The Core i3-3220 and the i3-3220T belong to Intel’s Ivy group of processors. The key difference between these is their TDP rating ( If you are un initiated, you may like to read about TDP rating here ). The i3-3220T is a low TDP part at 35 Watts rating while the i3-3220 is a rated at 55 Watts.
To achieve the low TDP, the core voltage has to to kept lower, since, the law of Physics tells that the power consumed is directly proportional to the square of voltage. And as you lower the voltage, the frequency it can reach is reduced. So you get a lower power part that works at 2.80 GHz in place of 3.30 GHz. You obviously sacrifice the maximum performance for lower power.
Other specifications stay same.

Some more details of Core i3-3220
Core i3-3220 is the 3rd generation Core i3 processor belonging to its Ivy Bridge series. Compared to the 2nd generation Core i3 ( Sandy Bridge), it comes with 10% clock to clock improvement and a a better graphics – HD Graphics 2500. The quick sync is also improved substantially , that helps speedier encoding and decoding of video.
