GeForce 8800 GT 512MB vs GeForce GTX Titan

Intro

Compare those specs to the GeForce GTX Titan, which uses a 28 nm design. nVidia has clocked the core speed at 837 MHz. The GDDR5 RAM is set to run at a frequency of 1502 MHz on this card. It features 2688 SPUs along with 224 Texture Address Units and 48 Rasterization Operator Units.

GeForce 8800 GT 512MB		105 Watts
GeForce GTX Titan		250 Watts
	Difference: 145 Watts (138%)

Memory Bandwidth

As far as performance goes, the GeForce GTX Titan should in theory be a lot better than the GeForce 8800 GT 512MB in general. (explain)

GeForce GTX Titan		288384 MB/sec
GeForce 8800 GT 512MB		57600 MB/sec
	Difference: 230784 (401%)

Texel Rate

The GeForce GTX Titan is quite a bit (more or less 458%) more effective at texture filtering than the GeForce 8800 GT 512MB. (explain)

GeForce GTX Titan		187488 Mtexels/sec
GeForce 8800 GT 512MB		33600 Mtexels/sec
	Difference: 153888 (458%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX Titan is superior to the GeForce 8800 GT 512MB, by a large margin. (explain)

GeForce GTX Titan		40176 Mpixels/sec
GeForce 8800 GT 512MB		9600 Mpixels/sec
	Difference: 30576 (319%)

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 megabytes per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of 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 higher this number, the better the 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 maximum number of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
