GeForce 8800 GTS (G80) 320MB vs GeForce 930M

Intro

Compare all of that to the GeForce 930M, which makes use of a 28 nm design. nVidia has set the core frequency at 928 MHz. The DDR3 RAM is set to run at a frequency of 900 MHz on this particular model. It features 384 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 8800 GTS (G80) 320MB, in theory, should be much faster than the GeForce 930M in general. (explain)

GeForce 8800 GTS (G80) 320MB		63360 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 48960 (340%)

Texel Rate

The GeForce 8800 GTS (G80) 320MB is a bit (about 11%) faster with regards to anisotropic filtering than the GeForce 930M. (explain)

GeForce 8800 GTS (G80) 320MB		24624 Mtexels/sec
GeForce 930M		22272 Mtexels/sec
	Difference: 2352 (11%)

Pixel Rate

The GeForce 8800 GTS (G80) 320MB will be a lot (more or less 38%) better at anti-aliasing than the GeForce 930M, and should be able to handle higher resolutions without slowing down too much. (explain)

GeForce 8800 GTS (G80) 320MB		10260 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 2836 (38%)

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 (measured in MB per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR memory, it must 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the 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 graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
