GeForce 8600 GT 1GB GDDR3 vs GeForce GTX Titan X

Intro

Compare those specs to the GeForce GTX Titan X, which comes with core clock speeds of 1000 MHz on the GPU, and 1750 MHz on the 12288 MB of GDDR5 memory. It features 3072 SPUs along with 192 TAUs and 96 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

As far as performance goes, the GeForce GTX Titan X should in theory be much superior to the GeForce 8600 GT 1GB GDDR3 in general. (explain)

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

Texel Rate

The GeForce GTX Titan X should be a lot (approximately 2122%) better at anisotropic filtering 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 running with lots of anti-aliasing is important to you, then the GeForce GTX Titan X is superior to the GeForce 8600 GT 1GB GDDR3, and very much so. (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: Bandwidth is the max amount of data (measured in MB per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. 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 output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
