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; Devil's Canyon, a Haswell refresh; 37.5 × 37.5 mm package; 74.04°C Tcase limit, not a junction-temperature limit. New polymer thermal interface and additional capacitors, described in Intel's Computex launch coverage and the exact-model reviews.
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.	Intel lists both ordinary boxed and explicitly fanless boxed SKUs; cooler contents should be checked for the particular package. Compatible Intel 8- and 9-series chipsets require the appropriate motherboard BIOS. Intel's June 2014 fact sheet confirms volume availability that month; the announcement itself is not used as the on-sale day.
