GeForce 8600 GS (OEM) vs GeForce GTX 465

Intro

Compare those specs to the GeForce GTX 465, which makes use of a 40 nm design. nVidia has clocked the core speed at 607 MHz. The GDDR5 RAM is set to run at a frequency of 802 MHz on this model. It features 352 SPUs as well as 44 TAUs and 32 ROPs.

Texel Rate

The GeForce GTX 465 should be quite a bit (more or less 209%) faster with regards to anisotropic filtering than the GeForce 8600 GS (OEM). (explain)

GeForce GTX 465		26708 Mtexels/sec
GeForce 8600 GS (OEM)		8640 Mtexels/sec
	Difference: 18068 (209%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 465 is superior to the GeForce 8600 GS (OEM), by far. (explain)

GeForce GTX 465		19424 Mpixels/sec
GeForce 8600 GS (OEM)		4320 Mpixels/sec
	Difference: 15104 (350%)

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 information (in units of megabytes per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number 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 applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
