GeForce 8600 GT 512MB GDDR3 vs GeForce GTX 570

Intro

Compare all of that to the GeForce GTX 570, which has core clock speeds of 732 MHz on the GPU, and 950 MHz on the 1280 MB of GDDR5 memory. It features 480 SPUs as well as 60 TAUs and 40 ROPs.

GeForce 8600 GT 512MB GDDR3		47 Watts
GeForce GTX 570		219 Watts
	Difference: 172 Watts (366%)

Memory Bandwidth

The GeForce GTX 570 should in theory perform quite a bit faster than the GeForce 8600 GT 512MB GDDR3 in general. (explain)

GeForce GTX 570		152000 MB/sec
GeForce 8600 GT 512MB GDDR3		22400 MB/sec
	Difference: 129600 (579%)

Texel Rate

The GeForce GTX 570 should be a lot (approximately 408%) faster with regards to texture filtering than the GeForce 8600 GT 512MB GDDR3. (explain)

GeForce GTX 570		43920 Mtexels/sec
GeForce 8600 GT 512MB GDDR3		8640 Mtexels/sec
	Difference: 35280 (408%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 570 is superior to the GeForce 8600 GT 512MB GDDR3, and very much so. (explain)

GeForce GTX 570		29280 Mpixels/sec
GeForce 8600 GT 512MB GDDR3		4320 Mpixels/sec
	Difference: 24960 (578%)

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 maximum amount of data (measured in MB per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, 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 in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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