Compare any two graphics cards:
GeForce 825M vs GeForce GT 310
IntroThe GeForce 825M features clock speeds of 850 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 384 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.Compare those specifications to the GeForce GT 310, which has core clock speeds of 589 MHz on the GPU, and 1000 MHz on the 512 MB of DDR2 memory. It features 16 SPUs as well as 8 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GT 310 is 11% faster than the GeForce 825M in general, because of its greater data rate. (explain)
Texel RateThe GeForce 825M is a lot (more or less 189%) faster with regards to texture filtering than the GeForce GT 310. (explain)
Pixel RateThe GeForce 825M will be a lot (more or less 189%) faster with regards to FSAA than the GeForce GT 310, and also should be capable of handling higher resolutions without losing too much performance. (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 information (in units of megabytes per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number 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 in a second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
