Process
Process	22 nm; Ivy Bridge; 3D tri-gate transistors; 37.5 × 37.5 mm package; 67.4°C Tcase limit, not a junction-temperature limit.	22 nm
Cooler
Cooler	LGA1155-compatible cooling required. Intel announced the quad-core family on 23 April 2012; Ars Technica's contemporaneous launch report quotes Newegg confirming retail sale on 29 April. The archived maker sale notice could not be read, so the day is supported by named secondary retail coverage.	–
