Intel discontinues Pentium, Core 2 Duo and Core 2 Quad CPUs
Feb 08, 2011: Last October, we published a story detailing upcoming discontinuation of many Core 2 Duo and Core 2 Quad microprocessors, and two Pentium Dual-core models. Yesterday Intel published Product Discontinuation Notifications (PDN), that provide End-of-Life milestone dates for these CPUs.



Intel to discontinue Core 2 Quad CPUs in 2011
Oct 05, 2010: In August, Jetway Computer Corporation updated Q3 desktop motherboard roadmap, and added discontinuance notice for Intel socket 775 microprocessors. As stated by the roadmap document, Product Discontinuance Notices (PDN) were published for Core i7-975 and Celeron E3200 CPUs in Q3 2010, and the last order date for these CPUs is Q1 2011. In the first quarter 2011 Intel plans to issue PDNs for Core 2 Quad Q8300, Q8400, Q8400S, Q9505, Q9505S, Q9550, Q9550S and Q9650 CPUs. Discontinuance notices will also be posted for Core 2 Duo E8500 and E8600 models, and Pentium Dual-Core E5400 processor.
