GeForce 8600 GT 512MB DDR2 vs GeForce GTX Titan Black

Intro

Compare all that to the GeForce GTX Titan Black, which features a core clock frequency of 889 MHz and a GDDR5 memory frequency of 1750 MHz. It also features a 384-bit bus, and uses a 28 nm design. It is made up of 2880 SPUs, 240 TAUs, and 48 Raster Operation Units.

Texel Rate

The GeForce GTX Titan Black will be quite a bit (about 2369%) more effective at AF than the GeForce 8600 GT 512MB DDR2. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
GeForce 8600 GT 512MB DDR2		8640 Mtexels/sec
	Difference: 204720 (2369%)

Pixel Rate

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

GeForce GTX Titan Black		42672 Mpixels/sec
GeForce 8600 GT 512MB DDR2		4320 Mpixels/sec
	Difference: 38352 (888%)

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 information (measured in MB per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 can be processed in one second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
