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

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce 825M should theoretically perform just a bit faster than the GeForce 8600 GT 1GB DDR2 in general. (explain)
Texel RateThe GeForce 825M should be much (approximately 57%) better at texture filtering than the GeForce 8600 GT 1GB DDR2. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce 825M 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: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units by the core clock 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 in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in one 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 - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
