GeForce 9600 GSO 768MB vs GeForce GTX 780 Ti

Intro

Compare that to the GeForce GTX 780 Ti, which features GPU clock speed of 875 MHz, and 3072 MB of GDDR5 memory set to run at 1750 MHz through a 384-bit bus. It also is made up of 2880 SPUs, 240 Texture Address Units, and 48 ROPs.

In theory, the GeForce GTX 780 Ti should be 775% quicker than the GeForce 9600 GSO 768MB in general, due to its higher bandwidth. (explain)

GeForce GTX 780 Ti		336000 MB/sec
GeForce 9600 GSO 768MB		38400 MB/sec
	Difference: 297600 (775%)

Texel Rate

The GeForce GTX 780 Ti will be quite a bit (about 695%) faster with regards to AF than the GeForce 9600 GSO 768MB. (explain)

GeForce GTX 780 Ti		210000 Mtexels/sec
GeForce 9600 GSO 768MB		26400 Mtexels/sec
	Difference: 183600 (695%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 780 Ti is the winner, by far. (explain)

GeForce GTX 780 Ti		42000 Mpixels/sec
GeForce 9600 GSO 768MB		6600 Mpixels/sec
	Difference: 35400 (536%)

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 largest amount of information (measured in MB per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster 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 number of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units 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 processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few 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.
