GeForce 8600 GS (OEM) vs GeForce GT 130

Intro

Compare those specs to the GeForce GT 130, which comes with a clock speed of 500 MHz and a DDR2 memory speed of 250 MHz. It also features a 192-bit bus, and makes use of a 55 nm design. It features 48 SPUs, 24 Texture Address Units, and 16 Raster Operation Units.

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

In theory, the GeForce 8600 GS (OEM) should perform just a bit faster than the GeForce GT 130 overall. (explain)

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

Texel Rate

The GeForce GT 130 will be quite a bit (approximately 39%) more effective 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 running with a high screen resolution is important to you, then the GeForce GT 130 is the winner, by far. (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 largest amount of data (measured in MB per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 processed per second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
