Cores
Cores	6 P-cores and no E-cores; 12 threads. Intel Thread Director is not supported.	Four cores with Hyper-Threading; Intel Turbo Boost 2.0 supported. The current maker page lists Transactional Synchronization Extensions as unsupported, superseding early review specifications.
Clocks
Clocks	2.5 GHz P-core base, up to 4.4 GHz P-core turbo; locked multiplier confirmed by io-tech and TechPowerUp.	Maximum turbo is a single-core frequency; overclocking requires an appropriate motherboard and cooling. Intel publishes TDP without a separate maximum turbo-power figure.
Cache
Cache	18 MB Intel Smart Cache (L3); 7.5 MB total L2.	–

Process
Process	Intel 7; Alder Lake; FCLGA1700, 45 × 37.5 mm package; 100°C Tjunction.	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	Intel Laminar RM1 included with boxed retail processor (Intel support).	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.
