GeForce 9600 GSO 1.5GB vs GeForce GT 220 GDDR3

Intro

Compare all that to the GeForce GT 220 GDDR3, which makes use of a 40 nm design. nVidia has set the core frequency at 625 MHz. The GDDR3 memory works at a frequency of 1012 MHz on this specific model. It features 48 SPUs along with 16 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 220 GDDR3		58 Watts
GeForce 9600 GSO 1.5GB		84 Watts
	Difference: 26 Watts (45%)

Memory Bandwidth

Theoretically, the GeForce 9600 GSO 1.5GB should perform a little bit faster than the GeForce GT 220 GDDR3 in general. (explain)

GeForce 9600 GSO 1.5GB		38400 MB/sec
GeForce GT 220 GDDR3		32384 MB/sec
	Difference: 6016 (19%)

Texel Rate

The GeForce 9600 GSO 1.5GB should be a lot (more or less 164%) faster with regards to anisotropic filtering than the GeForce GT 220 GDDR3. (explain)

GeForce 9600 GSO 1.5GB		26400 Mtexels/sec
GeForce GT 220 GDDR3		10000 Mtexels/sec
	Difference: 16400 (164%)

Pixel Rate

The GeForce 9600 GSO 1.5GB should be much (more or less 32%) more effective at AA than the GeForce GT 220 GDDR3, and also should be able to handle higher screen resolutions while still performing well. (explain)

GeForce 9600 GSO 1.5GB		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 (in units of megabytes per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the 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 amount of pixels that the graphics card could possibly record to its 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 called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
