GeForce 8600 GS (OEM) vs GeForce GT 130

Intro

Compare that to the GeForce GT 130, which features a GPU core clock speed of 500 MHz, and 768 MB of DDR2 memory set to run at 250 MHz through a 192-bit bus. It also is made up of 48 Stream Processors, 24 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GS (OEM)		47 Watts
GeForce GT 130		75 Watts
	Difference: 28 Watts (60%)

Memory Bandwidth

The GeForce 8600 GS (OEM), in theory, should be a small bit faster than the GeForce GT 130 in general. (explain)

GeForce 8600 GS (OEM)		12800 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 800 (7%)

Texel Rate

The GeForce GT 130 should be much (about 39%) better at anisotropic filtering than the GeForce 8600 GS (OEM). (explain)

GeForce GT 130		12000 Mtexels/sec
GeForce 8600 GS (OEM)		8640 Mtexels/sec
	Difference: 3360 (39%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GT 130 is a better choice, and very much so. (explain)

GeForce GT 130		8000 Mpixels/sec
GeForce 8600 GS (OEM)		4320 Mpixels/sec
	Difference: 3680 (85%)

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 (counted in MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses 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 higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also 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 - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
