GeForce 8800 GT 512MB vs GeForce 930M

Intro

Compare those specifications to the GeForce 930M, which comes with GPU core speed of 928 MHz, and 2048 MB of DDR3 RAM running at 900 MHz through a 64-bit bus. It also is comprised of 384 Stream Processors, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce 8800 GT 512MB should theoretically be quite a bit superior to the GeForce 930M in general. (explain)

GeForce 8800 GT 512MB		57600 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 43200 (300%)

Texel Rate

The GeForce 8800 GT 512MB should be quite a bit (more or less 51%) faster with regards to texture filtering than the GeForce 930M. (explain)

GeForce 8800 GT 512MB		33600 Mtexels/sec
GeForce 930M		22272 Mtexels/sec
	Difference: 11328 (51%)

Pixel Rate

The GeForce 8800 GT 512MB is a lot (more or less 29%) better at anti-aliasing than the GeForce 930M, and also should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce 8800 GT 512MB		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 max amount of information (measured in MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the bus 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 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
