Compare any two graphics cards:
GeForce 830M vs GeForce 8600 GT 1GB DDR2
IntroThe GeForce 830M makes use of a 28 nm design. nVidia has set the core frequency at 1029 MHz. The DDR3 RAM is set to run at a frequency of 900 MHz on this particular model. It features 256 SPUs along with 16 TAUs and 8 ROPs.Compare those specs to the GeForce 8600 GT 1GB DDR2, which uses a 80 nm design. nVidia has clocked the core speed at 540 MHz. The DDR2 memory is set to run at a frequency of 400 MHz on this specific card. It features 32 SPUs as well as 16 Texture Address Units and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce 830M should theoretically be a little bit better than the GeForce 8600 GT 1GB DDR2 in general. (explain)
Texel RateThe GeForce 830M should be quite a bit (about 91%) better at texture filtering than the GeForce 8600 GT 1GB DDR2. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce 830M is superior to the GeForce 8600 GT 1GB DDR2, 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: Bandwidth is the max amount of data (in units of MB per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the 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 number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock 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 fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
