Cores
Cores	8 P-cores and 4 E-cores; 20 threads. Intel Thread Director supported.	Four cores with Hyper-Threading; eight simultaneous threads. PCStats confirms a locked CPU multiplier; base-clock overclocking is possible, so locked does not mean all overclocking is disabled.
Clocks
Clocks	P-cores: 3.6 GHz base, up to 4.9 GHz Turbo Boost 2.0 and 5 GHz Turbo Boost Max 3.0; E-cores: 2.7 GHz base, up to 3.8 GHz turbo.	Intel's product brief gives up to 2.93 GHz single-core Turbo Boost. Intel's 17 November 2008 sale notice names the 920 and confirms immediate system and boxed retail availability.

Memory support
Memory support	Up to 128 GB; two channels; DDR5-4800 or DDR4-3200; 76.8 GB/s; ECC supported with an appropriate platform.	Three channels of DDR3-1066 in Intel's exact-model product brief. A later Intel comparison chart incorrectly lists two channels; the original product brief is used here.
PCIe
PCIe	PCIe 5.0 and 4.0; 20 CPU lanes: 1 × 16 + 4 or 2 × 8 + 4; DMI 4.0 × 8.	Intel's product brief describes X58 chipset PCIe 2.0 graphics connectivity, including two ×16 links. These are chipset connections, not CPU-integrated PCIe lanes. CPU-to-chipset QuickPath Interconnect runs at 4.8 GT/s for the 920.
Process
Process	Intel 7; Alder Lake; 45 × 37.5 mm package; 100°C maximum junction temperature.	45 nm; Nehalem architecture.
Cooler
Cooler	No cooler included with the boxed K processor (Intel support).	Requires an LGA1366/X58 platform; incompatible with LGA775 motherboards. Intel's retired specification page could not be read, so optional package temperature and separate maximum-power values are omitted.
