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.


CPU ID information for the Core 2 Quad Q8400

Detailed characteristics of processor's internals, including x86 instruction set extensions and individual instructions, high- and low-level technologies, are listed below. This list was acquired from an actual Intel Core 2 Quad Q8400 processor with the help of the x86 CPUID instruction. Any discrepancies between CPUID features and official specifications are likely due to some features being disabled in BIOS, or due to a bug in our CPUID decoding algorithm. Different steppings of Intel processors may also have slightly different features.
