GeForce 8800 GTX vs GeForce GTX Titan Black

Intro

Compare that to the GeForce GTX Titan Black, which uses a 28 nm design. nVidia has clocked the core frequency at 889 MHz. The GDDR5 RAM works at a frequency of 1750 MHz on this card. It features 2880 SPUs as well as 240 Texture Address Units and 48 Rasterization Operator Units.

	Difference: 95 Watts (61%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX Titan Black should perform quite a bit faster than the GeForce 8800 GTX overall. (explain)

GeForce GTX Titan Black		336000 MB/sec
GeForce 8800 GTX		86400 MB/sec
	Difference: 249600 (289%)

Texel Rate

The GeForce GTX Titan Black is quite a bit (more or less 480%) better at anisotropic filtering than the GeForce 8800 GTX. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
GeForce 8800 GTX		36800 Mtexels/sec
	Difference: 176560 (480%)

Pixel Rate

The GeForce GTX Titan Black will be quite a bit (about 209%) better at AA than the GeForce 8800 GTX, and should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX Titan Black		42672 Mpixels/sec
GeForce 8800 GTX		13800 Mpixels/sec
	Difference: 28872 (209%)

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 max amount of information (in units of megabytes per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, 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 that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. 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 is also dependant 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.
