Overview
Released
Released	January 2007	June 2013
Cores and clocks

Base clock
Base clock	2.4 GHz	3.5 GHz
Boost clock
Boost clock	–	3.9 GHz
L3 cache
L3 cache	–	8 MB
Cores
Cores	Kentsfield; four cores and four threads, without Hyper-Threading. Original B3 stepping is the numerical baseline; later G0 retains the model name and core/cache figures. Locked multiplier confirmed by bit-tech’s exact-model review.	Four cores with Hyper-Threading; Intel Turbo Boost 2.0 supported. The unlocked multiplier is confirmed by Expert Reviews and TechRadar. Current Intel specifications list TSX and VT-d as unsupported.
Clocks
Clocks	Published operating frequency 2.40 GHz; 1066 MHz front-side bus. Intel’s 8 January 2007 release explicitly states immediate availability in PCs and the reseller channel. No unpublished boost frequency is supplied.	Maximum turbo is a single-core frequency; sustained clocks depend on cooling and motherboard settings. Intel's June 2013 availability notice and Puget Systems' June launch lineup establish the sale month; they do not establish a worldwide first-sale day.
Cache
Cache	Two 4 MB L2 caches, one per dual-core die; total 8 MB. Intel’s datasheet also lists four 32 KB L1 data caches. No L3 figure is supplied.	–

Graphics
Graphics	No integrated graphics, confirmed by the exact BX80562Q6600 retail listing; motherboard graphics are a separate component.	Intel HD Graphics 4600; 350 MHz base, up to 1.25 GHz; three displays; Quick Sync Video.

Memory support
Memory support	Memory and I/O transactions pass through the front-side bus and chipset, as Intel’s datasheet states; memory types and capacity depend on the motherboard.	Up to 32 GB; two channels; DDR3-1333/1600 and DDR3L-1333/1600 at 1.5 V; 25.6 GB/s maximum bandwidth; ECC not supported.
PCIe
PCIe	–	PCIe 3.0; 16 CPU lanes, configured as 1×16, 2×8 or 1×8+2×4.
Process
Process	65 nm; Kentsfield; LGA775.	22 nm; Haswell; 37.5 × 37.5 mm package; 72.72°C maximum case temperature, not junction temperature.
Cooler
Cooler	Boxed BX80562Q6600 listing confirms heatsink and fan. Intel’s datasheet and PCN107463 distinguish original B3 105 W from later G0 95 W; the projected July 2007 conversion date is not treated as an independently verified sale day.	Requires an LGA1150 motherboard; earlier LGA1155 processors use a different socket. No separate maximum turbo-power figure is published in the current Intel specifications.
