Intel discontinues Pentium and Core-branded desktop CPUs

Dec 08, 2011: In the wake of the launch of desktop Ivy Bridge microprocessors, coming in the second quarter 2012, Intel prepares to discontinue large number of desktop models due to low demand. In the past two days, the company published several Product Change Notification (PCN) documents, that notify customers of upcoming discontinuation of 19 socket 1366, socket 1156, and socket 1155 chips. Full list of retired SKUs includes.

Intel launches Sandy Bridge Pentium and Core CPUs

May 22, 2011: Today Intel updated official pricelist with information on 7 new microprocessors, all built on the latest Sandy Bridge microarchitecture. Prices of existing processors were left unchanged. The list of new models includes mainstream Pentium G620, G840 and G850, low-power Pentium G620T, Core i3-2105 and i5-2405S with beefed-up graphics, and incrementally faster Core i5-2310.

Intel desktop Sandy Bridge CPUs to launch on May 22

May 09, 2011: Less than two weeks remains before introduction of the next wave of Sandy Bridge microprocessors for desktop market. The processor lineup, that will be released on Sunday, May 22, consists of 7 new Pentium, Core i3 and Core i5 SKUs. Pentium models will be the first budget CPUs, built on Sandy Bridge micro-architecture. Core i3s and i5s, on the other hand, are updated versions of previously released chips with slightly better CPU or graphics performance.
