64-bit computing - Wikipedia

    https://en.wikipedia.org/wiki/64-bit_computing
    However, not all 64-bit instruction sets support full 64-bit virtual memory addresses; x86-64 and ARMv8, for example, support only 48 bits of virtual address, with the remaining 16 bits of the virtual address required to be all 0's or all 1's, and several 64-bit instruction sets support fewer than 64 bits of physical memory address.

x86-64 - Wikipedia

    https://en.wikipedia.org/wiki/X86-64
    x86-64 (also known as x64, x86_64, AMD64 and Intel 64) is the 64-bit version of the x86 instruction set.It introduces two new modes of operation, 64-bit mode and compatibility mode, along with a new 4-level paging mode. With 64-bit mode and the new paging mode, it supports vastly larger amounts of virtual memory and physical memory than is possible on its 32-bit …

A64 Instruction Set – Arm Developer

    The A64 instruction set introduces a number of changes from the A32 and T32 instruction sets. These changes include: New instructions to support 64-bit operands. Most instructions support 32-bit or 64-bit arguments. Assumes 64-bit address size. All addresses are assumed to be 64-bits in size. LP64 and LLP64 are the primary data models targeted.

x86-64 Instructions Set

    x86-64 Instructions Set CPU instructions. The general-purpose instructions perform basic data movement, arithmetic, logic, program flow, and string operations which programmers commonly use to write application and system software to run on Intel 64 and IA-32 processors.

    So, a 64 bit sysrescuecd kernel does run on this box, and its /proc/cpuinfo tells me that it does indeed have a core i5-6200U cpu which, per Google, does support the x86-64 instruction set.

    Sep 28, 2008 · Furthermore, my understanding is that the x86 (32-bit) processors used in PCs and Apple Macs are not able to completely emulate the x64 (64-bit) instruction set. Some 64-bit instructions cannot be trapped by the emulator. This causes the system to crash when the x86 processor tried to run those x64 instructions.4.5/5(641)

simd - Do all 64 bit intel architectures support SSSE3 ...

    https://stackoverflow.com/questions/28185844/do-all-64-bit-intel-architectures-support-ssse3-sse4-1-sse4-2-instructions
    A CPU with x64 native support but no SSE3 support is going to be 'first-generation' 64-bit which isn't supported by Windows 8.1 x64 native due to the requirements for CMPXCHG16b, PrefetchW, and LAHF/SAHF; so in practice SSE3 is highly likely in newer machines. SSSE3 or later is more restrictive depending on exactly who you are aiming at.
