Intel launches Haswell desktop processors
Sep 01, 2013: Intel today introduced new Core i3 and Pentium microprocessors, built on three-month old Haswell architecture. The company also refreshed Core i5, Core i7 and Celeron lines with new Haswell and Ivy Bridge models, and released Xeon E3-1220L v3 model, that was announced in June 2013. Brief specifications, as well as prices of these products are available in the official price list, that was updated last night.

Upcoming Core i3 and Pentium Haswell CPUs are available for pre-order
Aug 19, 2013: At Computex show earlier this year Intel launched first desktop microprocessors, built on Haswell microarchitecture. The initial wave of desktop chips was comprised mostly of quad-core products, priced between $180 and $400. The next wave of Haswell processors is coming in September. It is expected that Intel will release full range of Pentium and Core i3 SKUs, that will replace currently available Ivy Bridge-based Pentium and Core i3 models.

Intel desktop and mobile roadmaps leaked
Jul 26, 2013: Yesterday VR-Zone leaked several slides from Intel desktop and mobile roadmaps. The slides do not have much of new information, with the exception of a launch date of Broadwell mobile processors. Last month, we reported that Broadwell mobile CPUs will be available in the first half of 2014. Apparently, the launch was postponed until the second half of the year.

New Intel desktop CPUs to launch in September
Jun 25, 2013: A number of new Haswell desktop processors recently emerged in a leaked Intel roadmap, including Core i7-4771, Core i5-4440, i5-4440S, along with Core i3 and Pentium CPUs. A specifications slide, leaked separately from the roadmap, revealed a few additional low power Haswell SKUs from Core i3 and Pentium families. According to a screenshot, posted by VR-Zone last Sunday, all aforementioned microprocessors will be launched in September.

Details of Haswell Pentium and Core i3 CPUs surfaced
Jun 16, 2013: Earlier this week we published a story about new Intel desktop roadmap, spotted on website. After the story was posted, the site added another picture with specifications of all future Haswell-based Core i3 and Pentium microprocessors for socket 1150, including several "T" low-power models, that were not referenced in the original slides. The specs slide also contains details of unreleased Core i5-4440, i5-4440S, i7-4820K, i7-4930K, and i7-4960X SKUs.

Intel desktop roadmap for H2 2013 and H1 2014
Jun 13, 2013: Haswell desktop processors debuted last week, and, as was the case with Sandy Bridge and Ivy Bridge launches, the initial lineup consisted of Core i5 and i7 quad-core models. Less expensive products, such as Core i3 and Pentium CPUs, were expected later this year, but we didn't have much information about specific SKUs up until now. We recently stumbled on a few slides from Intel desktop roadmap, that shed more light on Haswell mid-range lineup.

Are you sure about the support for AES & AVX2 instruction sets?

Looks like Intel felt the pinch from Richland APUs..coz previously i3 had no AES only AVX..

APUs carry 4MB cache too..albeit L2.

What about hardware virtualization? support for that too? coz even lowest end AMD APUs support it.

Response: AES and VT-x will be supported. There is not support for I/O virtualization (VT-d). I'm not sure about AVX2, so I updated the pages to indicate that.
