Cores
Cores	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.	Raptor Lake; 8 Performance-cores with Hyper-Threading and 16 Efficient-cores
Clocks
Clocks	Maximum turbo is a single-core frequency; overclocking requires an appropriate motherboard and cooling. Intel publishes TDP without a separate maximum turbo-power figure.	P-core base 3.2 GHz and turbo 5.7 GHz; E-core base 2.4 GHz and turbo 4.5 GHz; Turbo Boost Max 3.0 5.9 GHz; Thermal Velocity Boost up to 6.2 GHz

Memory support
Memory support	Up to 32 GB; two channels; DDR3-1333/1600 or DDR3L-1333/1600 at 1.5 V, as listed by Intel; 25.6 GB/s maximum bandwidth; ECC not supported.	Up to 192 GB; two channels; DDR5-5600 or DDR4-3200; ECC support depends on the motherboard and configuration
PCIe
PCIe	PCIe 3.0; 16 CPU lanes, configured as 1×16, 2×8 or 1×8+2×4.	20 CPU lanes; PCIe 5.0 and 4.0
Chipsets
Chipsets	–	Intel recommends Z790 or Z690 with the latest BIOS
Process
Process	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.	Intel 7
Cooler
Cooler	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.	Maximum operating temperature 100 °C; maker maximum turbo power 253 W. The 320 W Extreme profiles used in launch reviews are separate operating configurations.
