Cores
Cores	Wolfdale; two cores and two threads, without Hyper-Threading. Intel’s archived exact E8400 specifications are attached to the maker datasheet distributed by Mouser.	Four P-cores and no E-cores; Hyper-Threading supported.
Clocks
Clocks	Published operating frequency 3.00 GHz; 1333 MHz front-side bus. Intel explicitly lists no Turbo Boost, so no boost figure is supplied. Intel’s CES fact sheet specifies January 2008 availability for this exact model; TechSpot’s 1 February review confirms retail stock, with early shortages and prices above target. An exact first-sale day remains unverified.	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.
Cache
Cache	6 MB shared L2 cache; no L3 figure supplied.	12 MB Intel Smart Cache (L3); 5 MB total L2.
