GeForce 9600 GSO 768MB vs Geforce GTX 780

Intro

Compare those specifications to the Geforce GTX 780, which comes with GPU clock speed of 863 MHz, and 3072 MB of GDDR5 memory 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 9600 GSO 768MB		38400 MB/sec
	Difference: 249984 (651%)

Texel Rate

The Geforce GTX 780 is a lot (approximately 528%) better at texture filtering than the GeForce 9600 GSO 768MB. (explain)

Geforce GTX 780		165696 Mtexels/sec
GeForce 9600 GSO 768MB		26400 Mtexels/sec
	Difference: 139296 (528%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Geforce GTX 780 is a better choice, and very much so. (explain)

Geforce GTX 780		41424 Mpixels/sec
GeForce 9600 GSO 768MB		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 data (counted in megabytes per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the bus width by its memory 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 bandwidth is, 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 applied in one second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
