Compare any two graphics cards:
GeForce GT 420 vs GeForce GTX 950M
IntroThe GeForce GT 420 uses a 40 nm design. nVidia has set the core frequency at 700 MHz. The GDDR3 RAM is set to run at a speed of 900 MHz on this model. It features 48 SPUs as well as 8 TAUs and 4 Rasterization Operator Units.Compare that to the GeForce GTX 950M, which has 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 made up of 640 Stream Processors, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 950M should perform just a bit faster than the GeForce GT 420 in general. (explain)
Texel RateThe GeForce GTX 950M should be quite a bit (about 553%) better at anisotropic filtering than the GeForce GT 420. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 950M is the winner, and very much so. (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: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units by the core clock 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 in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its 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 clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
