CoresBroadwell-E; 8 cores with Hyper-Threading. The unlocked multiplier is confirmed by the exact-model reviews.Raptor Lake; 8 Performance-cores with Hyper-Threading and 16 Efficient-cores
ClocksTurbo Boost Max 3.0 up to 4.00 GHz on the preferred core; ordinary Turbo Boost 2.0 up to 3.70 GHz. The main boost field uses Intel’s highest published frequency. May availability follows Tom’s Hardware’s 31 May 2016 report, attributing immediate sale of all four models to Intel. Intel’s family record is dated 30 May and ARK gives Q2 2016; the announcement day is not treated as an exact first-sale day.P-core base 3.2 GHz and turbo 5.4 GHz; E-core base 2.4 GHz and turbo 4.3 GHz; Turbo Boost Max 3.0 5.8 GHz; Thermal Velocity Boost up to 6 GHz

ChipsetsX99 and LGA2011-v3, distinguished by Intel’s exact-model comparison chart and the reviews. Current ARK abbreviates the socket as FCLGA2011; this is not compatible with the older X79 LGA2011 platform.Intel recommends Z790 or Z690 with the latest BIOS
Process14 nm; Broadwell-E.Intel 7
CoolerIntel explicitly excludes a fan and heatsink from the boxed product; a separate compatible cooler is required.Maximum operating temperature 100 °C; maker maximum turbo power 253 W. The 320 W Extreme profiles used in launch reviews are separate operating configurations.
