The '''intel64-haswell''' subarch specifically supports processors based on Intel's [[Wikipedia:Haswell_(microarchitecture)|Haswell microarchitecture]]. Haswell desktop processors are branded as 4th Generation Intel Core i3, Core i5, and Core i7 Processors. Many of the released processors are APUs, containing integrated Intel graphics support. Haswell Xeon processors include the Xeon E5 v3 Family.
Beginning in November 2008, Intel launched the first Core i7 processor, codenamed [[Wikipedia:Bloomfield_(microprocessor)|Bloomfield]], based on the [[Wikipedia:Nehalem_(microarchitecture)|Nehalem]] microarchitecture. With this launch, they also added to and modified the conventions used in their [[Wikipedia:Intel_Core|Intel Core]] branding scheme. '''(Not to be confused with the [[Wikipedia:Intel Core (microarchitecture)|Intel Core microarchitecture]]. See [[core2_64]].)'''. This new naming scheme distinguishes between grades of processors rather than microarchitectures or design. Therefore, the '''corei7''' subarch supports the [[Wikipedia:Nehalem_(microarchitecture)|Nehalem]], [[Wikipedia:Westmere_(microarchitecture)|Westmere]], [[Wikipedia:Sandy_Bridge_(microarchitecture)|Sandy Bridge]], [[Wikipedia:Ivy_Bridge_(microarchitecture)|Ivy Bridge]], and [[Wikipedia:Haswell_(microarchitecture)|Haswell]] microarchitectures under the following brand names:


One of the new instruction sets with this subarch is '''AVX2''' (Advanced Vector Extensions 2), also known as ''Haswell New Instructions'', introduced June of 2013, as an expansion of the AVX instruction.
* Intel Pentium/Celeron (low-level consumer)
* Intel Core i3 (entry-level consumer)
* Intel Core i5 (mainstream consumer)
* Intel Core i7 (high-end consumer/business)
* Intel Xeon (business server/workstation)


Intel AVX instructions require operating system support and have been in the Linux kernel since 2.6.30. Additionally, they require slightly more power to execute. When executing these instructions, the processor may run at less than the marked frequency to maintain thermal design power (TDP) limits. For more information about these instructions, see [http://www.intel.com/content/dam/www/public/us/en/documents/white-papers/performance-xeon-e5-v3-advanced-vector-extensions-paper.pdf this link].

Revision as of 09:36, December 20, 2014

This section lists the CPU-optimized Funtoo Linux builds currently available for download for corei7. The corei7 subarch supports the Nehalem, Westmere, Sandy_Bridge, Ivy Bridge, and Haswel microarchitecture-based Intel Pentium/Celeron, Intel Core i3, i5, i7 and Xeon Processors.

No downloadable stage builds are currently available for this sub-architecture.

The corei7 subarch supports the Nehalem, Westmere, Sandy_Bridge, Ivy Bridge, and Haswel microarchitecture-based Intel Pentium/Celeron, Intel Core i3, i5, i7 and Xeon Processors..

Architecture and Optimization

The following settings are applied to all stages for this subarch via Funtoo subarch profiles:

CHOSTx86_64-pc-linux-gnu
CFLAGS-march=corei7 -O2 -pipe


Beginning in November 2008, Intel launched the first Core i7 processor, codenamed Bloomfield, based on the Nehalem microarchitecture. With this launch, they also added to and modified the conventions used in their Intel Core branding scheme. (Not to be confused with the Intel Core microarchitecture. See core2_64.). This new naming scheme distinguishes between grades of processors rather than microarchitectures or design. Therefore, the corei7 subarch supports the Nehalem, Westmere, Sandy Bridge, Ivy Bridge, and Haswell microarchitectures under the following brand names:

  • Intel Pentium/Celeron (low-level consumer)
  • Intel Core i3 (entry-level consumer)
  • Intel Core i5 (mainstream consumer)
  • Intel Core i7 (high-end consumer/business)
  • Intel Xeon (business server/workstation)

See the following links for a list of supported Celeron, Pentium, Nehalem, Westmere, Sandy Bridge, Ivy Bridge, and Haswell processors.
