GeForce 9600 GT 1GB vs Geforce GTX 670

Intro

Compare all of that to the Geforce GTX 670, which uses a 28 nm design. nVidia has set the core speed at 915 MHz. The GDDR5 memory works at a frequency of 1500 MHz on this particular model. It features 1344 SPUs along with 112 Texture Address Units and 32 Rasterization Operator Units.

	Difference: 134400 (233%)

Texel Rate

The Geforce GTX 670 is quite a bit (more or less 393%) faster with regards to texture filtering than the GeForce 9600 GT 1GB. (explain)

Geforce GTX 670		102480 Mtexels/sec
GeForce 9600 GT 1GB		20800 Mtexels/sec
	Difference: 81680 (393%)

Pixel Rate

The Geforce GTX 670 is quite a bit (more or less 182%) faster with regards to AA than the GeForce 9600 GT 1GB, and also will be capable of handling higher screen resolutions while still performing well. (explain)

Geforce GTX 670		29280 Mpixels/sec
GeForce 9600 GT 1GB		10400 Mpixels/sec
	Difference: 18880 (182%)

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 maximum amount of data (measured in MB per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics 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 can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
