GeForce 8600 GS (OEM) vs GeForce GT 130

Intro

Compare all that 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 TAUs, and 16 Raster Operation Units.

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

Memory Bandwidth

Theoretically speaking, the GeForce 8600 GS (OEM) should be 7% faster than the GeForce GT 130 in general, due to its higher data rate. (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 (approximately 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

The GeForce GT 130 will be much (approximately 85%) better at AA than the GeForce 8600 GS (OEM), and also should be able to handle higher resolutions better. (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 largest amount of information (in units of MB per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units 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 one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
