effective at anisotropic filtering than the GeForce GT 430 1GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTX 950M is a better choice, by far. (explain)
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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the largest amount of information (counted in megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher 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 record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
