![]() ![]() ![]() ![]() With no further qualification, a 64-bit computer architecture generally has integer and addressing registers that are 64 bits wide, allowing direct support for 64-bit data types and addresses. Hence, a processor with 64-bit memory addresses can directly access 2 64 bytes (16 exbibytes or EiB) of byte-addressable memory. 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. In computer architecture, 64-bit integers, memory addresses, or other data units are those that are 64 bits wide.

Apple M1 Pro system: Macbook M1 Pro 18 configured with 32GB LPDDR5, 1TB SSD, MacOS Monterey (12.6.1). Ryzen 9 7940HS system: AMD reference motherboard configured with 4x4GB LPDDR5, 1TB SSD, Radeon 780M Graphics, Windows 11 64-bit. Testing results demonstrated in DaVinci Resolve BlackMagic, V-Ray, Blender, Cinebench R23 nT, and Handbrake 1:5:1. All 2022 and newer models of Razer Blade offer a 2-year limited battery warranty.The maximum battery life will decrease with time and usage of the system. Actual battery life may be less and can vary by usage, software, power settings, and other conditions. Testing was conducted by Razer’s technical team in April 2023 with the display brightness set to 33% brightness with backlighting off and wireless enabled.
