GeForce 830M		14400 MB/sec
	Difference: 43200 (300%)

Texel Rate

The GeForce 8800 GT 512MB should be a lot (about 104%) faster with regards to anisotropic filtering than the GeForce 830M. (explain)

GeForce 8800 GT 512MB		33600 Mtexels/sec
GeForce 830M		16464 Mtexels/sec
	Difference: 17136 (104%)

Pixel Rate

The GeForce 8800 GT 512MB is just a bit (more or less 17%) faster with regards to anti-aliasing than the GeForce 830M, and also should be able to handle higher resolutions while still performing well. (explain)

GeForce 8800 GT 512MB		9600 Mpixels/sec
GeForce 830M		8232 Mpixels/sec
	Difference: 1368 (17%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
