The range of integer values that can be stored in 64 bits depends on the integer representation used. In 2003, 64-bit CPUs were introduced to the mainstream PC market in the form of x86-64 processors and the PowerPC G5.Ī 64-bit register can hold any of 2 64 (over 18 quintillion or 1.8×10 19) different values. 64-bit CPUs have been used in supercomputers since the 1970s ( Cray-1, 1975) and in reduced instruction set computers (RISC) based workstations and servers since the early 1990s. 64 bits is a word size that defines certain classes of computer architecture, buses, memory, and CPUs and, by extension, the software that runs on them. The term 64-bit also describes a generation of computers in which 64-bit processors are the norm. 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. A computer that uses such a processor is a 64-bit computer.įrom the software perspective, 64-bit computing means the use of machine code with 64-bit virtual memory addresses. Also, 64-bit CPUs and ALUs are those that are based on processor registers, address buses, or data buses of that size.
Intel HD Graphics Driver 15.28.In computer architecture, 64-bit integers, memory addresses, or other data units are those that are 64 bits wide. Intel and the computer original equipment manufacturer (OEM) may not provide technical support for some or all issues that could arise from the usage of this generic version of software drivers. To avoid any potential installation incompatibilities on your OEM system, Intel recommends that you check with your OEM and use the software provided by your system manufacturer.
However, computer original equipment manufacturers (OEMs) may have altered the features, incorporated customizations, or made other changes to the software or software packaging they provide. These software drivers are generic versions and can be used for general purposes.
