Intel wants to push out Ivy Bridge rollouts throughout the year, and not just dump everything onto the table at once. This means that we won't see Core i3 Ivy Bridge-based processors until Q3, even after most people had hoped to have seen them introduced in June.
When Intel does launch the Core i3 desktop models, we should expect to see a top-to-bottom release of: 3.4GHz Core i3-3240, the 3GHz Core i3-3240T, the 3.3GHz Core i3-3225, the 3.3GHz Core i3-3220 and the 2.8GHz Core i3-3220T. All five models sport 3MB of shared L3 cache, two cores and hyper threading.
The standard models are rated at 55W TDP, with the T models destined for all-in-one systems, and are rated at 35W TDP. The exception here is the Core i3-3225 which features Intel HD graphics 4000, with the four other models being filled with Intel HD graphics 2500. Intel is set to add support for AES to the new Core i3 models. No pricing has been mentioned, but it should fall close to the price of the Sandy Bridge-based CPUs out now.
