Compare any two graphics cards:
GeForce 830M vs GeForce GTX 550 Ti
IntroThe GeForce 830M features a GPU clock speed of 1029 MHz, and the 2048 MB of DDR3 memory runs at 900 MHz through a 64-bit bus. It also is comprised of 256 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.Compare those specs to the GeForce GTX 550 Ti, which features GPU clock speed of 900 MHz, and 1024 MB of GDDR5 memory set to run at 1026 MHz through a 192-bit bus. It also is made up of 192 SPUs, 32 TAUs, and 24 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 550 Ti should in theory perform quite a bit faster than the GeForce 830M in general. (explain)
Texel RateThe GeForce GTX 550 Ti is a lot (more or less 75%) more effective at anisotropic filtering than the GeForce 830M. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 550 Ti is superior to the GeForce 830M, 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: Bandwidth is the max amount of information (counted in MB per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 texture map elements (texels) that are applied per second. This number is calculated by multiplying the total texture units of the card 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 applied per second. Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in a 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 - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
