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 refreshes Celeron and Pentium desktop lineups
Jun 03, 2012: With the release of Ivy Bridge quad-core processors in April, and announcement of dual-core Ivy Bridge Core i5 and i7 products earlier this week, Intel does not forget about their budget Celeron and Pentium lineups. Because it will be at least several months before both families are transitioned to the new microarchitecture, Intel keeps them up to date by releasing faster versions of Sandy Bridge CPUs. Just today, the company released six new Celeron and Pentium microprocessors, including three SKUs with standard 65 Watt TDP and three low-power "T" SKUs with 35 Watt TDP.

Upcoming budget CPUs surface on Intel website
Apr 23, 2012: Later this quarter Intel will release six Sandy Bridge microprocessors, refreshing their lineup of Celeron and Pentium desktop CPUs. The CPUs are expected to launch on June 3rd. We already reported on their specifications, and last week we published their official prices. S-Spec and box part numbers of some of these SKUs recently surfaced on Intel website in Material Declaration Data Sheets (MDDS) database.

Prices of upcoming Pentium and Celeron desktop CPUs
Apr 19, 2012: Intel budget processor families, currently represented by Pentium and Celeron brands, will be the last to switch to soon to be released Ivy Bridge micro-architecture. Before transitioning budget CPUs to the new microarchitecture, Intel will refresh existing lineup of Pentium and Celeron desktop chips. On June 3rd, together with the second wave of Ivy Bridge products, Intel will release new G540T, G550, G640T, G640, G860T and G870 Sandy Bridge models. We published their specifications in the past, and now we have details on their pricing.

Low-power Intel Pentium G640T and G860T planned for Q2
Apr 02, 2012: Last week we reported on three budget microprocessors spotted in socket 1155 CPU support list on ASRock website. Newly discovered Celeron G540T, G550 and Pentium G640 had slightly higher clock speeds compared to existing Celeron and Pentium models. We recently learned about two other budget Pentium G640T and G860T chips, that will be coming out in the second quarter 2012. One of these processors, G640T, also appeared on ASRock CPU support list.

Intel to refresh Celeron and Pentium lineups
Mar 26, 2012: Last November we reported on several unknown at a time AMD and Intel model numbers, spotted in OEM hardware specifications for Windows 7 Starter and Windows 7 Home Basic operating systems. The document referred to such models as Celeron G550 and G560, Atom N2550, N2750, N2100, N2600, and a few others. Since then Intel launched Atom D2550, and it seems that Atom N2650 and N2850 will be also eventually released. Yesterday we discovered details on yet another processor from that document. Celeron G550 was sighted in socket 1155 CPU support list on ASRock website, along with not yet released Celeron G540 and Pentium G640 CPUs.
