Cores
Cores	Hyper-Threading supported; Intel Turbo Boost Max 3.0 targets favoured cores. Thermal Velocity Boost 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	Up to 5.1 GHz with Turbo Boost Max 3.0, or 5 GHz with Turbo Boost 2.0. Configurable TDP-down to 95 W with a 3.5 GHz base clock. Tom's Hardware reports 229 W PL2; the current Intel specification page publishes TDP only.	Maximum turbo is a single-core frequency; overclocking requires an appropriate motherboard and cooling. Intel publishes TDP without a separate maximum turbo-power figure.

PCIe
PCIe	PCIe 3.0; 16 CPU lanes, configured as 1×16, 2×8 or 1×8+2×4.	PCIe 3.0; 16 CPU lanes, configured as 1×16, 2×8 or 1×8+2×4.
Process
Process	14 nm; Comet Lake; 37.5 × 37.5 mm package; 100°C maximum junction temperature. Tom's Hardware identifies the ten-core die with two cores disabled and a soldered thermal interface.	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	No cooler included with the boxed processor (Tom's Hardware exact-model review); an LGA1200-compatible thermal solution is required.	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.
