GeForce 9600 GT 1GB vs Geforce GTX 780

Intro

Compare all of that to the Geforce GTX 780, which uses a 28 nm design. nVidia has set the core frequency at 863 MHz. The GDDR5 memory works at a frequency of 1502 MHz on this card. It features 2304 SPUs as well as 192 Texture Address Units and 48 ROPs.

GeForce 9600 GT 1GB		20800 Mtexels/sec
	Difference: 144896 (697%)

Pixel Rate

The Geforce GTX 780 will be quite a bit (approximately 298%) more effective at AA than the GeForce 9600 GT 1GB, and also able to handle higher resolutions better. (explain)

Geforce GTX 780		41424 Mpixels/sec
GeForce 9600 GT 1GB		10400 Mpixels/sec
	Difference: 31024 (298%)

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 (measured in MB per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total number of texture units by the core clock 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 a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate 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 filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
