GeForce 8600 GT 1GB GDDR3 vs GeForce GTX Titan Black

Intro

Compare all of that to the GeForce GTX Titan Black, which comes with core speeds of 889 MHz on the GPU, and 1750 MHz on the 6144 MB of GDDR5 memory. It features 2880 SPUs as well as 240 TAUs and 48 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GT 1GB GDDR3		47 Watts
GeForce GTX Titan Black		250 Watts
	Difference: 203 Watts (432%)

Memory Bandwidth

In theory, the GeForce GTX Titan Black is 1400% quicker than the GeForce 8600 GT 1GB GDDR3 overall, because of its higher bandwidth. (explain)

GeForce GTX Titan Black		336000 MB/sec
GeForce 8600 GT 1GB GDDR3		22400 MB/sec
	Difference: 313600 (1400%)

Texel Rate

The GeForce GTX Titan Black is a lot (about 2369%) more effective at anisotropic filtering than the GeForce 8600 GT 1GB GDDR3. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
GeForce 8600 GT 1GB GDDR3		8640 Mtexels/sec
	Difference: 204720 (2369%)

Pixel Rate

The GeForce GTX Titan Black is quite a bit (more or less 888%) more effective at anti-aliasing than the GeForce 8600 GT 1GB GDDR3, and also capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX Titan Black		42672 Mpixels/sec
GeForce 8600 GT 1GB GDDR3		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 max amount of data (counted in MB per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is calculated 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 applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
