GeForce 8600 GT 1GB GDDR3 vs GeForce GTX Titan X

Intro

Compare all of that to the GeForce GTX Titan X, which comes with GPU clock speed of 1000 MHz, and 12288 MB of GDDR5 RAM running at 1750 MHz through a 384-bit bus. It also features 3072 Stream Processors, 192 Texture Address Units, and 96 ROPs.

Texel Rate

The GeForce GTX Titan X will be a lot (about 2122%) more effective at AF than the GeForce 8600 GT 1GB GDDR3. (explain)

GeForce GTX Titan X		192000 Mtexels/sec
GeForce 8600 GT 1GB GDDR3		8640 Mtexels/sec
	Difference: 183360 (2122%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX Titan X is the winner, and very much so. (explain)

GeForce GTX Titan X		96000 Mpixels/sec
GeForce 8600 GT 1GB GDDR3		4320 Mpixels/sec
	Difference: 91680 (2122%)

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 data (measured in MB per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is worked out 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 processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
