Intel plans to discontinue 28 desktop microprocessors
Feb 06, 2013: Intel this week announced plans to retire 28 Sandy Bridge desktop CPUs from Celeron, Pentium, Core i3 and Core i5 families. After successful transition of budget desktop microprocessors from Sandy Bridge to Ivy Bridge microarchitecture, it's not surprising to see all phased out parts to be end of lifed.



Intel launches mid-class and budget desktop CPUs
Sep 02, 2012: Shortly after the launch of 22nm Ivy Bridge microarchitecture in April 2012, all Core i5 and i7 desktop products were transitioned to the new technology. Until today, less expensive Pentium and Core i3 processors stayed on older 32nm process. It all changed today, when Intel released Pentium and Core i3 "Ivy Bridge" microprocessors, and refreshed Celeron and Pentium lineups. Overall, the company launched 16 new mid-class and budget SKUs, including one previously unknown model, Core i5-3335S.



Intel Celeron B830 spotted; more details on G645T and G550T CPUs
Aug 01, 2012: Last week we reported that Intel is going to release budget desktop CPUs later in the Q3. New chips, that will use Sandy Bridge core, are Celeron G465, G550T and G555, and Pentium G645 and G645T. While the launch date of upcoming SKUs was known, their specifications were not confirmed. Fortunately, details of two microprocessors, Celeron G550T and Pentium G645T, slipped into Intel's Q3 2012 reference chart. The chart also contains specifications of not yet released mobile Celeron B830 processor.



Intel to refresh Celeron and Pentium lineup in Q3
Jul 25, 2012: Last week we published details of two unreleased Pentium G2100T and G2120 desktop processors. The microprocessors are coming in September 2012, and they will be the first Pentiums, built on Ivy Bridge microarchitecture. What's interesting is that simultaneously with the release of these chips Intel is going to introduce new Sandy Bridge desktop models: G645 and G645T. Also in September, Celeron family will be updated with new G465, G550T and G555 SKUs.
