Compare any two graphics cards:
GeForce 825M vs GeForce GT 130
IntroThe GeForce 825M features a GPU core clock speed of 850 MHz, and the 2048 MB of DDR3 RAM is set to run at 900 MHz through a 64-bit bus. It also features 384 SPUs, 16 TAUs, and 8 Raster Operation Units.Compare those specifications to the GeForce GT 130, which comes with GPU core speed of 500 MHz, and 768 MB of DDR2 RAM running at 250 MHz through a 192-bit bus. It also features 48 SPUs, 24 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce 825M should theoretically be a small bit faster than the GeForce GT 130 overall. (explain)
Texel RateThe GeForce 825M is a small bit (more or less 13%) faster with regards to anisotropic filtering than the GeForce GT 130. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GT 130 is the winner, but only just. (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 MB per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 once 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 anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
