GeForce 9600 GSO 1.5GB vs GeForce GTX 660 Ti

Intro

Compare all of that to the GeForce GTX 660 Ti, which features core clock speeds of 915 MHz on the GPU, and 1500 MHz on the 2048 MB of GDDR5 RAM. It features 1344 SPUs along with 112 TAUs and 24 Rasterization Operator Units.

The GeForce GTX 660 Ti will be a lot (approximately 288%) better at anisotropic filtering than the GeForce 9600 GSO 1.5GB. (explain)

GeForce GTX 660 Ti		102480 Mtexels/sec
GeForce 9600 GSO 1.5GB		26400 Mtexels/sec
	Difference: 76080 (288%)

Pixel Rate

The GeForce GTX 660 Ti will be quite a bit (more or less 233%) better at FSAA than the GeForce 9600 GSO 1.5GB, and should be capable of handling higher screen resolutions better. (explain)

GeForce GTX 660 Ti		21960 Mpixels/sec
GeForce 9600 GSO 1.5GB		6600 Mpixels/sec
	Difference: 15360 (233%)

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 maximum amount of data (in units of megabytes per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs 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 rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
