GeForce 9600 GSO 384MB vs GeForce GT 220 GDDR3

Intro

Compare those specs to the GeForce GT 220 GDDR3, which has a GPU core clock speed of 625 MHz, and 512 MB of GDDR3 memory set to run at 1012 MHz through a 128-bit bus. It also is made up of 48 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.

Pixel Rate

The GeForce 9600 GSO 384MB will be a lot (about 32%) more effective at anti-aliasing than the GeForce GT 220 GDDR3, and also able to handle higher screen resolutions without losing too much performance. (explain)

GeForce 9600 GSO 384MB		6600 Mpixels/sec
GeForce GT 220 GDDR3		5000 Mpixels/sec
	Difference: 1600 (32%)

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 information (measured in megabytes per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
