GeForce 8600 GT 512MB GDDR3 vs Nvidia Titan X

Intro

Compare those specs to the Nvidia Titan X, which has a core clock frequency of 1417 MHz and a GDDR5X memory frequency 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 512MB GDDR3		22400 MB/sec
	Difference: 469120 (2094%)

Texel Rate

The Nvidia Titan X should be quite a bit (about 3574%) faster with regards to texture filtering than the GeForce 8600 GT 512MB GDDR3. (explain)

Nvidia Titan X		317408 Mtexels/sec
GeForce 8600 GT 512MB GDDR3		8640 Mtexels/sec
	Difference: 308768 (3574%)

Pixel Rate

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

GeForce 8600 GT 512MB GDDR3		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 (counted in megabytes per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
