Compare any two graphics cards:
GeForce 830M vs GeForce 8600 GT 256MB GDDR3
IntroThe GeForce 830M comes with a GPU clock speed of 1029 MHz, and the 2048 MB of DDR3 memory runs at 900 MHz through a 64-bit bus. It also is comprised of 256 Stream Processors, 16 Texture Address Units, and 8 Raster Operation Units.Compare all of that to the GeForce 8600 GT 256MB GDDR3, which comes with a core clock speed of 540 MHz and a GDDR3 memory frequency of 700 MHz. It also makes use of a 128-bit bus, and uses a 80 nm design. It is made up of 32 SPUs, 16 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce 8600 GT 256MB GDDR3 should be 56% quicker than the GeForce 830M overall, because of its greater bandwidth. (explain)
Texel RateThe GeForce 830M is much (more or less 91%) more effective at anisotropic filtering than the GeForce 8600 GT 256MB GDDR3. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce 830M is a better choice, by a large margin. (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 largest amount of data (in units of MB per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the 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 number of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
