Haswell 22 nm microarchitecture, released June 3, 2013. Added a number of new instructions, including AVX2 and FMA. Broadwell: 14 nm derivative of the Haswell microarchitecture, released in September 2014. Three-cycle FMUL latency, 64 entry scheduler.
Haswell and Broadwell feature a Fully Integrated Voltage Regulator. Broadwell (previously Rockwell) is the fifth generation of the Intel Core processor. It is Intel's codename for the 14 nanometer die shrink of its Haswell microarchitecture. It is a "tick" in Intel's tick–tock principle as the next step in semiconductor fabrication.
Intel Haswell: 2013 14–19 SoC design, multi-core, multithreading, 2-way simultaneous multithreading, hardware-based transactional memory (in selected models), L4 cache (in GT3 models), Turbo Boost, out-of-order execution, superscalar, up to 8 MB L3 cache (mainstream), up to 20 MB L3 cache (Extreme) Broadwell: 2014 14–19 Multi-core ...
Haswell is the codename for a processor microarchitecture developed by Intel as the "fourth-generation core" successor to the Ivy Bridge (which is a die shrink/tick of the Sandy Bridge microarchitecture). [1]
Haswell Haswell Refresh, Devil‘s Canyon Broadwell Skylake Kaby Lake Coffee Lake Comet Lake Cypress Cove Golden Cove Gracemont: 2008–present 1.1 GHz – 4.4 GHz LGA 1156 LGA 1155 LGA 1366 LGA 2011 LGA 1150 LGA 1151 LGA 1200 LGA 1700: Intel 7, 14 nm, 22 nm, 32 nm, 45 nm 35 W – 130 W 4 - 6 - 8 /w hyperthreading 4.8 GT/s, 8 GT/s 64 ~ 80 KiB ...
The major changes between the Haswell and Skylake architectures include the removal of the fully integrated voltage regulator (FIVR) introduced with Haswell. [54] On the variants that will use a discrete Platform Controller Hub (PCH), Direct Media Interface (DMI) 2.0 is replaced by DMI 3.0, which allows speeds of up to 8 GT/s.
LGA 1150, [1] also known as Socket H3, is a zero insertion force flip-chip land grid array (LGA) CPU socket designed by Intel for CPUs built on the Haswell microarchitecture. This socket is also used by the Haswell's successor, Broadwell microarchitecture. [2] It is the successor of LGA 1155 and was itself succeeded by LGA 1151 in 2015.
Haswell and Haswell Refresh CPUs are supported by all listed chipsets; however, a BIOS update is usually required for 8-Series Lynx Point motherboards to support Haswell Refresh CPUs. [82] Broadwell CPUs are supported only by 9-Series chipsets, which are usually referred to as Wildcat Point. [83]
