Cores
Cores	Four P-cores and no E-cores; Hyper-Threading supported.	Four cores and eight threads; Sandy Bridge-E with Hyper-Threading. The multiplier is only partly unlocked, as both exact reviews explain; unlocked is false here because it is not fully unlocked.
Clocks
Clocks	CPU multiplier locked (Intel support). Current Intel specifications list 110 W maximum turbo power; the January 2023 maker launch table and Tom's Hardware list 89 W. ComputerBase also reports 110 W.	Turbo Boost 2.0 up to 3.80 GHz from Intel’s current sheet; KitGuru’s engineering-sample review table instead states 3.90 GHz. Intel staff acknowledged release in February 2012; month precision is retained rather than treating the forum’s proposed day as verified sale.
Cache
Cache	12 MB Intel Smart Cache (L3); 5 MB total L2.	10 MB Intel Smart Cache; L3 level confirmed by both exact reviews.

Memory support
Memory support	Current Intel specifications support up to 192 GB; two channels; DDR5-4800 or DDR4-3200; 76.8 GB/s maximum bandwidth. The January 2023 launch table lists 128 GB.	Four channels of DDR3-1066/1333/1600; 51.2 GB/s maximum published bandwidth; no ECC. Intel’s anomalous 64.23 GB maximum-memory value is not normalised into a guessed capacity.
PCIe
PCIe	PCIe 5.0 and 4.0; 20 CPU lanes, configured as 1×16+4 or 2×8+4; DMI 4.0 ×8.	40 CPU lanes; Intel’s current sheet lists PCIe 2.0, while both contemporary reviews describe PCIe 3.0 capability. The manufacturer’s current literal figure is retained with this conflict explicit.
Chipsets
Chipsets	–	Intel X79; LGA2011.
Process
Process	Intel 7; marketed as Raptor Lake. ComputerBase identifies the H0 Alder Lake die used by the Core i3-12100F. 45 × 37.5 mm package; 100°C maximum junction temperature.	32 nm; Sandy Bridge-E.
Cooler
Cooler	Boxed retail processor includes Intel Laminar RM1 (Intel support).	Exact BX80619I73820 Newegg listing states cooling device not included. Intel gives a case-temperature limit of 66.8°C.
