GeForce 8600 GT 1GB DDR2 vs Nvidia Titan X

Intro

Compare those specs to the Nvidia Titan X, which has a clock speed of 1417 MHz and a GDDR5X memory speed of 1251 MHz. It also uses a 384-bit bus, and makes use of a 16 nm design. It is made up of 3584 SPUs, 224 Texture Address Units, and 96 Raster Operation Units.

GeForce 8600 GT 1GB DDR2		47 Watts
Nvidia Titan X		250 Watts
	Difference: 203 Watts (432%)

Memory Bandwidth

In theory, the Nvidia Titan X should be much faster than the GeForce 8600 GT 1GB DDR2 overall. (explain)

Nvidia Titan X		491520 MB/sec
GeForce 8600 GT 1GB DDR2		12800 MB/sec
	Difference: 478720 (3740%)

Texel Rate

The Nvidia Titan X is much (more or less 3574%) more effective at anisotropic filtering than the GeForce 8600 GT 1GB DDR2. (explain)

Nvidia Titan X		317408 Mtexels/sec
GeForce 8600 GT 1GB DDR2		8640 Mtexels/sec
	Difference: 308768 (3574%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Nvidia Titan X is a better choice, by a large margin. (explain)

Nvidia Titan X		136032 Mpixels/sec
GeForce 8600 GT 1GB DDR2		4320 Mpixels/sec
	Difference: 131712 (3049%)

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 (in units of MB per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
