Compare any two graphics cards:
GeForce 830M vs GeForce GT 440 1.5GB
IntroThe GeForce 830M uses a 28 nm design. nVidia has set the core frequency at 1029 MHz. The DDR3 memory runs at a frequency of 900 MHz on this particular model. It features 256 SPUs along with 16 Texture Address Units and 8 Rasterization Operator Units.Compare all of that to the GeForce GT 440 1.5GB, which has a core clock speed of 594 MHz and a GDDR3 memory frequency of 900 MHz. It also makes use of a 192-bit bus, and uses a 40 nm design. It is made up of 144 SPUs, 24 TAUs, and 24 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GT 440 1.5GB will be 200% faster than the GeForce 830M overall, because of its higher bandwidth. (explain)
Texel RateThe GeForce 830M will be a small bit (approximately 15%) better at texture filtering than the GeForce GT 440 1.5GB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GT 440 1.5GB 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 max amount of data (measured in MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total texture units of the card 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 applied in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
