GeForce GT 220 GDDR3		32384 MB/sec
	Difference: 150016 (463%)

Texel Rate

The Radeon R9 380X is a lot (more or less 1142%) more effective at anisotropic filtering than the GeForce GT 220 GDDR3. (explain)

Radeon R9 380X		124160 Mtexels/sec
GeForce GT 220 GDDR3		10000 Mtexels/sec
	Difference: 114160 (1142%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R9 380X is the winner, by a large margin. (explain)

Radeon R9 380X		31040 Mpixels/sec
GeForce GT 220 GDDR3		5000 Mpixels/sec
	Difference: 26040 (521%)

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 data (counted in megabytes per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 can be processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core 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 output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
