GeForce 8600 GT 512MB DDR2 vs Geforce GTX 760

Intro

Compare all that to the Geforce GTX 760, which features GPU core speed of 980 MHz, and 2048 MB of GDDR5 RAM running at 1502 MHz through a 256-bit bus. It also is made up of 1152 SPUs, 96 Texture Address Units, and 32 Raster Operation Units.

GeForce 8600 GT 512MB DDR2		47 Watts
Geforce GTX 760		170 Watts
	Difference: 123 Watts (262%)

Memory Bandwidth

As far as performance goes, the Geforce GTX 760 should theoretically be a lot superior to the GeForce 8600 GT 512MB DDR2 in general. (explain)

Geforce GTX 760		192256 MB/sec
GeForce 8600 GT 512MB DDR2		12800 MB/sec
	Difference: 179456 (1402%)

Texel Rate

The Geforce GTX 760 should be a lot (more or less 989%) better at anisotropic filtering than the GeForce 8600 GT 512MB DDR2. (explain)

Geforce GTX 760		94080 Mtexels/sec
GeForce 8600 GT 512MB DDR2		8640 Mtexels/sec
	Difference: 85440 (989%)

Pixel Rate

If using high levels of AA is important to you, then the Geforce GTX 760 is superior to the GeForce 8600 GT 512MB DDR2, and very much so. (explain)

Geforce GTX 760		31360 Mpixels/sec
GeForce 8600 GT 512MB DDR2		4320 Mpixels/sec
	Difference: 27040 (626%)

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 max amount of data (measured in MB per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 number of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines 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 fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
