Yesterday Intel published several Product Change Notification (PCN) documents, advising their customers about upcoming discontinuation of Core i5 and i7 processors, and one Celeron SKU. Most of retired microprocessors are based on older Sandy Bridge microarchitecture, and they were introduced in the January - October 2011 time frame. These CPUs are Celeron G440, Core i5-2310, i5-2320, i5-2400, i5-2400S, i5-2405S, i5-2500, i5-2500K, i5-2500S, i5-2500T, Core i7-2600, i7-2600K, i7-2600S and i7-2700K. Additionally, Intel will discontinue one Ivy Bridge part, Core i5-3450. The EOL date, or the last order date, for all aforementioned SKUs is March 29, 2013. Boxed parts will be shipped while supplies last. The last shipment date of tray/OEM parts is September 27, 2013. Core i5-2400 and i7-2600 will still be offered as embedded products after the EOL date.
The latest discontinuation notices cover most of the second-generation Core i5 and i7 lineups. Taking into account that Intel previously published PCNs for GPU-less Core i5s and i5-2300, it's evident that all i5 and i7 Sandy Bridge products will be end-of-lifed before April 2013, that is before the launch of fourth-generation Haswell microprocessors.
