Compare any two graphics cards:
GeForce 825M vs GeForce 8600 GT 1GB DDR2
IntroThe GeForce 825M has a clock speed of 850 MHz and a DDR3 memory frequency of 900 MHz. It also makes use of a 64-bit bus, and uses a 28 nm design. It features 384 SPUs, 16 Texture Address Units, and 8 ROPs.Compare that to the GeForce 8600 GT 1GB DDR2, which has a core clock speed of 540 MHz and a DDR2 memory frequency of 400 MHz. It also features a 128-bit bus, and makes use of a 80 nm design. It features 32 SPUs, 16 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce 825M should theoretically perform a little bit faster than the GeForce 8600 GT 1GB DDR2 overall. (explain)
Texel RateThe GeForce 825M will be a lot (more or less 57%) faster with regards to anisotropic filtering than the GeForce 8600 GT 1GB DDR2. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce 825M is superior to the GeForce 8600 GT 1GB 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 maximum amount of information (in units of megabytes per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 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 AA, 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 worked out by multiplying the total number of texture units 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 amount of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
