GeForce 9600 GSO 1.5GB vs Geforce GTX 780

Intro

Compare all of that to the Geforce GTX 780, which has GPU clock speed of 863 MHz, and 3072 MB of GDDR5 RAM set to run at 1502 MHz through a 384-bit bus. It also is comprised of 2304 SPUs, 192 Texture Address Units, and 48 Raster Operation Units.

Geforce GTX 780		288384 MB/sec
GeForce 9600 GSO 1.5GB		38400 MB/sec
	Difference: 249984 (651%)

Texel Rate

The Geforce GTX 780 will be a lot (about 528%) better at anisotropic filtering than the GeForce 9600 GSO 1.5GB. (explain)

Geforce GTX 780		165696 Mtexels/sec
GeForce 9600 GSO 1.5GB		26400 Mtexels/sec
	Difference: 139296 (528%)

Pixel Rate

If using high levels of AA is important to you, then the Geforce GTX 780 is superior to the GeForce 9600 GSO 1.5GB, by far. (explain)

Geforce GTX 780		41424 Mpixels/sec
GeForce 9600 GSO 1.5GB		6600 Mpixels/sec
	Difference: 34824 (528%)

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 max amount of information (measured in megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the 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 amount of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes 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 memory bandwidth is, the lower the ability to reach the maximum fill rate.
