GeForce GT 220 GDDR3		32384 MB/sec
	Difference: 159872 (494%)

Texel Rate

The Geforce GTX 760 should be much (about 841%) more effective at texture filtering than the GeForce GT 220 GDDR3. (explain)

Geforce GTX 760		94080 Mtexels/sec
GeForce GT 220 GDDR3		10000 Mtexels/sec
	Difference: 84080 (841%)

Pixel Rate

The Geforce GTX 760 should be quite a bit (about 527%) faster with regards to FSAA than the GeForce GT 220 GDDR3, and should be capable of handling higher screen resolutions without losing too much performance. (explain)

Geforce GTX 760		31360 Mpixels/sec
GeForce GT 220 GDDR3		5000 Mpixels/sec
	Difference: 26360 (527%)

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 max amount of data (in units of MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the video 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 maximum number of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel 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 max fill rate.
