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.



Bits and pieces: unreleased Intel CPUs spotted
Aug 16, 2012: In the 4th quarter 2012, Intel's Extreme segment of desktop market will be updated with Core i7-3970X. Details of this CPU were revealed by DonanimHaber, and later confirmed by a roadmap, leaked by VR-Zone. Existence of this SKU was also confirmed earlier this month by Intel, when the Core i7-3970X was added to Intel's Material Declaration Data Sheets (MDDS) database.



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.



Intel Pentium G645 spotted
Jun 24, 2012: Two weeks ago we reported on new Celeron G465 and G555 dual-core microprocessors, that surfaced in Intel's Material Declaration Data Sheets (MDDS) database. Presumably, the Celerons with Gxx5 processor numbers will have CPU features, similar to G460 and G550 products, while offering slightly higher graphics performance. Yesterday Intel published details of yet another Gxx5 processor, this time it's a Pentium G645.

Intel G645 Benchmarks

The graphs below show up to 10 microprocessors with approximately the same level of integer (CPU), floating-point (FPU), SIMD and memory performance. All processors were not overclocked, and were tested at a nominal frequency, with a stock heatsink and default BIOS settings. Click on the '?' mark next to each model name to see specifications of that model, and details of the test platform. To find out how the G645 compares to other CPUs in specific benchmarks or in aggregate milti-threading performance please see benchmark tools section on the right.
