GeForce 8600 GTS vs GeForce GTX Titan

Intro

Compare all that to the GeForce GTX Titan, which has a clock speed of 837 MHz and a GDDR5 memory frequency of 1502 MHz. It also features a 384-bit bus, and uses a 28 nm design. It is made up of 2688 SPUs, 224 TAUs, and 48 Raster Operation Units.

GeForce 8600 GTS		32000 MB/sec
	Difference: 256384 (801%)

Texel Rate

The GeForce GTX Titan will be much (about 1636%) more effective at texture filtering than the GeForce 8600 GTS. (explain)

GeForce GTX Titan		187488 Mtexels/sec
GeForce 8600 GTS		10800 Mtexels/sec
	Difference: 176688 (1636%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX Titan is the winner, and very much so. (explain)

GeForce GTX Titan		40176 Mpixels/sec
GeForce 8600 GTS		5400 Mpixels/sec
	Difference: 34776 (644%)

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 (in units of MB per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher 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 processed per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
