Compare any two graphics cards:
GeForce 820M vs GeForce 8800 GS
IntroThe GeForce 820M comes with 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 Rasterization Operator Units.Compare those specifications to the GeForce 8800 GS, which comes with GPU clock speed of 550 MHz, and 384 MB of GDDR3 RAM running at 800 MHz through a 192-bit bus. It also is comprised of 96 SPUs, 48 TAUs, and 12 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce 8800 GS should in theory be quite a bit better than the GeForce 820M in general. (explain)
Texel RateThe GeForce 8800 GS should be a lot (more or less 129%) better at texture filtering than the GeForce 820M. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce 8800 GS is a better choice, by far. (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 maximum amount of information (counted in MB per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once 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 AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
