Compare any two graphics cards:
GeForce 830M vs GeForce 8800 Ultra
IntroThe GeForce 830M makes use of a 28 nm design. nVidia has set the core speed at 1029 MHz. The DDR3 memory is set to run at a frequency of 900 MHz on this specific model. It features 256 SPUs along with 16 Texture Address Units and 8 ROPs.Compare those specs to the GeForce 8800 Ultra, which features a clock speed of 612 MHz and a GDDR3 memory speed of 1080 MHz. It also uses a 384-bit memory bus, and uses a 90 nm design. It is comprised of 128 SPUs, 64 Texture Address Units, and 24 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce 8800 Ultra should be 620% faster than the GeForce 830M overall, due to its greater data rate. (explain)
Texel RateThe GeForce 8800 Ultra should be a lot (about 138%) more effective at anisotropic filtering than the GeForce 830M. (explain)
Pixel RateThe GeForce 8800 Ultra is a lot (more or less 78%) faster with regards to anti-aliasing than the GeForce 830M, and able to handle higher resolutions while still performing well. (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 max amount of information (measured in megabytes per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the 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 maximum number of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
