Most applications bundled with Mac OS X 10.6 are now also 64-bit. [24] 2011 Apple releases Mac OS X 10.7, "Lion", which runs the 64-bit kernel by default on supported machines. Older machines that are unable to run the 64-bit kernel run the 32-bit kernel, but, as with earlier releases, can still run 64-bit applications; Lion does not support ...
Alpha (original name Alpha AXP) is a 64-bit reduced instruction set computer (RISC) instruction set architecture (ISA) developed by Digital Equipment Corporation (DEC). Alpha was designed to replace 32-bit VAX complex instruction set computers (CISC) and to be a highly competitive RISC processor for Unix workstations and similar markets.
Mac OS X 10.4.7 and higher versions of Mac OS X 10.4 run 64-bit command-line tools using the POSIX and math libraries on 64-bit Intel-based machines, just as all versions of Mac OS X 10.4 and 10.5 run them on 64-bit PowerPC machines. No other libraries or frameworks work with 64-bit applications in Mac OS X 10.4. [99]
Microsoft Windows, for example, designates its 32-bit versions as "x86" and 64-bit versions as "x64", while installation files of 64-bit Windows versions are required to be placed into a directory called "AMD64". [20] In 2023, Intel proposed a major change to the architecture referred to as X86S (formerly known as X86-S). The S in X86S stood ...
Support for 32-bit Windows was removed in 6.0. Support for Windows 2000 was removed in version 1.6. [76] [77] Support for Windows XP was removed in version 5.0. [78] [79] Support for Windows Vista was removed in version 5.2. Support for Windows 7 (64-bit) was removed in version 6.1. Support for Windows 8 (64-bit) was removed in version 7.0. [80 ...
Itanium (/ aɪ ˈ t eɪ n i ə m /; eye-TAY-nee-əm) is a discontinued family of 64-bit Intel microprocessors that implement the Intel Itanium architecture (formerly called IA-64). The Itanium architecture originated at Hewlett-Packard (HP), and was later jointly developed by HP and Intel.
Yellow Dog Linux, full support for 32/64-bit; PS3; Void Linux, support in third-party fork [27] for 32-bit and 64-bit (big-endian and little-endian) Solaris 2.5.1 PowerPC edition on the PReP platform OpenSolaris, experimental [28] [29] JavaOS; Windows NT 3.5, [30] 3.51 and 4.0; ReactOS, PowerPC port no longer under active development [31]
The first Pentium 4-branded processor to implement 64-bit was the Prescott (90 nm) (February 2004), but this feature was not enabled. Intel subsequently began selling 64-bit Pentium 4s using the "E0" revision of the Prescotts, being sold on the OEM market as the Pentium 4, model
