GeForce 8600 GT 1GB GDDR3 vs GeForce GTX Titan X

Intro

Compare all of that to the GeForce GTX Titan X, which makes use of a 28 nm design. nVidia has set the core frequency at 1000 MHz. The GDDR5 RAM works at a speed of 1750 MHz on this specific card. It features 3072 SPUs as well as 192 Texture Address Units and 96 Rasterization Operator Units.

GeForce 8600 GT 1GB GDDR3		22400 MB/sec
	Difference: 313600 (1400%)

Texel Rate

The GeForce GTX Titan X will be quite a bit (approximately 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, by a large margin. (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 information (in units of MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video 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 could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units 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 rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
