GeForce 8600 GS (OEM) vs GeForce GT 130

Intro

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

Memory Bandwidth

The GeForce 8600 GS (OEM) should theoretically perform a small 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 is quite a bit (more or less 39%) faster with regards to texture 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 high levels of AA is important to you, then the GeForce GT 130 is a better choice, 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: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 are processed in one 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
