Overview
Released
Released	January 2024	February 2012
Cores and clocks
Cores
Cores	14 (6 performance, 8 efficiency) (better)	4
Threads
Threads	20 (better)	8
Base clock
Base clock	2.6 GHz	3.6 GHz
Boost clock
Boost clock	5 GHz (better)	3.8 GHz
L3 cache
L3 cache	24 MB (better)	10 MB
Cores
Cores	6 P-cores and 8 E-cores; 20 threads. ComputerBase identifies its tested sample as C0 Alder Lake silicon within the marketed Raptor Lake Refresh generation.	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	P-cores: 2.6 GHz base, up to 5.0 GHz turbo. E-cores: 1.9 GHz base, up to 3.7 GHz turbo.	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	24 MB Intel Smart Cache (L3); 11.5 MB total L2.	10 MB Intel Smart Cache; L3 level confirmed by both exact reviews.

Memory support
Memory support	Up to 192 GB; two channels; DDR5-4800 or DDR4-3200; 76.8 GB/s; ECC supported with an appropriate platform.	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: 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 600- and 700-series motherboards; appropriate BIOS support required.	Intel X79; LGA2011.
Process
Process	Intel 7; Raptor Lake Refresh generation. ComputerBase identifies the tested sample as C0 Alder Lake silicon. 45 × 37.5 mm package; 100°C maximum junction temperature.	32 nm; Sandy Bridge-E.
Cooler
Cooler	Intel Laminar RM1 included with the boxed processor (Intel support).	Exact BX80619I73820 Newegg listing states cooling device not included. Intel gives a case-temperature limit of 66.8°C.
