GeForce 8600 GS (OEM) vs GeForce 930M

Intro

Compare those specs to the GeForce 930M, which makes use of a 28 nm design. nVidia has clocked the core frequency at 928 MHz. The DDR3 memory is set to run at a frequency of 900 MHz on this specific model. It features 384 SPUs as well as 24 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 930M should theoretically be just a bit faster than the GeForce 8600 GS (OEM) in general. (explain)

GeForce 930M		14400 MB/sec
GeForce 8600 GS (OEM)		12800 MB/sec
	Difference: 1600 (13%)

Texel Rate

The GeForce 930M is much (approximately 158%) better at texture filtering than the GeForce 8600 GS (OEM). (explain)

GeForce 930M		22272 Mtexels/sec
GeForce 8600 GS (OEM)		8640 Mtexels/sec
	Difference: 13632 (158%)

Pixel Rate

The GeForce 930M should be much (more or less 72%) better at anti-aliasing than the GeForce 8600 GS (OEM), and should be capable of handling higher resolutions without slowing down too much. (explain)

GeForce 930M		7424 Mpixels/sec
GeForce 8600 GS (OEM)		4320 Mpixels/sec
	Difference: 3104 (72%)

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 (measured in megabytes per second) that can be transported past the external memory interface within a second. The number 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 it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs 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 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 ability to get to the maximum fill rate.
