GeForce 8800 Ultra vs GeForce 930M

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 8800 Ultra, in theory, should perform much faster than the GeForce 930M in general. (explain)

GeForce 8800 Ultra		103680 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 89280 (620%)

Texel Rate

The GeForce 8800 Ultra is a lot (about 76%) better at AF than the GeForce 930M. (explain)

GeForce 8800 Ultra		39168 Mtexels/sec
GeForce 930M		22272 Mtexels/sec
	Difference: 16896 (76%)

Pixel Rate

The GeForce 8800 Ultra should be a lot (more or less 98%) more effective at anti-aliasing than the GeForce 930M, and also should be capable of handling higher resolutions more effectively. (explain)

GeForce 8800 Ultra		14688 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 7264 (98%)

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 max amount of data (counted in MB per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, 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 is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, 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 maximum number of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
