GeForce 8800 GT 256MB vs GeForce GTX Titan Black

Intro

Compare all of that to the GeForce GTX Titan Black, which comes with GPU clock speed of 889 MHz, and 6144 MB of GDDR5 RAM running at 1750 MHz through a 384-bit bus. It also features 2880 SPUs, 240 TAUs, and 48 Raster Operation Units.

Texel Rate

The GeForce GTX Titan Black will be much (more or less 535%) more effective at anisotropic filtering than the GeForce 8800 GT 256MB. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
GeForce 8800 GT 256MB		33600 Mtexels/sec
	Difference: 179760 (535%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX Titan Black is superior to the GeForce 8800 GT 256MB, and very much so. (explain)

GeForce GTX Titan Black		42672 Mpixels/sec
GeForce 8800 GT 256MB		9600 Mpixels/sec
	Difference: 33072 (345%)

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 maximum amount of information (counted in megabytes per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
