Details of desktop Core i7 and Core i5 "Ivy Bridge" processors in the LGA1155 package have been detailed at lengths, in the past. Core i3 parts based on the same 22 nm Ivy Bridge silicon, however, were relatively known. Tables listing out updated information about the lineup points out that Intel has as many as five Core i3 "Ivy Bridge" desktop processors in the works, all dual-core, and among which two are low-power parts.
The table also suggests that these Core i3 chips will have reduced features, importantly, the lack of PCI-Express 3.0 bus. When connected to these chips, PCI-E 3.0 add-on cards (such as graphics cards) will function in PCI-Express 2.0 mode. Further, these chips will lack support for AES-NI (accelerates encryption), VT-d (enhanced virtualization), and TXT (security). Certain models in the lineup have faster integrated graphics, denoted by a "5" in the end of the model number. These chips also lack Turbo Boost for the x86 cores, but feature HyperThreading.
