Edit Subarch: Intel64-haswell

{{DockerBlurb}} {{Warning|Haswell "Pentium" processors are missing AVX and AES instructions, so they are not included in the CPU list below. Use [[intel64-nehalem]] instead.}} 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 E3 v3 and E5 v3 Familes. 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 AVX instructions. 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].
