GeForce 8600 GTS vs GeForce GTX Titan Black

Intro

Compare that to the GeForce GTX Titan Black, which has a clock speed of 889 MHz and a GDDR5 memory frequency of 1750 MHz. It also makes use of a 384-bit memory bus, and uses a 28 nm design. It features 2880 SPUs, 240 TAUs, and 48 ROPs.

GeForce 8600 GTS		32000 MB/sec
	Difference: 304000 (950%)

Texel Rate

The GeForce GTX Titan Black is much (about 1876%) better at anisotropic filtering than the GeForce 8600 GTS. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
GeForce 8600 GTS		10800 Mtexels/sec
	Difference: 202560 (1876%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX Titan Black is the winner, by far. (explain)

GeForce GTX Titan Black		42672 Mpixels/sec
GeForce 8600 GTS		5400 Mpixels/sec
	Difference: 37272 (690%)

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 max amount of data (counted in MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range 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 calculated by multiplying the total number of 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 applied per second.

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