GeForce 8800 GT 1GB vs GeForce 930M

Intro

Compare all that to the GeForce 930M, which features a GPU core clock speed of 928 MHz, and 2048 MB of DDR3 RAM set to run at 900 MHz through a 64-bit bus. It also is comprised of 384 Stream Processors, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 8800 GT 1GB should be 300% quicker than the GeForce 930M overall, due to its higher bandwidth. (explain)

GeForce 8800 GT 1GB		57600 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 43200 (300%)

Texel Rate

The GeForce 8800 GT 1GB will be quite a bit (approximately 51%) better at anisotropic filtering than the GeForce 930M. (explain)

GeForce 8800 GT 1GB		33600 Mtexels/sec
GeForce 930M		22272 Mtexels/sec
	Difference: 11328 (51%)

Pixel Rate

The GeForce 8800 GT 1GB should be much (about 29%) better at anti-aliasing than the GeForce 930M, and also will be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce 8800 GT 1GB		9600 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 2176 (29%)

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 largest amount of information (measured in megabytes per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

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