GeForce 8600 GS (OEM) vs GeForce GTX Titan

Intro

Compare all of that to the GeForce GTX Titan, which uses a 28 nm design. nVidia has set the core frequency at 837 MHz. The GDDR5 memory runs at a frequency of 1502 MHz on this model. It features 2688 SPUs as well as 224 Texture Address Units and 48 ROPs.

GeForce 8600 GS (OEM)		47 Watts
GeForce GTX Titan		250 Watts
	Difference: 203 Watts (432%)

Memory Bandwidth

Performance-wise, the GeForce GTX Titan should in theory be quite a bit superior to the GeForce 8600 GS (OEM) overall. (explain)

GeForce GTX Titan		288384 MB/sec
GeForce 8600 GS (OEM)		12800 MB/sec
	Difference: 275584 (2153%)

Texel Rate

The GeForce GTX Titan will be a lot (more or less 2070%) better at AF than the GeForce 8600 GS (OEM). (explain)

GeForce GTX Titan		187488 Mtexels/sec
GeForce 8600 GS (OEM)		8640 Mtexels/sec
	Difference: 178848 (2070%)

Pixel Rate

The GeForce GTX Titan is a lot (more or less 830%) faster with regards to FSAA than the GeForce 8600 GS (OEM), and should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX Titan		40176 Mpixels/sec
GeForce 8600 GS (OEM)		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: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
