GeForce 8800 GT 256MB vs GeForce 920M

Intro

Compare that to the GeForce 920M, which comes with a GPU core clock speed of 954 MHz, and 2048 MB of DDR3 RAM set to run at 900 MHz through a 64-bit bus. It also is made up of 384 SPUs, 32 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 8800 GT 256MB should perform a lot faster than the GeForce 920M in general. (explain)

GeForce 8800 GT 256MB		44800 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 30400 (211%)

Texel Rate

The GeForce 8800 GT 256MB is a little bit (approximately 10%) faster with regards to texture filtering than the GeForce 920M. (explain)

GeForce 8800 GT 256MB		33600 Mtexels/sec
GeForce 920M		30528 Mtexels/sec
	Difference: 3072 (10%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce 8800 GT 256MB is superior to the GeForce 920M, and very much so. (explain)

GeForce 8800 GT 256MB		9600 Mpixels/sec
GeForce 920M		7632 Mpixels/sec
	Difference: 1968 (26%)

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: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 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 AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at 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 the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to 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 ability to get to the max fill rate.
