Compare any two graphics cards:
GeForce 820M vs GeForce 9600 GSO ASUS 512
IntroThe GeForce 820M features core speeds of 719 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 RAM. It features 96 SPUs along with 16 Texture Address Units and 4 ROPs.Compare those specs to the GeForce 9600 GSO ASUS 512, which has clock speeds of 550 MHz on the GPU, and 500 MHz on the 512 MB of DDR2 memory. It features 96 SPUs as well as 48 Texture Address Units and 12 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have the exact same memory bandwidth, so theoretically they should have identical performance. (explain)
Texel RateThe GeForce 9600 GSO ASUS 512 should be much (more or less 129%) faster with regards to anisotropic filtering than the GeForce 820M. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce 9600 GSO ASUS 512 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 information (measured in megabytes per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 texture map elements (texels) that are applied in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
