Intel Haswell and Broadwell Microprocessor Variants Detailed – Broadwell Compatible with Socket LGA1150


The microprocessors variants for Intel Haswell and Broadwell generation core series have been leaked. According to PCWatch, the '2M' microprocessor node features four cores and 8 MB of L3 Cache while the '1M' node feature dual-cores with 4 MB of L3 Cache. Intel Haswell and Broadwell which would be the companies first true SOC desig (System on Chip) would be available in - LGA (Desktop), BGA (Mobile) and PGA (Mobile) packages.

4th Generation Intel Haswell SOC:

Intel Haswell which is based on the 22nm 3D Tri-gate architecture arrives in April-May 2013. The Haswell series is made up of the following variants:

  • Haswell-DT (Desktop)
  • Haswell-H  (Mobile)
  • Haswell-MB (Mobile)
  • Haswell-ULT (Ultra Low TDP)
  • Haswell-ULX (Ultra Extremely Low TDP)

The Haswell-DT lineup which would be compatible with LGA 1150 socket motherboards has already been detailed by us here. In addition to desktop, there would be two mobile variants, Haswell-H for laptops and Haswell-MB for tablets and netbooks while Haswell-ULT would focus on Ultra low TDP notebooks and Haswell-ULX would further cut down the TDP for lower power Ultrabooks.

Haswell-DT (Desktop) would feature both Quad Core and Dual-Core models with TDPs ranging between 84/65/45/35 Watts for the Quad Core and 54/35 Watts for the Dual core models.Mobile chips would be shipped in BGA and PGA '2M' packages with the inclusion of GT2 graphics. The Haswell-ULT and Haswell-ULX with 15/13.5 and 10 Watt TDP would be complete SOCs with GT3 graphics onboard the die making them exceptionally well for the Ultrabook and Tablet market.

5th Generation Intel Broadwell SOC:

Intel Broadwell would be the companies first 14nm core series also being a much mature SOC design. The naming scheme of the Broadwell 5th generation processors gets much simple as you can note from the list below:

  • Broadwell-D (Desktop)
  • Broadwell-H (Mobile)
  • Broadwell-M (Mobile)
  • Broadwell-U (Ultra Low TDP)
  • Broadwell-Y (Ultra Low Power)

One conformation we get from this is that Intel is definitely not looking to skip the entire desktop lineup in order to ship them in BGA packages as reported earlier. Broadwell desktop processors would exisit but only the '2M' grade series which include Quad Core models with 8 MB L3 Cache, Dual Core models would not be shipped with the Broadwell generation of CPUs in LGA package but rather PGA packages.

Broadwell-H would be shipped in BGA package while Broadwell-M in PGA and would have TDPs rated at 55-35W. The low power CPU department for Broadwell generation would get Haswell-U and Haswell-Y which would have TDP set around 10-15W. The iGP chipset has not been mentioned but its known that the Broadwell GPU would push performance by 40 percent over Haswell.

In addition to this, Ivy Bridge-E is expected to launch in Mid-2013 as Intel's second LGA 2011 HEDT (High-End Desktop) platform. Intel Haswell launches in April-May 2013 followed by Intel Broadwell a year later.
