GeForce 8800 GTX vs GeForce GTX Titan

Intro

Compare those specifications to the GeForce GTX Titan, which comes with GPU clock speed of 837 MHz, and 6144 MB of GDDR5 memory set to run at 1502 MHz through a 384-bit bus. It also is made up of 2688 Stream Processors, 224 TAUs, and 48 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GTX		155 Watts
GeForce GTX Titan		250 Watts
	Difference: 95 Watts (61%)

Memory Bandwidth

The GeForce GTX Titan should in theory perform quite a bit faster than the GeForce 8800 GTX in general. (explain)

GeForce GTX Titan		288384 MB/sec
GeForce 8800 GTX		86400 MB/sec
	Difference: 201984 (234%)

Texel Rate

The GeForce GTX Titan should be a lot (more or less 409%) faster with regards to AF than the GeForce 8800 GTX. (explain)

GeForce GTX Titan		187488 Mtexels/sec
GeForce 8800 GTX		36800 Mtexels/sec
	Difference: 150688 (409%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX Titan is a better choice, by a large margin. (explain)

GeForce GTX Titan		40176 Mpixels/sec
GeForce 8800 GTX		13800 Mpixels/sec
	Difference: 26376 (191%)

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 maximum amount of information (counted in MB per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 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 number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in one 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 outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
