GeForce 8800 GTS (G92) vs GeForce 920M

Intro

Compare that to the GeForce 920M, which has clock speeds of 954 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 384 SPUs as well as 32 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 8800 GTS (G92) should in theory be quite a bit faster than the GeForce 920M in general. (explain)

GeForce 8800 GTS (G92)		62080 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 47680 (331%)

Texel Rate

The GeForce 8800 GTS (G92) should be quite a bit (more or less 36%) faster with regards to texture filtering than the GeForce 920M. (explain)

GeForce 8800 GTS (G92)		41600 Mtexels/sec
GeForce 920M		30528 Mtexels/sec
	Difference: 11072 (36%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce 8800 GTS (G92) is the winner, and very much so. (explain)

GeForce 8800 GTS (G92)		10400 Mpixels/sec
GeForce 920M		7632 Mpixels/sec
	Difference: 2768 (36%)

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 largest amount of data (counted in megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is calculated 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
