GeForce 8600 GT 1GB GDDR3 vs GeForce GTX Titan

Intro

Compare all that to the GeForce GTX Titan, which uses a 28 nm design. nVidia has clocked the core frequency at 837 MHz. The GDDR5 RAM runs at a frequency of 1502 MHz on this particular card. It features 2688 SPUs as well as 224 TAUs and 48 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the GeForce GTX Titan will be 1187% faster than the GeForce 8600 GT 1GB GDDR3 in general, due to its greater data rate. (explain)

GeForce GTX Titan		288384 MB/sec
GeForce 8600 GT 1GB GDDR3		22400 MB/sec
	Difference: 265984 (1187%)

Texel Rate

The GeForce GTX Titan is quite a bit (more or less 2070%) faster with regards to texture filtering than the GeForce 8600 GT 1GB GDDR3. (explain)

GeForce GTX Titan		187488 Mtexels/sec
GeForce 8600 GT 1GB GDDR3		8640 Mtexels/sec
	Difference: 178848 (2070%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX Titan is a better choice, and very much so. (explain)

GeForce GTX Titan		40176 Mpixels/sec
GeForce 8600 GT 1GB GDDR3		4320 Mpixels/sec
	Difference: 35856 (830%)

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 largest amount of data (counted in MB per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics 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 ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
