GeForce 9600 GT 1GB vs Geforce GTX 780

Intro

Compare those specifications to the Geforce GTX 780, which uses a 28 nm design. nVidia has clocked the core speed at 863 MHz. The GDDR5 memory is set to run at a frequency of 1502 MHz on this specific card. It features 2304 SPUs along with 192 Texture Address Units and 48 Rasterization Operator Units.

The Geforce GTX 780 is quite a bit (more or less 697%) more effective at anisotropic filtering than the GeForce 9600 GT 1GB. (explain)

Geforce GTX 780		165696 Mtexels/sec
GeForce 9600 GT 1GB		20800 Mtexels/sec
	Difference: 144896 (697%)

Pixel Rate

The Geforce GTX 780 will be much (approximately 298%) more effective at full screen anti-aliasing than the GeForce 9600 GT 1GB, and also will be capable of handling 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: Bandwidth is the largest amount of information (measured in MB per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
