Compare any two graphics cards:
GeForce 820M vs GeForce 9600 GSO ASUS 512
IntroThe GeForce 820M has a GPU core clock speed of 719 MHz, and the 2048 MB of DDR3 RAM is set to run at 1000 MHz through a 64-bit bus. It also is comprised of 96 Stream Processors, 16 TAUs, and 4 ROPs.Compare that to the GeForce 9600 GSO ASUS 512, which uses a 65 nm design. nVidia has clocked the core speed at 550 MHz. The DDR2 RAM is set to run at a frequency of 500 MHz on this model. It features 96 SPUs along with 48 Texture Address Units and 12 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have exactly the same memory bandwidth, so in theory they should perform the same. (explain)
Texel RateThe GeForce 9600 GSO ASUS 512 is much (about 129%) better at texture filtering than the GeForce 820M. (explain)
Pixel RateThe GeForce 9600 GSO ASUS 512 should be a lot (approximately 129%) faster with regards to anti-aliasing than the GeForce 820M, and also will be capable of handling higher screen resolutions while still performing well. (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 data (in units of megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record 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 - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
