Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT DDR2		50 Watts
GeForce GT 220 GDDR3		58 Watts
	Difference: 8 Watts (16%)

Memory Bandwidth

In theory, the GeForce GT 220 GDDR3 should be 102% quicker than the GeForce 9500 GT DDR2 overall, due to its greater bandwidth. (explain)

GeForce GT 220 GDDR3		32384 MB/sec
GeForce 9500 GT DDR2		16000 MB/sec
	Difference: 16384 (102%)

Texel Rate

The GeForce GT 220 GDDR3 is a little bit (approximately 14%) better at anisotropic filtering than the GeForce 9500 GT DDR2. (explain)

GeForce GT 220 GDDR3		10000 Mtexels/sec
GeForce 9500 GT DDR2		8800 Mtexels/sec
	Difference: 1200 (14%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GT 220 GDDR3 is superior to the GeForce 9500 GT DDR2, but it probably won't make a huge difference. (explain)

GeForce GT 220 GDDR3		5000 Mpixels/sec
GeForce 9500 GT DDR2		4400 Mpixels/sec
	Difference: 600 (14%)

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 max amount of information (counted in MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
