GeForce 8800 GS vs GeForce GTX Titan

Intro

Compare all that to the GeForce GTX Titan, which features a clock speed of 837 MHz and a GDDR5 memory speed of 1502 MHz. It also features a 384-bit bus, and makes use of a 28 nm design. It is made up of 2688 SPUs, 224 TAUs, and 48 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GS		105 Watts
GeForce GTX Titan		250 Watts
	Difference: 145 Watts (138%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX Titan should perform a lot faster than the GeForce 8800 GS overall. (explain)

GeForce GTX Titan		288384 MB/sec
GeForce 8800 GS		38400 MB/sec
	Difference: 249984 (651%)

Texel Rate

The GeForce GTX Titan will be a lot (more or less 610%) faster with regards to texture filtering than the GeForce 8800 GS. (explain)

GeForce GTX Titan		187488 Mtexels/sec
GeForce 8800 GS		26400 Mtexels/sec
	Difference: 161088 (610%)

Pixel Rate

The GeForce GTX Titan should be quite a bit (about 509%) more effective at AA than the GeForce 8800 GS, and also should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX Titan		40176 Mpixels/sec
GeForce 8800 GS		6600 Mpixels/sec
	Difference: 33576 (509%)

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 (in units of MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
