What reviewers say
Both reviews found better application performance than equally clocked Conroe processors. Bit-tech praised the E8400’s value, gaming performance and lower system power, while favouring quad cores for heavily threaded work. TechSpot saw little gaming benefit in its GPU-limited tests and advised existing Core 2 Duo owners against upgrading just for Wolfdale.
Wolfdale; two cores and two threads, without Hyper-Threading. Intel’s archived exact E8400 specifications are attached to the maker datasheet distributed by Mouser.
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.
Cache
6 MB shared L2 cache; no L3 figure supplied.
Graphics and AI
Built-in graphics
No
Graphics
No integrated graphics, explicitly confirmed by the exact BX80570E8400 Newegg listing; motherboard graphics are separate.
Platform
Socket
LGA775
Base power
65 W
Cooler in the box
Yes
Memory support
Memory and I/O transactions pass through the front-side bus and chipset, as Intel’s datasheet states; supported memory types and capacity depend on the motherboard.
Process
45 nm; Wolfdale; LGA775; SSE4.1 support.
Cooler
Intel’s boxed-processor specification confirms a supplied cooling solution; exact BX80570E8400 listing confirms heatsink and fan. Published processor TDP is 65 W.
Pros and cons
Pros
+6 MB shared L2 cache
+45 nm manufacturing process
