GeForce 830M vs GeForce 8800 Ultra

Intro

Compare those specifications to the GeForce 8800 Ultra, which features a GPU core clock speed of 612 MHz, and 768 MB of GDDR3 RAM running at 1080 MHz through a 384-bit bus. It also is made up of 128 Stream Processors, 64 Texture Address Units, and 24 ROPs.

GeForce 830M		14400 MB/sec
	Difference: 89280 (620%)

Texel Rate

The GeForce 8800 Ultra is a lot (more or less 138%) better at texture filtering than the GeForce 830M. (explain)

GeForce 8800 Ultra		39168 Mtexels/sec
GeForce 830M		16464 Mtexels/sec
	Difference: 22704 (138%)

Pixel Rate

If using a high resolution is important to you, then the GeForce 8800 Ultra is the winner, by a large margin. (explain)

GeForce 8800 Ultra		14688 Mpixels/sec
GeForce 830M		8232 Mpixels/sec
	Difference: 6456 (78%)

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 data (in units of megabytes per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better 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 texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
