Compare any two graphics cards:
GeForce 8800 Ultra vs GeForce GTX 880M
IntroThe GeForce 8800 Ultra has a GPU clock speed of 612 MHz, and the 768 MB of GDDR3 memory is set to run at 1080 MHz through a 384-bit bus. It also is comprised of 128 Stream Processors, 64 Texture Address Units, and 24 ROPs.Compare all that to the GeForce GTX 880M, which features a GPU core clock speed of 954 MHz, and 4096 MB of GDDR5 memory set to run at 1000 MHz through a 256-bit bus. It also is made up of 1536 SPUs, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 880M is 23% quicker than the GeForce 8800 Ultra overall, due to its higher bandwidth. (explain)
Texel RateThe GeForce GTX 880M will be quite a bit (more or less 212%) faster with regards to AF than the GeForce 8800 Ultra. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 880M 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: Bandwidth is the largest amount of information (in units of megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video 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 maximum number of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines 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 of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
