GeForce 8600 GT 1GB DDR2 vs GeForce 930M

Intro

Compare those specs to the GeForce 930M, which has a core clock speed of 928 MHz and a DDR3 memory speed of 900 MHz. It also features a 64-bit bus, and uses a 28 nm design. It is comprised of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 930M should in theory be just a bit faster than the GeForce 8600 GT 1GB DDR2 in general. (explain)

GeForce 930M		14400 MB/sec
GeForce 8600 GT 1GB DDR2		12800 MB/sec
	Difference: 1600 (13%)

Texel Rate

The GeForce 930M will be much (more or less 158%) better at texture filtering than the GeForce 8600 GT 1GB DDR2. (explain)

GeForce 930M		22272 Mtexels/sec
GeForce 8600 GT 1GB DDR2		8640 Mtexels/sec
	Difference: 13632 (158%)

Pixel Rate

The GeForce 930M will be a lot (approximately 72%) faster with regards to full screen anti-aliasing than the GeForce 8600 GT 1GB DDR2, and should be able to handle higher resolutions while still performing well. (explain)

GeForce 930M		7424 Mpixels/sec
GeForce 8600 GT 1GB DDR2		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: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

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