Compare any two graphics cards:
GeForce 825M vs GeForce 8600 GT 256MB DDR2
IntroThe GeForce 825M has a GPU core clock speed of 850 MHz, and the 2048 MB of DDR3 RAM runs at 900 MHz through a 64-bit bus. It also features 384 Stream Processors, 16 TAUs, and 8 Raster Operation Units.Compare all that to the GeForce 8600 GT 256MB DDR2, which comes with GPU clock speed of 540 MHz, and 256 MB of DDR2 RAM running at 400 MHz through a 128-bit bus. It also is made up of 32 Stream Processors, 16 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce 825M should theoretically be a small bit faster than the GeForce 8600 GT 256MB DDR2 in general. (explain)
Texel RateThe GeForce 825M is a lot (approximately 57%) faster with regards to anisotropic filtering than the GeForce 8600 GT 256MB DDR2. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce 825M is superior to the GeForce 8600 GT 256MB DDR2, by a large margin. (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 transported across the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill 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.
